Disable Windows XP Professional Fast Logon Optimization feature

So Windows XP Pro got the great feature that helps speed up login time. Fast is good, unless it doesn't work.

Well, the Fast Logon feature works, but just not the way "normal" desktop administrator / users would expect.

Bottom line on how to disable this? Use either local group policy or AD group policy to set this value to ENABLE:

Computer Configuration\Administrative Templates\System\Logon\
Always wait for the network at computer startup and logon

Some of the symptoms of this feature are:

• users not getting network drives at logon
• users net getting User Configuration GPO settings
