I have a workstation that was using Windows 2000 connected to Server 2003 AD. I moved the documents and settings contents of the user to a new fresh install after the user was created on first login. This new machine replaced the old which is off the network. Now the group policy permissions aren't working for a user IE User X in Group Y cannot read write to Share Z when Group Y has full access to the share. I tried logging in as an admin in safemode and renaming the user to _X then created a fresh user. And copied specific application data, outlook firefox etc, and documents and the problems appears to have come up again. If the user logs into another machine they can get access to the share and if the another user with access to those shares logs into this machine they will get access. Should i rename the NTUSER.DAT or some other file to reset the credentials?
