User logon problems are sometimes hard to troubleshoot. Have you checked the Application log on the machine in question? There might be (most likely) some errors in there from source Userenv (ID’s 1053, 1054).
Turning on Userenv debug logging will also help in troubleshooting user logon problems. You can do this by adding a Registry key:

– Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
– Value: UserEnvDebugLevel
– Value Type: REG_DWORD
– Value Data: 10002 (Hex)

The log will be located in: %systemroot%\debug\usermode\userenv.log.

In the log you will exactly see what happens during logon at what time. If you see a large difference between times you’ll know what part of the logon process is causing the long delay.
