RE: BAD_POOL_HEADER crash in rpcxdr.sys (benker)

I looked at the version of my "rpcxdr.sys" file and it is "8.0.1969.1"

There may be a fix from Microsoft. Thanks to:

I noticed that Microsoft has a new RPC driver:

RE: BAD_POOL_HEADER crash in rpcxdr.sys (benker)

I have also been getting bluescreens of death on my WinXP SP2 box with SFU 3.5 installed (McAfee VirusScan v8.0i also). Our corporate IT group has been working with Microsoft Technical Support and sending core dumps from my PC. Just an hour ago the Microsoft folks came back with that it is a problem with the RPC driver as you can see below.

Any idea on how to get Microsoft to fix this bug in their SFU?

They think it was caused by the Sun RPC driver. rpcxdr.sys

This crash looks like it was caused by the Sun RPC driver passing an invalid size to a system function. This driver needs to be updated or the dump sent to the vendor (Sun)

The size 0xdc is too large. Part of the function zeros the memory. The size was too large and caused a bad memory reference.

BAD_POOL_HEADER crash in rpcxdr.sys (jamesdavidhoward)

Thu, 18 Oct 2007 23:14:46 GMT

My Windows/XP laptop, w/ XP SP2, Services for UNIX 3.5 and ToolWorks 2.3 installed is suffering frequent BSOD crashes announcing BAD_POOL_HEADER and dumping memory. windbg claims the problem is in rpcxdr.sys (part of SFU 3.5 and the NFS functionality). A posting at http://forums.comodo.com claimed this is a conflict between rpcxdr.sys and some anti-virus product - probably one of the ones my company wants me to run :-). Anyway, is anyone aware of a repair for this, or a hotfix from MSFT regarding this?
