Has anyone had this problem. I came into the office this morning and the server was locked up. On the screen I could control the mouse, but the screen just had the background color. I couldn't break out of this, nor could I reboot the server with Ctrl+Alt+Del. So I could move the mouse around but not do anything else. I finally powered the server down and brought it back up. I checked the logs and everything stopped reporting at 11:18 the night before, there were no goofy errors prior to that time. My questions are, what could cause the server to stop responding in that fashion? And, if I do get in a situation where I can move the mouse, but nothing really else, is there some way I can safely bring the server down? Any advice or similar experices would be helpful. Thanks
