I think this is once again an issue with the ports/firewall . All the required ports are not unblocked in rep's desktop. Before checking this, make sure that CAD is listed in the list of exception in firewall.
In CAD: TCP:65432; 59000; 59003; 59004; 38983;8088;59020; 59002;37606;59005 UDP 59500-59700
Similarly in case of CSD desktops, it's required to unblock the below listed ports: TCP 59021;59010;59012;59014;59016 59002,37606, 59005,59027 UDP 59500-59700
This is mandatory even though CAD or CSD is in the list of exception in firewall.
Note: Since you don't see this problem with other reps, looks like your(supervisor) desktop is okay.
