I've assited endusers installs Citrix Cllient over the phone countless times prior to XenApp. Typically these are home computer users. I walk them through the client install - add a ICA and off they go. Now I can't get past the Server Name. Particularly on Vista Home computers. They get the error about can't find any Servers. Changing protocal type has no affect. Guess I don't undrestand something because there is no server to connect to untill they actully run the ICA Client connection. I've been keeping an old version of the Client install around to get around the issue but that's not really a solution.
