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 Bit 0 of the TraceOption registry value:

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

  REG_DWORD   TraceOption = 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".
