Details

Explanation

This Error event occurs when Microsoft Exchange tries to register the remote procedure call (RPC) endpoints of the server on the TCP/IP, RPC/HTTP, or LRPC protocol stacks. This event occurs when Microsoft Exchange starts, and only if the protocol stacks are supported by the server.

If Exchange fails to register the RPC endpoints by using any of the protocols, Error event 9691 is logged.

Additionally, if Exchange uses the TCP/IP or RPC/HTTP protocol, the Exchange store process starts. If Exchange uses the LRPC protocol, the Exchange store process does not start.

Error event 9691 is not logged if a protocol sequence does not exist on the server. For example, a failure to register the RPC endpoints of the server by using the RPC/HTTP protocol does not trigger this Error event if RPC/HTTP is not supported on that server. This Error event should not occur during typical operation.

User Action

To resolve this problem, inspect the operating system on the server on which the failure occurred. Also inspect the Exchange server.
