We recently changed the password on our Domain Administrator account (Administrator). However, after that, we can no longer login to any PC on the domain with domain\administrator. I can login to the Domain Controller with the credentials and when a user on the domain is prompted for Admin rights to update or install new software, the domain\administrator account credentials work.
I have verified that the trust between the domain and local PC is good. I also looked in Event Viewer on the domain and see the failed attempts for the domain login. I know the password is correct.
Any help will be appreciated.
