First thing you want to do is make sure that the media server can communicate with the remote agent on the remote server.
1. Open a command prompt on the media server
2. type in "telnet REMOTESERVERNAME 10000" (without the quotes)
3. You should get a bunch of ascii characters if the connection is successful.
If you get a connection refused or it's unable to connect, check your firewall settings or if anything is blocking the port.
You can also check to make sure that the remote agent is listening.
Open a command prompt on the remote server
type netstat -a
Make sure that you see port 10000 as listening
