I have a Citrix WAN Client configured on an NT 4.0 workstation. Out of the blue that client can no longer log onto the Citrix Server. We get a message "the citrix server you have selected is not accepting connections". I can ping from the client to the server and vise-versa. We can successfully authenticate into the domain (green screen), just can't get to Citrix. This worked fine for several months. Any Ideas out there???
