Bad Pool Caller - Blue Screen

[Guest]

We have about 25 Compaq SP750 Workstation Computers with Windows 2000
Professional.

Every one of these computers crash after installing Windows Defender. The
crashes are always an unexpected reboot, or a blue screen with
"Bad_Pool_Caller" and then a reboot.

If we remove Windows Defender, the problem goes away. When we re-install
Windows Defender the problem returns.

There must be a problem with Windows Defender, Windows 2000 Professional and
the Compaq SP750 Computer.

Any ideas?

Thanks,
RChattler

involves an at least superficially similar message on a similar system--it
lists a particular hardware driver and files. Do these exist you your
systems?

I'm not sure how best to test this. You could try using recovery console to
physically remove the files, as noted in the article (rename them so you can
put them back, etc.)

Perhaps there are newer drivers available at the web site referenced--that
page appears gone, but the vendor's site still exists.

The other useful course of would be to capture a dump of the crash. Is
there any information in System Event log records at the time of these
crashes?

I read the article kbid=310527. I do not have the video card listed or the
driver in question. The video cards in the machines I checked are "ATI Fire
GL2".

I will re-install Windows Defender and the next time I get a blue screen I
will write down the "Bad Pool Caller" information and check the event log.

I will them post the information that I gather about the crash.

Thanks,

Thanks - This does have the sound of a software conflict of some sort--if
all the machines are seeing it--it'd be good to pin it down if possible.

The problem occurred again. The blue screen crash goes by to quick to write
down any information, but the event viewer had the following event after
rebooting the system.

The computer has rebooted from a bugcheck. The bugcheck was: 0x000000c2
(0x00000007, 0x00000b8a, 0x856e9540, 0x856e9548). Microsoft Windows 2000
[v15.2195]. A dump was saved in: C:\WINNT\Minidump\Mini051106-02.dmp.

I have all of the minidump files, since I installed windows defender, and I
can send them to someone if that would help.

Thanks,

I'm trying to remember how large a mindump file is.

Can you zip one up--drag it to a zip folder--and let's see how big it is?

I'd be happy to have you send it to me-- bill_sanderson @ msn.com

(remove the spaces) and I'll make sure it gets to somebody at Microsoft.
You should probably be aware that such a dump can contain confidential
information. If you'd prefer to send it directly to a Microsoft staff
person, let me see what I can find out--and let's see how big the zipped
file is, too.

Dear Bill,

I really appreciate your help with this matter.

I sent an email to you with a zip file that contains 3 minidump files.
Expanded, the minidumps are 64k each. Zipped, the three together are just
21k.

I Hope these files help with this Windows Defender mystery.

Thanks,
