Registry keys and Environment Variables used in the Windows AFS Client
----------------------------------------------------------------------
REGISTRY KEYS:
1. Service parameters
---------------------
The service parameters primarily affect the behavior of the AFS client
service (afsd_service.exe).
Regkey:
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters]
Value : LANadapter
Type : DWORD
Default : -1
Variable: LANadapter
LAN adapter number to use. This is the lana number of the LAN
adapter that the SMB server should bind to. If unspecified or set
to -1, a LAN adapter with named 'AFS' or a loopback adapter will be
selected. If neither are present, then all available adapters will
be bound to. When binding to a non-loopback adapter, the NetBIOS
name '%hostname%-AFS' will be used (where %hostname% is the NetBIOS
name of the host truncated to 11 characters). Otherwise, the NetBIOS
name will be 'AFS'.
Value : CacheSize
Type : DWORD
Default : 98304 (CM_CONFIGDEFAULT_CACHESIZE)
Variable: cm_initParams.cacheSize
Size of the AFS cache in 1k blocks.
Value : ChunkSize
Type : DWORD
Default : 17 (CM_CONFIGDEFAULT_CHUNKSIZE)
Variable: cm_logChunkSize (cm_chunkSize = 1 << cm_logChunkSize)
Size of chunk for reading and writing. Actual chunk size is 2^cm_logChunkSize.
Value : Daemons
Type : DWORD
Default : 2 (CM_CONFIGDEFAULT_DAEMONS)
Variable: numBkgD
Number of background daemons (number of threads of
cm_BkgDaemon). (see cm_BkgDaemon in cm_daemon.c)
Value : ServerThreads
Type : DWORD
Default : 25 (CM_CONFIGDEFAULT_SVTHREADS)
Variable: numSvThreads
Number of SMB server threads (number of threads of smb_Server). (see
smb_Server in smb.c).
Value : Stats
Type : DWORD
Default : 10000 (CM_CONFIGDEFAULT_STATS)
Variable: cm_initParams.nStatCaches
Cache configuration.
Value : LogoffPreserveTokens
Type : DWORD {1,0}
Default : 0
If enabled (set to 1), the Logoff Event handler will not attempt
to delete the user's tokens if the user's profile is stored outside
of AFS.
Value : RootVolume
Type : REG_SZ
Default : "root.afs"
Variable: cm_rootVolumeName
Root volume name.
Value : Mountroot
Type : REG_SZ
Default : "/afs"
Variable: cm_mountRoot
Name of root mount point. In symlinks, if a path starts with
cm_mountRoot, it is assumed that the path is absolute (as opposed to
relative) and is adjusted accordingly. Eg: if a path is specified as
/afs/athena.mit.edu/foo/bar/baz and cm_mountRoot is "/afs", then the
path is interpreted as \\afs\all\athena.mit.edu\foo\bar\baz. If a
path does not start with with cm_mountRoot, the path is assumed to
be relative and suffixed to the reference directory (i.e. directory
where the symlink exists)
Value : CachePath
Type : REG_SZ or REG_EXPAND_SZ
Default : "%TEMP%\AFSCache"
Variable: cm_CachePath
Location of on-disk cache file. The default is the SYSTEM account's
TEMP directory. The attributes assigned to the file are HIDDEN and
SYSTEM.
Value : NonPersistentCaching
Type : DWORD [0..1]
Default : 0
Variable: buf_CacheType
When this registry value is set to a non-zero value, the CachePath
value is ignored and the cache data is stored in the windows paging
file. This prevents the use of persistent caching (when available)
as well as the ability to alter the size of the cache at runtime
using the "fs setcachesize" command.
Value : ValidateCache
Type : DWORD [0..2]
Default : 1
Variable: buf_CacheType
This value determines if and when persistent cache validation is
performed.
0 - Validation is disabled
1 - Validation is performed at startup
2 - Validation is performed at shutdown
Value : TrapOnPanic
Type : DWORD {1,0}
Default : 0
Variable: traceOnPanic
Issues a breakpoint in the event of a panic. (breakpoint: _asm int 3).
Value : NetbiosName
Type : REG_EXPAND_SZ
Default : "AFS"
Variable: cm_NetbiosName
Specifies the NetBIOS name to be used when binding to a Loopback
adapter. To provide the old behavior specify a value of
"%COMPUTERNAME%-AFS"
Value : IsGateway
Type : DWORD {1,0}
Default : 0
Variable: isGateway
Select whether or not this AFS client should act as a gateway. If
set and the NetBIOS name hostname-AFS is bound to a physical NIC,
other machines in the subnet can access AFS via SMB connections to
hostname-AFS.
