BSOD - probably caused by : ntkrnlmp.exe - Server 2008

Hi,

I know it's not quite win7, but I'm hoping someone can help.

The OS is Server 2008 SP 2 running as a Terminal Services server.

About a week ago it started crashing with BSODs. The only recent change was installing a new Xerox workcentre network printer 3 days earlier. It crashed 5 times over a day and a half, and by this time I was trying to work out what was going wrong.

Ran Windows Memory diagnostic after reboot - found no problems.

Chkdsk found no problems with discs either.

Updated the video drivers to current ATI drivers (were previously MS). And uninstalled all the Xerox software and reinstalled printer with driver only.

It then ran fine for nearly a week, but blue screened again last night.

I've posted the analysis of the latest memory dump and attached some older dump files.

Help would be much, much appreciated.

Thanks.
.

Ok, thanks for the response.

Zip file attached as requested.

Thanks.

Many thanks for the response.

From my amateur reading of the dumps I thought the crashes may have been due to ESET. And some Dell diagnostics had pointed me in the direction of the NIC - but all things being equal, since they had worked happily for a while now, I was reluctant to change them...

But following another BSOD this morning I've taken the plunge and updated both.

As a side note, since doing this another problem seems to have been resolved - a process / print routine that in the last while (about 2 weeks before crashes started) had become excruciatingly slow has gone back to normal. Seems to support the idea that one of these was the culprit.

But only time will tell - now just have to wait and see.

Thanks again.

Hello,


This is my first time posting here. my apologies if posting incorectly.
Would please help me analyze the attached file? I experienced a system crash and I haven't been able to figure out the root cause of the issue.

Let me know if additional information is needed. I figured the file should contain all needed information about the system.

Many Thanks in advance
