0x00000096 XP Professional

I had the same issue a few years ago, funny I can remember it but it was just to strange to forget about. I was trying to view the mini dump file about the issue to hopefully resolve but my keyboard wasn't exactly a very good one. It worked but basically sucked so I actually plugged a better one into the problemed PC and the issue vanished! I have noticed that this issue can be harware related or also database related. Does this occur when the workstation is attempting to access a database? I have seen 'similar' messages when a workstation has the executable (front-end) locally and is trying to access a MsSQL table on a server (back-end) and one of the related tables is no longer where it is expected to be on the server.

I forgot:

- Problem started about 1,5 month ago, wks are working from 1,5 year....no new software....

You could check your network to make sure you don't have a flaky server cable or a bad switch.  Since the computers are all having the issue could it possibly by related to the network dropping off for a short period of time and a database losing connectivity or an application complaining?

PC's don't use any database except the MSSQL for autocad...but is not active....if can help switch are all cisco managed 48port and LAN is certified and tested every 2 month, cat6 cables..so not a problem....if can help it seem the problem pop out using ALLPlan 2006

Most often than not, this is a driver issue.
Check the Dell Support sites for updates of the drivers that are on your Dell driver CDs.

If that doesn't work, please enable the creation of minidumps and attach some here.
(Dumps aren't stored in the \system folder, but in \windows\minidumps)

ps:
.dmp files must be renamed to .txt (or any other supported attachment type) before you will be able to attach them.

My minidupm creation is anebled...but even if this the folder minidump does not exist and on my c drive there are no .dmp files around....i'm searching over and over and the problem is still presenting sometimes....this morning:

2 pc hang out durin autocad 2008...blues screen with invalid_work_.....ecc ecc..same error
1 pc hang using allplan...could be my Sophos enterpise antivirus?
I run the verifier.exe from xp and after 3 hours there were no error shown.
Memory test go good
CPU Orthos stress good
the only one strange thing is that i'm not able to re-enable hidden file show.
i did the registry hack...and nuthin...antispyware don't find viruses...sophos keep finding sometimes autorun.inf on usb keys and sumetimes conficker in various version...but always clean...could be related?

Is the Paging file set on the C Drive? If not, thats why you are not getting a dump file....

Did you check the Dell site for driver updates, as I suggested above?

If you don't get any minidumps, and your pagefile resides on C:, then the creation of minidumps needs to be enabled:
My Computer > Properties > Advanced > Startup and Recovery > Settings > Save debug information.

I took away sp3, put old drivers..and all works fine.....

That seems to indicate that some of the old drivers - or at least one - do not work together with SP3. This may very well happen.

I once encountered a problem on a W2k workstation after upgrading to SP4 that could only be resolved by updating the printer drivers.

There is a chance (although no guarantee) that minidump analysis will reveal the driver in question.
