The Best Practices Analyzer tool for Team Foundation Server queries a Windows Management Instrumentation (WMI) class (Win32_NetworkAdapterConfiguration) and determines the list of adapters for which the IPEnabled value is set to true. For each of these adapters, the tool retrieves the adapter information from the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}.
An error appears if the tool determines that the link speed of the network adapter is not set to automatically adjust based on the network speed. Network performance can drop dramatically if network adapters in multiple computers are configured for different link speeds. As a best practice, you should make sure that all servers are configured to automatically adjust to the network speed.
To resolve this issue, configure the network adapter to enable automatic detection of its link speed.
