Use RPCTest to Detect Communication Status with Microsoft Exchange
Cisco Unity uses RPC in order to determine if it can talk to the Microsoft Exchange server. The RPCTest tool uses this functionality to help troubleshoot communications problems between the two servers.
Run the RPCTest Tool on Unity from the Command Line
This procedure describes how to use this tool in order to detect if Microsoft Exchange server communicates properly with Cisco Unity using RPC.
Complete these steps in order to run the RPCTest tool:
On the Cisco Unity Server, go to Start > Run, and type cmd in order to bring up the command-line window.
Change directories to x:\CommServer\Utilities\Customer Support Tools\RPCTest\.
Where x is the drive letter where Commserver is installed.
Run this command:
rpctest -s exchangeservername
Where exchangeservername is the name of your Exchange server that Unity claims does not respond.
The results of this command show you whether the server is on line or off line.
This output shows the server on line.
This output shows the server off line.
