I know this is the Windows 2000 forum but just incase your test pc has windows xp installed on it...
You need to turn of fastboot to make windows xp behave like windows 2000, if you don't do this you might have problems with policy's not taking effect.
To do this create a policy that turns of fastboot
Under computerconfiguration\administrative templates\system\logon\
enable this setting
Always wait for the network at computer startup and logon
If it is a windows 2000 computer just ignore this post.
