To set up the scenario: One of our techs set one of the domain controllers to use Microsoft time. The time IS correct (including Time Zone) and DOES match the other domain controller's time; it was previously incorrect, however.
Since the change, no users can connect via \\servername\share or \\servername.domainname.com but \\ip\share works fine. I cannot even access it from the other domain controller with which I know both have the same time. The servername DOES resolve to the correct IP address. Also, strangely enough, \\domainname.com works as well which resolves to the same server. Finally Everything that I have tried does resolve to the same, correct IP address.
The error is:
login failure: The target account name is incorrect.
I believe it is time related but since the times are correct and match I'm not sure.
Anyone know what might cause this?
