How to: Configure a Network Adapter to Automatically Adjust Speed
When a client computer is not configured to automatically adjust the link speed of its network adapter, some Team Foundation functions might take a long time to finish. Such functions include creating team projects, saving work items, or merging code changes. In some cases, these functions might never finish, and an error message might appear that contains the phrase "The underlying connection was closed."
The speed with which Team Foundation functions finish depends, in part, on the speed of the computer network. The configuration of network switches and your computers' network adapters can affect the network throughput. For example, "autosense mode" or "auto-negotiation" might be turned on, and information might be transmitted in either full-duplex mode or half-duplex mode.
To minimize the time required for Team Foundation functions to finish, you should confirm that these settings are set appropriately for maximum throughput. For more information how full-duplex mode differs from half-duplex mode, contact the network administrator.
Note
If you use a multiple-speed Ethernet network adapter for cluster communications, see "The effects of using Autodetect setting on cluster network interface card" in the Microsoft Knowledge Base.
