Are you trying to connect via an async connection? I could be wrong about this but I thought Citrix did away with async connections in MPS3.0 and above. This being said, you would need to RAS in to the network or VPN. From there it is just a local connection. But, guys please correct me if I'm wrong... DB Douglas A.