When IsGateway is non-zero, the LAN adapter detection code will
avoid binding to a loopback adapter. This will ensure that the
NetBIOS name will be of the form hostname-AFS instead of the value
set by the "NetbiosName" registry value.
Value : ReportSessionStartups
Type : DWORD {1,0}
Default : 0
Variable: reportSessionStartups
If enabled, all SMB sessions created are recorded in the Application
event log. This also enables other events such as drive mappings
or various error types to be logged.
Value : TraceBufferSize
Type : DWORD
Default : 5000 (CM_CONFIGDEFAULT_TRACEBUFSIZE)
Variable: traceBufSize
Number of entries to keep in trace log.
Value : SysName
Type : REG_SZ

Variable: cm_sysName
Provides an initial value for "fs sysname". The string can contain
one or more replacement values for @sys in order of preference separated
by whitespace.
Value : SecurityLevel
Type : DWORD {1,0}
Default : 0
Variable: cryptall
Enables encryption on RX calls.
Value : UseDNS
Type : DWORD {1,0}
Default : 1
Variable: cm_dnsEnabled
Enables resolving volservers using AFSDB DNS queries. (see
afsdb-freelance-notes).
As of 1.3.60, this value is ignored as the DNS query support
utilizes the Win32 DNSQuery API which is available on Win2000
and above.
Value : FreelanceClient
Type : DWORD {1,0}
Default : 0
Variable: cm_freelanceEnabled
Enables freelance client. (see afsdb-freelance-notes)
Value : HideDotFiles
Type : DWORD {1,0}
Default : 1
Variable: smb_hideDotFiles
Enables marking dotfiles with the hidden attribute. Dot files are
files whose name starts with a period (excluding "." and "..").
Value : MaxMpxRequests
Type : DWORD
Default : 50
Variable: smb_maxMpxRequests
Maximum number of multiplexed SMB requests that can be made.
Value : MaxVCPerServer
Type : DWORD
Default : 100
Variable: smb_maxVCPerServer
Maximum number of SMB virtual circuits.
Value : Cell
Type : REG_SZ
Default : <none>
Variable: rootCellName
Name of root cell (the cell from which root.afs should be mounted in
\\afs\all).
Value : RxNoJumbo
Type : DWORD {0,1}
Default : 0
Variable: rx_nojumbo
If enabled, does not send or indicate that we are able to send or
receive RX jumbograms.
Value : RxMaxMTU
Type : DWORD
Default : -1
Variable: rx_mtu
If set to anything other than -1, uses that value as the maximum MTU
supported by the RX interface.
In order to enable OpenAFS to operate across the Cisco IPSec VPN
client, this value must be set to 1264 or smaller.
Value : ConnDeadTimeout
Type : DWORD
Default : 60 (seconds)
Variable: ConnDeadtimeout
The Connection Dead Time is enforced to be at a minimum 15 seconds
longer than the minimum SMB timeout as specified by
HKLM\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters
SessTimeout
If the minimum SMB timeout is not specified the value is 45 seconds.
See http://support.microsoft.com:80/support/kb/articles/Q102/0/67.asp
Value : HardDeadTimeout
Type : DWORD
Default : 120 (seconds)
Variable: HardDeadtimeout
The Hard Dead Time is enforced to be at least double the ConnDeadTimeout.
The provides an opportunity for at least one retry.
Value : TraceOption
Type : DWORD {0, 1, 2, 3}
Default : 0
Enables logging of debug output to the Windows Event Log.
Bit 0 enables logging of "Logon Events" processed by the Network Provider
and Winlogon Event Notification Handler.
Bit 1 enables logging of events captured by the AFS Client Service.
Value : AllSubmount
Type : DWORD {0, 1}
Default : 1
Variable: allSubmount (smb.c)
By setting this value to 0, the "\\NetbiosName\all" mount point
will not be created. This allows the read-write versions of
root.afs to be hidden.
Value : NoFindLanaByName
Type : DWORD {0, 1}
Default : 0
Disables the attempt to identity the network adapter to use by
looking for an adapter with a display name of "AFS".
