We had a tech resign yesterday so we needed to change our administrative passwords. We have a domain that consists of a single domain controller and no member servers. It has about 20 clients attached to it. We changed the administrative password and rebooted the server. We entered the new administrator password and it came up fine. However, now when we now go into AD Users & Computers we get the following dialog:
"Naming information cannot be located because: The Logon attempt failed."
The AD Users and Computers MMC will then come up but the snap-in has a red X on it. If we try to connect to the domain from within the MMC we get this dialog:
"Windows cannot connect to the new domain because: the logon attempt failed."
Bottom line is why did we lose the authentication to AD and is there anyway to recover it? I have seen some documentation on the use of NETDOM but I'm not sure how to proceed.
Any assistance will be most humbly appreciated.
