Server no longer communicating on a network

I have found a strange issue with serveral Win2K3 servers while applying SP2
or other hotfixes. Once the SP/hotfix has been installed and the server
rebooted, it can not ping out or respond to a ping. It appears the patch
cable has been removed. We have found the following solution but I am trying
to find the root cause:
Go into services, select Remote Procedure Call ( RPC ) not ( RPC ) locator.
Right click, properties, select the log on tab, select local system account,
also check the box allow service to interact with desktop and reboot the
servers.

Any input would be appreciated.

I'd recommend disabling some of the "extras" that were added by SP2. The
three problem ones that have become somewhat "famous" are EnableTCPA,
DisableTaskOffload, and EnableRSS. They are found in the registry at:

HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Param eters\

Some may already exist, some you may have to create.

They are all DWord Values

EnableRSS=0
EnableTCPA=0
DisableTaskOffload=1

Probably want to reboot everything after that.

If that doesn't work you can always put things back like they were.