Value : MaxCPUs
Type : DWORD {1..32} or {1..64} depending on the architecture
Default : <no default>
If this value is specified, afsd_service.exe will restrict itself
to executing on the specified number of CPUs if there are a greater
number installed in the machine.
NOTE: Setting this entry to "1" may be required on hyperthreaded
systems to avoid crashes in the RX library.
Value : smbAuthType
Type : DWORD {0..2}
Default : 2
If this value is specified, it defines the type of SMB authentication
which must be present in order for the Windows SMB client to connect
to the AFS Client Service's SMB server. The values are:
0 = No authentication required
1 = NTLM authentication required
2 = Extended (GSS SPNEGO) authentication required
The default is Extended authentication
Value : MaxLogSize
Type : DWORD {0 .. MAXDWORD}
Default : 100K
This entry determines the maximum size of the %WINDIR%\TEMP\afsd_init.log
file. If the file is larger than this value when afsd_service.exe starts
the file will be reset to 0 bytes. If this value is 0, it means the file
should be allowed to grow indefinitely.
Value : FlushOnHibernate
Type : DWORD {0,1}
Default : 1
If set, flushes all volumes before the machine goes on hibernate or
stand-by.
Regkey:
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters\GlobalAutoMapper]
Value : <Drive Letter:> for example "G:"
Type : SZ
Specifies the submount name to be mapped by afsd_service.exe at startup
to the provided drive letter.
Regkey:
[HKLM\SOFTWARE\OpenAFS\Client]
Value : CellServDBDir
Type : REG_SZ
Default : <not defined>
Specifies the directory containing the CellServDB file.
When this value is not specified, the AFS Client install
directory is used.
Value : VerifyServiceSignature
Type : REG_DWORD
Default : 0x1
This value can be used to disable the runtime verification of
the digital signatures applied to afsd_service.exe and the
OpenAFS DLLs it loads. This test is performed to verify that
the DLLs which are loaded by afsd_service.exe are from the
same distribution as afsd_service.exe. This is to prevent
random errors caused when DLLs from one distribution of AFS
are loaded by another one. This is not a security test. The
reason for disabling this test is to free up additional memory
which can be used for a large cache size.
Value : IoctlDebug
Type : REG_DWORD
Default : 0x0
This value can be used to debug the cause of pioctl() failures.
Set a non-zero value and the pioctl() library will output status
information to stdout. Executing command line tools such as
tokens.exe, fs.exe, etc can then be used to determine why the
pioctl() call is failing.
Value : MiniDumpType
Type : REG_DWORD
Default : 0x0 (MiniDumpNormal)
This value is used to specify the type of minidump generated by
afsd_service.exe either when the process crashes or when a user
initiated is dump file is generated with the "fs.exe minidump"
command.
Valid values are dependent on the version of DbgHelp.dll installed
on the machine. See the Microsoft Developer Library for further
information.
MiniDumpNormal = 0x00000000,
MiniDumpWithDataSegs = 0x00000001,
MiniDumpWithFullMemory = 0x00000002,
MiniDumpWithHandleData = 0x00000004,
MiniDumpFilterMemory = 0x00000008,
MiniDumpScanMemory = 0x00000010,
MiniDumpWithUnloadedModules = 0x00000020,
MiniDumpWithIndirectlyReferencedMemory = 0x00000040,
MiniDumpFilterModulePaths = 0x00000080,
MiniDumpWithProcessThreadData = 0x00000100,
MiniDumpWithPrivateReadWriteMemory = 0x00000200,
MiniDumpWithoutOptionalData = 0x00000400,
MiniDumpWithFullMemoryInfo = 0x00000800,
MiniDumpWithThreadInfo = 0x00001000,
MiniDumpWithCodeSegs = 0x00002000
Value : StoreAnsiFilenames
Type : REG_DWORD
Default : 0x0
This value can be used to force the AFS Client Service to
store filenames using the Windows system's ANSI character set
instead of the OEM Code Page character set which has traditionally
been used by SMB file systems.
Note: The use of ANSI characters will render access to files
with 8-bit OEM file names unaccessible from Windows. This option
is of use primarily when you wish to allow file names produced
on Windows to be accessible from Latin-1 Unix systems and vice
versa.
