Please help! Thanks!
This can and does happen on normal functioning Windows networks too. The solution is simple:

Disjoin the Windows PC from the domain, then join again and reboot. As always, be sure to backup the PC before you do anything. Also, before you begin, make sure you have access to a local admin account on the Windows PC; this will make life easier if you run into trouble and cannot join the domain again.
