APPLIES TO


 * Microsoft Exchange Server 5.5 Standard Edition

This article was previously published under Q314588



SYMPTOMS
When you attempt to perform an Exchange Server-aware backup against a clustered Exchange Server installation (one with two or more network interfaces), the backup software package may fail to communicate with the Exchange Server installation, and you may subsequently receive any of the following error messages:

RPC_S_SERVER_UNAVAILABLE

-or-

0x6ba

-or-

1722



CAUSE
Although you can specify and create additional IP address resources within the Cluster Administrator, Exchange Server binds only to a single IP address resource. As a result, Exchange Server does not register its remote procedure call (RPC) endpoints for these additional IP address resources and/or interfaces. Therefore, you may receive an error message when you attempt to perform Exchange Server operations against these additional network interfaces.