Regkey:
[HKLM\SOFTWARE\OpenAFS\Client\CSCPolicy]
Value : "smb/cifs share name"
Type : REG_SZ
Default : <none>
This key is used to map SMB/CIFS shares to Client Side Caching
(off-line access) policies. For each share one of the following
policies may be used: "manual", "programs", "documents", "disable"
These values used to be stored in afsdsbmt.ini
Regkey:
[HKLM\SOFTWARE\OpenAFS\Client\Freelance]
Value : "numeric value"
Type : REG_SZ
Default : <none>
This key is used to store dot terminated mount point strings
for use in constructing the fake root.afs volume when Freelance
(dynamic roots) mode is activated.
"athena.mit.edu#athena.mit.edu:root.cell."
".athena.mit.edu%athena.mit.edu:root.cell."
These values used to be stored in afs_freelance.ini
Regkey:
[HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks]
Value : "numeric value"
Type : REG_SZ
Default : <none>
This key is used to store a dot terminated symlink strings
for use in constructing the fake root.afs volume when Freelance
(dynamic roots) mode is activated.
"linkname:destination-path."
"athena:athena.mit.edu."
"home:athena.mit.edu\user\j\a\jaltman."
"filename:path\file."
Regkey:
[HKLM\SOFTWARE\OpenAFS\Client\Submounts]
Value : "submount name"
Type : REG_EXPAND_SZ
Default : <none>
This key is used to store mappings of unix style AFS paths
to submount names which can be referenced as UNC paths.
For example the submount string "/athena.mit.edu/user/j/a/jaltman"
can be associated with the submount name "jaltman.home".
This can then be referenced as the UNC path \\AFS\jaltman.home.
These values used to be stored in afsdsbmt.ini
NOTE: Submounts should no longer be used with OpenAFS.
Use the Windows Explorer to create drive mappings to AFS UNC
paths instead of using the AFS Submount mechanism.
Regkey:
[HKLM\SOFTWARE\OpenAFS\Client\Server Preferences\VLDB]
Value : "hostname or ip address"
Type : REG_DWORD
Default : <none>
This key is used to specify a default set of VLDB server preferences.
For each entry the value name will be either the IP address of a server
or a fully qualified domain name. The value will be the ranking. The
ranking will be adjusted by a random value between 0 and 256 prior to
the preference being set.
Regkey:
[HKLM\SOFTWARE\OpenAFS\Client\Server Preferences\File]
Value : "hostname or ip address"
Type : REG_DWORD
Default : <none>
This key is used to specify a default set of File server preferences.
For each entry the value name will be either the IP address of a server
or a fully qualified domain name. The value will be the ranking. The
ranking will be adjusted by a random value between 0 and 256 prior to
the preference being set.
2. Network provider parameters
------------------------------
Affects the network provider (afslogon.dll).
Regkey:
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters]
Value : FailLoginsSilently
Type : DWORD
Default : 0
Do not display message boxes if the login fails.
Regkey:
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider]
Value : NoWarnings
Type : DWORD
Default : 0
Disables visible warnings during logon.

NSIS : "OpenAFSDaemon"
Specifies the display name of the AFS Client Service
Value : ProviderPath
Type : REG_SZ
NSIS : %WINDIR%\SYSTEM32\afslogon.dll
Specifies the DLL to use for the network provider
2.1 Domain specific configuration keys for the Network Provider
---------------------------------------------------------------
The network provider can be configured to have different behavior
depending on the domain that the user logs into. These settings are
only relevant when using integrated login. A domain refers to an
Active Directory (AD) domain, a trusted Kerberos (non-AD) realm or the
local machine (i.e. local account logins). The domain name that is
used for selecting the domain would be the domain that is passed into
the NPLogonNotify function of the network provider.
Domain specific registry keys are :
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider]
(NP key)
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider\Domain]
(Domains key)
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider\Domain\"domain name"]
(Specific domain key. One per domain.)
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider\Domain\LOCALHOST]
(Localhost key)
eg:
HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider
|
+- Domain
+-AD1.EXAMPLE.COM
+-AD2.EXAMPLE.NET
+-LOCALHOST
Each of the domain specific keys can have the set of values described
in 2.1.1. The effective values are chosen as described in 2.1.2.
2.1.1 Domain specific configuration values
-------------------------------------------
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider]
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider\Domain]
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider\Domain\"domain name"]
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider\Domain\LOCALHOST]
Value : LogonOptions
Type : DWORD
Default : 0x01
NSIS/WiX: depends on user configuration
0x00 - Integrated Logon is not used
0x01 - Integrated Logon is used
0x02 - High Security Mode is used
0x03 - Integrated Logon with High Security Mode is used
High Security Mode generates random SMB names for the creation of
Drive Mappings. This mode should not be used without Integrated Logon.
