Windows Server 2003 Service Pack 2 and the Scalable Networking Pack

Remember all the heart ache we had with this … and having to disable TCP Chimney just for the server to actually stay working :-|

 Wel Michael has found the latest installment in the way of a new KB that essentially sets EnableTCPChimney, EnableRSS,and EnableTCPA to 0

948496 An update to turn off default SNP features is available for Windows Server 2003-based and Small Business Server 2003-based computers

What is interesting about the KB is the list of issues that may occur when Windows Server 2003 SNP is turned on!

  • You cannot create a Remote Desktop Protocol (RDP) connection to the server.
  • You cannot connect to the Exchange server from a computer that is running Microsoft Outlook.
  • Inactive Outlook connections to the Exchange server may not be cleaned up
  • You experience slow network performance.
  • You experience intermittent RPC communications failures.
  • The server stops responding.
  • The server runs low on nonpaged pool memory

Not to serious then!
