About a day ago I logged off of my Windows 2003 Server box and proceeded to leave the office for the night. When I left, the screen "Closing Network Connections" was up. However, when I came back this morning that screen was still there. It seems not to have made any progress nor has it returned to the CTRL+ALT+DEL screen. I'm considering forcefully rebooting and running the hive tool. Does anyone know what could be causing this?