As of 1.3.65 the SMB server supports SMB authentication. The High
Security Mode should not be used when using SMB authentication
(SMBAuthType setting is non zero).
Value : FailLoginsSilently
Type : DWORD (1|0)
Default : 0
NSIS/WiX: (not set)
If true, does not display any visible warnings in the event of an
error during the integrated login process.
Value : LogonScript
Type : REG_SZ or REG_EXPAND_SZ
Default : (null)
NSIS/WiX: (only value under NP key) <install path>\afscreds.exe -:%s -x -a -m -n -q
A logon script that will be scheduled to be run after the profile
load is complete. If using the REG_EXPAND_SZ type, you can use
any system environment variable as "%varname%" which would be
expanded at the time the network provider is run. Optionally
using a "%s" in the value would result in it being expanded into
the AFS SMB username for the session.
Value : LoginRetryInterval
Type : DWORD
Default : 30
NSIS/WiX: (not set)
If the OpenAFS client service has not started yet, the network
provider will wait for a maximum of "LoginRetryInterval" seconds
while retrying every "LoginSleepInterval" seconds to check if the
service is up.
Value : LoginSleepInterval
Type : DWORD
Default : 5
NSIS/WiX: (not set)
See description of LoginRetryInterval.
Value : TheseCells
Type : REG_MULTI_SZ
NSIS : <not set>
When Kerberos 5 is being used, TheseCells provides a list of additional
cells for which tokens should be obtained with the default Kerberos 5
principal.
2.1.2 Selection of effective values for domain specific configuration
----------------------------------------------------------------------
During login to domain X, where X is the domain passed into
NPLogonNotify as lpAuthentInfo->LogonDomainName or the string
'LOCALHOST' if lpAuthentInfo->LogonDomainName equals the name of the
computer, the following keys will be looked up.
1. NP key. ("HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider")
2. Domains key. (NP key\"Domain")
3. Specific domain key. (Domains key\X)
If the specific domain key does not exist, then the domains key will
be ignored. All the configuration information in this case will
come from the NP key.
If the specific domain key exists, then for each of the values
metioned in (2), they will be looked up in the specific domain key,
domains key and the NP key successively until the value is found.
The first instance of the value found this way will be the effective
for the login session. If no such instance can be found, the
default will be used. To re-iterate, a value in a more specific key
supercedes a value in a less specific key. The exceptions to this
rule are stated below.
2.1.3 Exceptions to 2.1.2
--------------------------
To retain backwards compatibility, the following exceptions are made
to 2.1.2.
2.1.3.1 'FailLoginsSilently'
Historically, the 'FailLoginsSilently' value was in
HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
key and not in the NP key. Therefore, for backwards compatibility,
the value in the Parameters key will supercede all instances of this
value in other keys. In the absence of this value in the Parameters
key, normal scope rules apply.
2.1.3.2 'LogonScript'
If a 'LogonScript' is not specified in the specific domain key nor
in the domains key, the value in the NP key will only be checked if
the effective 'LogonOptions' specify a high security integrated
login. If a logon script is specified in the specific domain key or
the domains key, it will be used regardless of the high security
setting. Please be aware of this when setting this value.
3. AFS Credentials System Tray Tool parameters
----------------------------------------------
Affects the behavior of afscreds.exe
Regkey:
[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters]

Value : EnableKFW
Type : DWORD {0, 1}
Default : 1
Function: KFW_is_available()
When MIT Kerberos for Windows can be loaded, Kerberos 5 will be used
to obtain AFS credentials. By setting this value to 0, the internal
Kerberos 4 implementation will be used instead. The current user value
is checked first; if it does not exist the local machine value is checked.
Value : Use524
Type : DWORD {0, 1}
Default : 0
Function: KFW_use_krb524()
When MIT Kerberos for Windows can be loaded, Kerberos 5 will be used
to obtain AFS credentials. By setting this value to 1, the Kerberos 5

as part of the shortcut to afscreds.exe. afscreds.exe rewrites the
shortcut each time it exits so as to ensure that the shortcut points
to the latest version of the program. This value is used to determine
which values should be used for command line parameters. The current
user value is checked first; if it does not exist the local machine
value is checked.
The following subset of the command line options are appropriate for
use in this registry setting:
-A = autoinit
-M = renew drive maps
