We have Symantec Anti-Virus Corp 10.1 installed on our systems along with Deepfreeze 6. We have the virus definitions redirected to a D: partition which is not affected by deepfreeze so that Symantec software can stay up to date when the computers are restarted.
The main systems we are having issues with are HP D530's. Every so often (likely when the definitions are updated) when the computers are rebooted, they will show the XP logo and then flash a blue screen realy quick and reboot. some will keep doing this and some will come out of it after a while. I have found that booting to recovery console and run an fdisk /mbr it will resolve the problem most times. After doing this however, when looking in device manager under non plug and play devices the savrt device has an "1" on it.
The blue screen that is appearing references the file savrt.sys every time. It also has the message "DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS" and the stop code is 0x000000CE.
We have many other types and makes and models of computers and we've only seen it affect the HP's so far. I believe there are some 5700's being affected as well.
Any thoughts or ideas on what to try would be great. If I left out any info that may be important let me know.
Thanks in advance.
