Welcome back to the same bat time, same bat channel. We recently migrated SiteManager over to a new 3.18a version and to our new enterprise Citrix farm. Almost everything work perfectly, except that it didn’t. We ran into some fun with a single port. SCCP. Not sure if it is using SCCP or just port 2000, but it stopped some functionality. So if you have your DPS server on a different subnet, make sure to have this port open!
