I'm working in a temporary location. We have a single network drop.

We have a D-Link 5 port switch plugged into the drop, and two desktop computers plugged into the switch without any issues.

Trying to add a 3rd machine (a laptop) results in a error when we try to log in:

"The security database on the server does not have a computer account for this workstation trust relationship"

If I unplug the cable from the switch, and plug it in directly to the wall, then I can log in.

Neither of the other two machines, plugged into the same switch, have this problem. I've tried switching around the ports, different cables, and a different, brand new 8 port switch, and nothing helps: unless plugged directly into the wall, the laptop cannot log in.

Any ideas?

Googling I found fixes for the error here and here, hope they help.

Not really the issue - there isn't actually a problem with the domain controller or the local settings, since changing the way the machine connects to the network fixes the problem. – chris Apr 16 '12 at 16:43
Well - I figured I had nothing to lose by trying these, and strangely enough it appeared to have fixed the problem. No idea why having a switch in the network path would affect this, though. – chris Apr 17 '12 at 2:43
