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.
