Windows 2003 SP2 Issues

After you install service pack 2 of windows 2003 you face a lot of issues. I am not going to list out them. I am providing you what to do immediately after installing SP2 to resolve the issue.

Please keep these few points in mind while dealing with SP2 SNP issue and referring KB 936594:



The package provided in this article doesn’t work with x64 OS.
This package is disabling the RSS, EnableTCPA and chimney offload.
In the workaround, it is not mentioned to disable chimney offload but we need to do it by modifying the value of ‘EnableTCPChimney’ to 0.
Since, it is a part of SP2 which is causing these issues; you might feel like blaming the SP release. It is better to gain some knowledge on SNP and share the document with your colleagues. Also, we need to know that it is more because of the hardware why these features are not working.

I addtion to what is given above also try out the following chages:

+ Check the nic card properties and make sure the drivers are updated.
+ Disabled checksum offload and jumbo frames.

If you still see the issue please make the following registry changes.
