What type of hardware is it running on?
Its not running on hardware from a big manufacture (eg Dell or HP)
CPU Intel-Core duo 2.4GHZ
RAM: 4GB
OS Windows Server 2008
What process is causing the BSOD?
SEMSRV (symantec endpoint protection manager)
I ran test with SEPM web service and SEMP launcer services enabled and the SEPM service disabled. We had a system run for weeks with those 2 services enabled and SEPM service disabled and the system ran with no problems. I enabled the SEPM service and it BSOD is seconds.
Have you tried the latest version, 12.1.6 MP2?
No, I didn't know that there was an update until a few minutes ago. I have to figure out how I can get it for testing. I looked at the release notes for it and there no mention of a BSOD fix in that release.
