BSOD on 3 of 4 Win7 Machines - Cause mrxsmb10.sys

[bdphaneuf]

I am getting a BSOD on 3 of 4 PC's in the office. This started occurring in early Feb. I have tried updated all the video drives and network drivers on the workstations and servers. Tried to run the hotfix related to mrxsmb10.sys (says update not necessary or something to that effect). This is happening with both Symantec and ESET Anti-virus installed. I am really stumped at this point.

My first time posting here so I hope I am posting all the necessary information.

I am including a zip file of requested files for the good machine as well.

Just an FYI.

E,P, and T. Virtually all the crashes were memory exceptions with winword.exe the active process after approx 8 hours of uptime.

"J" has only one crash and it is related to iastor.sys.

Since almost all of these point to a common cause I wouldnt look at the local machines setup. You have removed Sonic, updated their drivers and the crashes are continuing.

I might look at winword.exe or perhaps the network since this indicates that a problem occurred in the SMB redirector file system.

What version of winword? Where is office located?, etc

They all have Office 2007 from Open License agreement installed on the C: drive. Folder redirection is enabled and I have wondered if that possibly has something do with it because of the references to SMB. I have debated stopping the folder redirection but it allows backups of the My Documents folders for people that forget to save all important data to the network shares.

We don't have any issues on the 5 workstations still running Win XP nor the 1 Win7 PC.

We are running Server 2003 R2 SP2 if that helps in anyway.

The "p" zip file is the one with only 1 dump file from a year ago. The "j" file is the most vocal and frustrated user. He has lost work several times while working near deadlines.

I added an additional 4GB of memory for a total of 8GB to "j" and "t" machines Monday evening and had a BSOD on the "t" machine Wednesday.

This is one of the scratch your head and go Hmmm things.

Thanks for your feedback.

Are there any common factors between the machines that work and those that dont?

Different network subnet/switch/router? Different physical location?

Do they are re-direct to a single machine or drive?

I am in the dark of course.

It is an office of 9 people. One Gigabyte switch for the backbone, a data server, an exchange server, a terminal server and a backup server with DFS for the user data.

Not going to be much help I am afraid. Have you asked on Technet?

I don't have a Technet subscription so I haven't tried that.

I was looking at that on Friday before I posted here. I think that is what I am left with.

Thanks,
