We have a 2003 Server that is bluescreening about once a week. We've updated all drivers etc..., but it continues to happen. The output of the dump file is this: BugCheck A, {4, d000001b, 1, 8083d262} Probably caused by : ntkrnlmp.exe ( nt!KeDelayExecutionThread+4d5 ) Followup: MachineOwner --------- ******************************************************************************* * * * Bugcheck Analysis * * * ******************************************************************************* IRQL_NOT_LESS_OR_EQUAL (a) An attempt was made to access a pageable (or completely invalid) address at an interrupt request level (IRQL) that is too high. This is usually caused by drivers using improper addresses. If a kernel debugger is available get the stack backtrace.

I'm guessing hardware, but I really don't know what.

Hi, Please check the following KB to see whether you can resolve the sisue. http://support.microsoft.com/kb/910835 If the issue continues, I would like to suggest that you contact Microsoft Customer Service and Support (CSS) via telephone so that a dedicated Support Professional can assist with your request because we find it seems to be system crash issue and we need to analyze the crash dump file to narrow down the root cause of the issue. Unfortunately, it is not effective for us to debug the crash dump file here in the forum. To obtain the phone numbers for specific technology request please take a look at the web site listed below: http://support.microsoft.com/default.aspx?scid=fh;EN-US;OfferProPhone#faq607 Hope the issue will be resolved soon.

I have a case open, but I thought I would go both routes to cover every possible angle. I've found some other sites with the same exact blue screen since it's a HP Proliant DL 360 G4.
