Does anyone know of a utility that would allow me to monitor RPC over HTTP connections to our front-end server. I need to get an idea how many people are using the service. Is there a way to tell?? -Patrick

You can review the IIS log files and look for the /Rpc /RpcWithCert target.

The only problem with that is if I have mobile office users hitting this server they will show up with that log entry too, won't they? -Patrick

Every client who connects through Outlook Anywhere (formely known as RPC over HTTP) will be logged in the IIS logs. I've mistaken with folder name you should look for. The Microsoft-Server-ActiveSync is being used by Exchange ActiveSync devices but you should look for /Rpc or /RpcWithCert (depending on your setup).

Thanks Andrey!
