We're experiencing issues with our Windows 2003 server, which runs SQL Server 2005 SP1. We notice that sometimes the entire server becomes unresponsive and I captured a screenshot of the task manager when this happened. I noticed that the processes are not displayed during this time and all of the memory information and handles disappear (as shown in the screenshot). Does anyone have any ideas as to what could be wrong with this sytem? I'm planning to take it down over the weekend to run Memtest86.
The issue is resolved by a reboot, but I'd like to figure out the cause of this and get it fixed.
I also tried to run a ping when this occurred and I got the following error in the event log:
"Application popup: ping.exe - Application Error: The application failed to initialize properly (0xc0000142). Click on OK to terminate the application."
