Since the installation of the July Microsoft updates, my server shuts down at 00:58 every Sunday morning, every week. Then fails to restart, stuck at the blue screen Kernel_Data_Inpage_Error.
The server had been working fine for months before July. I've looked through the Task Scheduler and the only task that runs at 1am is the Maintenance Configurator task, but that runs every day. So if that were the problem I'd expect the server to stop every day at about 1am.
The server only runs one application, which this week I scheduled to stop at 00:45, however, the server still stopped, but at 01:08.
I've run memtest86 from a boot CD for 3 hours and found no memory problems. The C drive is new, but I ran chkdsk /scan anyway and no errors were found.
I've installed the August updates, but that didn't change the situation. I'd appreciate any thoughts or ideas please.
