Windows 7 workstations intermittently give the error : "The security database on the server does not have a computer account for this workstation trust relationship"

Hello All,

This error comes up from time to time on Windows 7 machines logging on to a Windows 2003/Windows 2008 R2 infrastucture. Cutting off the net access and then logging in using the cached password fixes it for a few months only. I have done the remove and rejoin thing , Computer attributes (SPN and DNS name are identical to the full computer name on the machine) . Is there any way to stop this from happening ?

Thanks for any help on this.

When this happens what we do is

1. remove the PC from domain, restart
2. rename the PC, restart
3. rejoin to domain, restart

Some say that you don't need all of the restarts but for us that is what works.

When that doesn't work, what we do is when we rename the PC we make sure we're using a name that has not been used before.

There are 300 computers and I have already tried that as stated in the question. Changing a computer's name does not change the SID. The problem is intermitttent and once it is logged in using the cached info and the the net cable reattached it is good for about 1-3 months before it happens again.

I understood that you rejoined/removed but your post didn't say anything about renaming or restarting. Some people like to make those changes without restarting. Doesn't changing the name create a new computer account?

Also you might want to check dns info with nslookup on the PCs in question, or check your record scavenging because faulty dns records will cause this as well.

I have tried this on three of the machines naming them completely different and it seems to be working now. Only time will tell. Thank you for your help

I will post a follow up if it comes back on any of the machines recorded as having this done. Seems to be a perm fix for this right now though.
