Ghost 15 -- connecting to agent

I am trying to connect to the already installed agent on a client PC from my server where full Ghost install is located.  Both PC's are XP sp3.  Both on the same LAN.

 

No matter what I try, I keep getting message that I must provide valid credentials, which I've been doing.  I even shutdown the firewall on both machines to get that out of the way.  And, the login I am trying to use has full admin rights.

 

Ideas?

 

Thanks.
