Over the weekend we were going to migrate to a new domain controller (both the old and the new are Server 2008 r2). We had completely replicated all of the settings from the old server onto the new server and everything seemed to be setup and ready to go. When we tried to log the first Windows 7 workstation into the new domain we were getting the message "The trust relationship between this workstation and the primary domain has failed." From what we read about this, the way to fix it is to logon to the workstation with the local administrator account and then disconnect from the domain by switching to a Workgroup, then reboot and try and rejoin.
We followed all of the steps; we switched to a workgroup and then rebooted and logged back in as the local adminstrator. We then tried using the Network ID wizard to rejoin the domain but we kept getting the same error saying "The network path was not found."
We struggled with this for some time but eventually had to give up and put our old server back into production. As soon as we connected the old server all of our other workstations were able to connect to the old domain perfectly fine except the one Windows 7 workstation that we had switched to Workgroup when we were trying to connect to the new domain controller.
Now no matter what I try on this workstation I cannot reconnect it back to the old domain. Every time it comes back saying "The network path was not found." We even tried deleting the Computer account on the server hoping that would allow it to rejoin but no dice.
If I go into C:\Users I do see the original user account folder (knolan.CEPP) listed but the odd thing is that if I go Control Panel>User Accounts>Configure advanced user profile properties I see a user account listed as "Account Unknown" with a size of 2.46GB. I'm not sure if it is related to this issue or not but I have never seen an Account Unknown listed before, especially one with that kind of size.
Any suggestions on what I can try to get this workstation to rejoin the original domain? I am out of ideas and this is our only user having any issues at all.
