I am in the process of setting up a server with Windows 2000 Server and Citrix MetaFrame Presentation Server 4. For unknown reasons the Comtrol products do not work with the latest version of MetaFrame Presentation Server via async connections. Is anyone working successfully with the Digi products and the latest version of Citrix MetaFrame PS4? I have ordered a Digi AccelePort RAS 4 PCI 4 Port Multi-Modem adapter already but I am hoping for some input from other users regardless. Much appreciation.
