  • On this network adapter, you enable one of the following features:
    • Receive Side Scaling (RSS)
    • TCP/IP offloading
Note After you install Windows Server 2003 SP2, these features are automatically enabled.

MORE INFORMATION
Depending on your OEM and on which IAG 2007 image that the server is using, Windows Server 2003 SP2 may be packaged with your installation of IAG 2007. In this situation, you should not experience the problem that is described in the "Symptoms" section. If you are not sure about whether Windows Server 2003 SP2 was packaged with your installation of IAG, contact your OEM or your reseller for more information about the image that you have installed.

Note If you are using IAG 3.6, the default image does not have Windows Server 2003 SP2 preinstalled.
