The Microsoft® Exchange Server Analyzer Tool reads the following registry entry on global catalog servers to determine whether the TCP/IP Port registry key is set:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters\TCP/IP Port

If the Exchange Server Analyzer finds that the TCP/IP Port registry key has been created and is set, a non-default configuration message is displayed.

The TCP/IP Port registry key is required when a global catalog server needs to use a specific port for servicing MAPI clients. If you do not have such a requirement in your Exchange environment, you can remove this key.

  3. Right-click the TCP/IP Port key, and then click Delete.

  4. Close the registry editor.
