Windows 2008 unexpected shutdown after adding DFS Folder.

We're experiencing an odd issue with our DFS servers, whereby, both servers unexpectedly reboot after adding a new DFS folder target/replication group.  Two servers, both running Windows 2008R2 sp1 with most recent updates.  Updating the firmware (BIOS, Chipset, SCSI...etc) on both servers did not resolve the issue.  Checked resources (disk space, cpu, ram) and everything appears ok. There are approximately 30 existing folder targets which have been working fine.

Checked minidump file, shows Unexpected_Kernal_Mode_Trap, with a code of 0x7F and a reference to ntoskrnl.exe.  Installed a potential Hotfix from Microsoft, KB2885978, which references the aforementioned stop error.  After a reboot, the issue still persists when attempting to add a new folder target.  Wondering if anyone else has ever experienced this issue.

This issue is not related to DFS, DFS has nothing to do with unexpected reboot

Please check physical Memory for issues
Also sometimes SCSI / RAID driver upgrade creates new issues instead of resolving issues

To me this seems to be either RAID/SCSI drivers or issue with one of the updates.

We edited the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control.
Modified the existing WaitToKillService value from 20000 to 60000.
