Some time ago I asked about joining XP computers to a windows 2003
domain for a user that isn't an administrator.
Now I have a related problem: I can't re-join the computer if I
reinstalled Windows XP and the computer object is already created in AD.
The user has the "Create/Delete Computer Objects" permission. What else
should I set?.
Thanks!
