Problem with server file system filter driver???
« on: January 19, 2006, 05:53:05 AM »
Hi! We are having a strange problem on our MS 2K Std Server as described exactly in MS support article 830265 (http://support.microsoft.com/?kbid=830265). I followed all directions supplied in the article to no avail, but when I disable Avast On-Access scanner - bingo, no errors. The article claims that the problem may be due to a filter driver issue. Any ideas? At the moment the antivirus is disabled, but this is obviously not the ideal situation...

The KB article describes a number of symptomps. Do you suffer from all of those, or just some? (in that case, which ones?)


Is there any other low-level software installed on that machine? E.g. an online backup software? Has there ever been a different AV product installed on that machine (that might have been incompletely uninstalled)?


Thanks

Yes, we are suffering from all symptoms described, which is why I'm fairly sure the problem lies here.

Yes to both questions, too. Veritas was installed and I found and deleted the driver as instructed (we do not use veritas any more so it is no problem getting rid of it). I have confirmed that the driver has been deleted and restarted. I'm sure it has something to do with that. There had been another antivirus before yours (I don't remember which it was, but it was uninstalled through the control panel). Any ideas how I can find what else may be conflicting with avast!?

Please use the Drivers.exe utility to get a list of loaded drivers
http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/drivers-o.asp

Post the list and I'll try to identify which drivers might be causing the problem (and if they are not in use by any program any more, we can then try to deactivate them).

Thanks

Thanks! I've attached it as an jpeg, but if you want it in the post I can scan and OCR it.

Hmm, I don't really see any suspicious entries there, but it's possible I missed something because the jpeg not very easy to read. Do you think you could post it in a text version? Just redirect the output of the drivers.exe program to a file, such as

drivers.exe > drvlist.txt


Thanks

Any news? We've been running without an antivirus on the server now for a while. Getting a bit nervous...

First, let me apologize for the delay. :-\

The fact is, I'm still not sure what may be causing this mysterious problem. I went through the list of drivers loaded on the server, and didn't find ANYTHING suspicious at all. In fact, it's almost suspicious how clean the listing is - it's like it was a freshly installed machine...

I have one more question: so, right now, there's no backup software installed on the server? You said BackupExec USED TO be there, but isn't anymore? Or any other similar program?

Also, could you please ZIP the whole \windows\system32\drivers directory and upload it to ftp://ftp.avast.com/incoming ? (please note that you won't have READ access to the ftp server, just write - so you want be even able to see what you just uploaded).


Thanks
Vlk

Thanks for the reply, Vlk. We use NTBackup at the moment. Crappy on @k server because there is no Shadow copy, but it does the job. There is also a custom database program that the client uses (real-estate software). I'll see if I can get any information on it for you. Anything in particular I should ask the software developper? I will upload the driver directory for you now.

Thanks again for your help. Shame you couldn't make it to Oz... We'll have to party on without you ;-)
