I have an IBM x365 server running Windows Server 2003 Standard. After applying Service Pack 1 I lost network connectivity. I can ping the local host and local IP address but I cannot reach any other nodes on the subnet or the gateway. Uninstalling Service Pack 1 brings network connectivity back. I thought that there may have been a conflict with my antivirus software (SAV 10) so I removed it and tied applying service pack 1 again, but the same problem returned, no network connectivity. I looked at the Windows firewall settings, and the service is disabled. Any suggestions would be appreciated.
