Hello,

This server has been running beautifully 24/7/365 since it was built in 8/2005. It's run for 200+ days between restarts and is a reliable workhorse for my small office. I keep it connected to a small LCD monitor and wiggle the mouse every so often to wake it up and check it out, it's always fine...except today.

The mouse wiggle turned on the backlight of the LCD, but no image. All indications (monitor status light turned from yellow to green) were that the server had awakened the monitor, but I swapped monitors with a CRT just to be sure...same issue. If I touched a key on the keyboard I heard a beep from the mainboard speaker, just as usual when there are no dialogs open. The server was functioning fine.

I logged in via RDP and all seemed well, except for the mmmc.exe errors it kept throwing up at me, which it's been doing lately {Faulting application mmc.exe, version 5.2.3790.1830, faulting module ntdll.dll, version 5.2.3790.1830, fault address 0x00038bdb.}.

Using RDP, I rebooted the machine and all was well with the local monitor. It now awakens the monitor fine, and is 100% back to normal as far as I can tell, but I am wondering what could have caused this situation. Just a glitch, or a warning of future problems? Has anyone had or seen this problem before? Possible causes? Thanks all.

If it was a 1 time glitch in 3 years I would consider myself lucky!

I guess you're right, I was just wondering if others have seen this problem in the past. If I didn't have RDP set up on it my only other option for a graceful shutdown would have been pulling the plug and having the UPS software initiate a soft shutdown, or trying to blindly restart it with the keyboard.

I took the time to set up RDP on another domain PC and instructed the user how to connect in the event of my absence.
