The Rpc_Binding_Order registry entry is present
Topic Last Modified: 2005-11-18
The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to check for the presence of a client-oriented remote procedure call (RPC) binding order registry entry on the Exchange Server computer:
If the Exchange Server Analyzer finds the Rpc_Binding_Order present, a warning is displayed.
If the Rpc_Binding_Order value is present, it indicates that one or more of the following is installed on the computer:
Exchange Server version 5.5
Microsoft Office Outlook® 2003
The RPC_Binding_Order entry determines the protocol sequence that is used when Outlook RPC communications are initiated. This entry is not created in Exchange Server 2003 or in Exchange 2000 Server. This entry is only created in Exchange Server 5.5 and in earlier versions of Exchange. If Exchange Server 5.5 or Microsoft Outlook were previously installed on this computer and have since been removed, you can manually remove this registry entry. In addition, you should remove Outlook from any computer running Exchange Server, as that is an unsupported configuration. For more information about running Exchange and Outlook on the same computer, see the Microsoft Knowledge Base article 266418, "Microsoft does not recommend installing Exchange Server and Outlook on the same computer" (http://go.microsoft.com/fwlink/?linkid=3052&kbid=266418).
