Endpoint Protection

I have 2 systems connected via Cross-over cable, both are Server 2008 R2 with SP1 and the Hyper-V role enabled. When I attempt to transfer 20+GB of data through this Gigabit connection the recieving computer will often blue screen and reboot. Both are running Endpoint Protection 11.0.6005.562.

I contacted the hardware vendor thinking it was related to an expansion network card but they pointed me back to Symantec as the cause.

the stop code i get is: 0x0000007f (0x0000000000000008, 0x0000000080050033, 0x00000000000006f8, 0xfffff80001a8429e). and the Crash dump points back to tcpip.sys.
 

any suggestions?

What is the version of tcpip.sys?

TCPIP.sys file version 6.1.7601.17514 I'll investigate the links you provided.

thanks!

Does the issue occur when SEP is disabled? If so, what features are you running on the client?

Acquired the hotfix, I attempted to apply it to my test machine which was experiancing the problem but it says it is not applicable.

I attempted to run it for the production machine which was experiancing the problem and it was willing to apply the fix.  If i can schedule down time i'll test iton the production machine

The issue occurs with SEP disabled (it was disabled to increase throughput of known good files)

the installation includes:

Antivirus and Antispyware

Network Threat Protection

and Application and Device Control.

it does not include:

Antivirus Email Protection

TruScan Protection.

Also: I believe our Support Contract with Symantec is current.

If the issue is happening with SEP disabled, then it is likely that SEP is not the cause of the BSOD.

Have you ran scans to make sure the system is not carrying a virus?

Yes, I've run scans on all impacted systems - all scans come back clean.

if things go as planned I'll be able to test the hotfix tonight, but that depends on scheduling issues.
