Strange one here. Client has a 2008 foundation server domain based network with windows 7 Pro laptops joined to the domain.
I have one user who takes their laptop home at night and then plugs back into the network in the morning using CAT 5 Cable. Yesterday while I was there she arrived and plugged her laptop into the network and booted it up. After pressing - Ctrl /Alt / Delete no username or password prompt appears on the screen.
If I disconnect the network cable and reboot the username and password prompts appear. i can then reconnect the network cable and log in with no problems.
Anyone ever see this?
