The Microsoft® Exchange Server Analyzer Tool queries the Win32_NetworkAdapter Microsoft Windows® Management Instrumentation (WMI) class for all network interface cards (NIC) that are bound to the TCP/IP protocol.
The Exchange Server Analyzer then queries the following registry branch to determine whether the TeamAdapters key exists for those adapters:
If the Exchange Server Analyzer determines that the TeamAdapters key exists for one or more NIC on the server that is being analyzed, the Exchange Server Analyzer displays a warning.
This warning indicates that NIC teaming is enabled on the Exchange server that is being analyzed. Although NIC teaming is generally not a mail flow issue, care should be taken to make sure that teaming is configured correctly with the most recent NIC drivers available.
To address this issue:
- If mail flow issues occur on the server that has NIC Teaming
enabled, temporarily disable Teaming to see whether the mail flow
issue is resolved.
- Update the NIC drivers to the latest available from the NIC
- Strictly follow the Teaming configuration recommendations of
the NIC manufacturer.
