A user has a Dell Latitude E4200 running Windows 7 Professional 32 bit. The machine has an internal Broadband card, Wifi Card and an Ethernet port (which is also in the docking station).
When they connect the machine to the LAN via either the Ethernet card or Wifi, and can see the domain, the machine gives the the error that their Trust Relationship has failed with the domain controller. This also shows up in the NetLogon Event error in the Event log under System.
If they are NOT connected to the domain, they can log in just fine using the cached credentials.
I have renamed the computer while connected to the domain and rebooted, but this did not solve the problem.
I want to avoid Un-joining the domain and re-joining as this will result in changes in their configuration and will take more time to put things right.
Any other ideas on how to fix this issue.
