Solved BSOD APC_INDEX_MISMATCH, Network

[markgecs]

Getting this BSOD randomly when working on network files from a Novell drive. It's on a Dell Optiplex 3010. I uninstalled/installed the network driver which made no difference. Ran the Dell hardware diagnostics and found no problems. The problem only comes up once or twice a day, usually when the user is working in Excel/Word/PPT on a network file. I'm at a loss with this one, can anyone offer some help?

thanks - mark

Hello Mark and welcome to the forums, had a look at your crash dumps, couldnt find anything conclusive, it seems that your early BSODs were being caused by the Novell drive but once updated the dumps became silent about the cause, please enable driver verifier and allow it to cause a crash on your system and then post the new sfdiag output here. heres a tutorial on how to enable and disable driver verifier:

Driver Verifier - Enable and Disable

Warning: If you can not boot into windows normally after enabling Driver Verifier please boot into Safe Mode and then disable Driver verifier

Also out of curiosity, what virus protection do you use? I didn't see any listed in your program files.

Thanks for the reply. I'll run the Driver Verifier later this morning and post up the results. The virus scanner is Trend Micro OfficeScan.

Enabled Driver Verifier as per the instructions here and rebooted. Immediate BSOD before Windows got to login screen. Looks like Novell is the culprit.

After disabling Driver Verifier, I uninstalled/re-installed the Novell driver and gave it back to the user. I just realized I probably should have enabled Driver Verifier again after re-installing Novell to see if that fixed the problem. Should I try that?

Here's the dump files.

Yes please do and see if it continues to cause BSODs

I've left this for a week to make sure the problem was solved and it looks like it is. The fix was not reloading drivers, but turning off file-caching under advanced settings in Novell Properties. No more BSODs.
