jaltman-afsd-loopback-w2k-and-noipc-patches-20031121

Browse Source 
* Change handling of CM_ERROR_NOIPC to return an Access Denied
   error instead of a Bad Network Name error.  The reason is that
   Bad Network Name results in a subsequent query by many apps
   to find a good network name which cannot be accomplished.
   Access Denied is more appropriate and results in an immediate
   error return.

 * Disable the Loopback Adapter hack for operating systems prior
   to Windows XP because the Loopback adapter on previous versions
   does not perform loopback operations on Broadcast messages
   which are necessary for the proper registration of the
   NETBIOS name for the AFS Service.

 * Many minor corrections to uninitialized variables; spelling
   errors; formatting errors; etc.
