SYMPTOMS

Consider the following scenario:

  • You have a computer that runs Windows Server 2008.
  • A network adapter that supports receive-side scaling (RSS) is installed on the computer.
  • You enable receive-side scaling on the network adapter.

In this scenario, receive-side scaling may be disabled unexpectedly. Additionally, some TCP connections may be reset.

If you use the netsh int tcp show global command to query for the receive-side scaling status, you receive output that indicates that receive-side scaling is disabled. This output resembles the following:

Querying active state...TCP Global Parameters----------------------------------------------Receive-Side Scaling State          : disabledChimney Offload State               : enabledReceive Window Auto-Tuning Level    : highlyrestrictedAdd-On Congestion Control Provider  : noneECN Capability                      : disabledRFC 1323 Timestamps                 : disabled

Notes

Receive-side scaling helps improve network processing on computers that have multiple processors and high-speed network adapters. Therefore, this problem usually may be seen on computers that have 10-gigabit network adapters.

When this problem occurs, you lose the increase in network bandwidth that results from receive-side scaling.
