SYMPTOMS
After you upgrade a Microsoft Exchange 5.5 server in your Exchange 5.5 site to Microsoft Exchange 2000 Server, e-mail flow between a remaining Exchange 5.5 server and all Exchange 2000 servers stops. E-mail flow between the Exchange 2000 servers continues without interruption; only mail to and from the remaining Exchange 5.5 server is affected. If you view the Event Viewer Application log on the Exchange 5.5 server, you may find events similar to the following

Event Type: Warning

Event Source: MSExchangeMTA

Event Category: Interface

Event ID: 9318

User: N/A

Computer: Exchange5.5ServerName

Description: An RPC communications error occurred. Unable to bind over RPC. Locality Table (LTAB) index: 6, NT/MTA error code: 1753. Comms error 1753, Bind error 0, Remote Server Name Exchange2000ServerName [MAIN BASE 1 500 %10] (14)

where Exchange5.5ServerName is the name of the Exchange 5.5 server.

RESOLUTION
To resolve this issue, follow these steps:

WARNING: If you use the raw mode of the Exchange Server Administrator program (admin /r) incorrectly, serious problems may occur that may require you to reinstall Microsoft Windows NT Server, Microsoft Exchange Server, or both. Microsoft cannot guarantee that problems that result from using raw mode incorrectly can be solved. Use raw mode at your own risk.


 * 1) On the Exchange 5.5 server, start the Exchange Administrator in raw mode. To do this, click Start, and then click Run. In the Open box, type drive:\exchsrvr\bin\admin.exe /r (where drive is the drive on which Exchange is installed), and then press ENTER.
 * 2) On the View menu, click Raw Directory.
