Domain Trust Issue

We have an older PC that wasn't configured with our new DNS servers so I logged in and made the change. I logged out and attempted to sign back in but get the message, "the trust relationship between this workstation and the primary domain failed," and "The security database on the server does not have a computer account for this workstation trust relationship." I attempted to login as the local admin but get the same errors. I also unplugged it from the network, rebooted and attempted to login but get the message that there are no logon servers available.

I've had to do this in the past and have always been able to login as the local admin, remove it from the domain and then re-add it and it's worked fine. This is a Windows 7 x64 machine.

Sounds like its still trying to login to the domain with cached credentials instead of locally.

Verify the computer has the correct time.
In the logon screen put .\administrator to logon with local admin and password.

The second issue you may have is the secure channel is broken between that computer and the domain.

Search the domain for the computer name. If the computer is in the domain just delete it or reset it (right click > reset)
On the computer be sure the DNS servers are configured properly.
Make sure all IP info is correct (is it static IP or DHCP, etc...)
If the computer is joined to the domain, go through dis-joining the domain by adding it to a workgroup (WORKGROUP) and restart.
Logon again and join the computer back to the domain (use the full dns name of the domain and NOT the short NETBIOS name. Make sure to use something like your.domain.com)

It will join and you will be happy
OR
It will still not join and then we have to start doing more investigation such as pinging the DNS servers or using nslookup to troubleshoot.

Perfect, thank you! The second step seems to have resolved the issue.
