If you are having trouble with the Integrated Logon operations it is often useful to be able to obtain a log of what it is attempting to do. Setting the Debug registry value:

[HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\NetworkProvider]

REG_DWORD Debug = 0x01

will instruct the Integrated Logon Network Provider and Event Handlers to log information to the Windows Event Log: Application under the name "AFS Logon".
