I don't know if this is the correct forum or not, but here goes:

Have any of you experienced this defect?

We have found what we believe to be a defect with the Windows Server 2003 Standard Edition OS.

Problem: TCP Resets

Our monitoring specialist along with our Cisco CCIE have determined that we have servers that are "machine gunning" out 3 rapid TCP resets at a time randomly.

After a lot of testing we have found the following:

On clean builds:

Server 2003 Standard Edition SP1 no problem
Server 2003 Standard Edition SP2 no problem
Server 2003 Standard Edition SP2 fully patched tcp reset problem

This appears to be a true defect.

We have numerous (a LOT) of our servers that have this issue right now.

It would seem logical that an update post SP2 is causing this, and it is a real problem.

See attached pic.

Thanks,

Michael

Hi,

That sounds like this KB http://support.microsoft.com/kb/923200 , maybe cross checking your tcpip.sys file will tell the story.

By chance is this server behind a Cisco ACE Load Balancer?

Yes,

This one does look like it needs an engineers attention, I always say if your doing a packet trace then it's probable an ugly one.

Mike
