The error message from the agent log indicated that there is a connection problem between the agent and the manager. Test that a telnet connection from the agent to the manager on port 22001, which is the default port for media service, is successful.
Resolving the problem
Check the window hosts file on the manager to see if the host name is specified. It should be in this format:
where xx.xx.xx.xx is the IP address of the manager, host.name.domain.etc is the DNS host name.
The hosts file is located at C:\WINDOWS\system32\drivers\etc
If the host name is not specified in the hosts file, you need to use the IP address instead of the host name in the agent configuration tool on the agent system.
