NC373i - Multifunction NICs Experience Slow Performance with TOE RSS SNP


After installing Microsoft Windows 2003 with Service Pack 2 (SP2) or Microsoft Windows 2003 Scalable Networking Pack (SNP) on a server that has TCP/IP Offload enabled, you will experience network communication issues.

The following list includes a few network-related issues that the server may experience:

  • Remote Desktop Protocol (RDP) cannot be used.

  • A client cannot be joined to a domain.

  • The server cannot connect to the Exchange server.

  • Network performance is slow.

  • Network performance is slow when communicating with a Microsoft Windows Vista system.

  • Performance is slow when logging to the domain.

  • Intermittent RPC communications failures are experience.

  • The server stops responding.

From the Network Configuration Utility, disable TOE and RSS.
