I have a Windows 2003 TS behind a firewall. I have built a new RDS licensing server (with a different IP than the original Windows 2003 TS licensing server) and I don't recall the ports we had to open on the firewall to allow CAL checkout to happen. Could someone let me know what ports need to be opened so that I can have my FW team open those ports to the new license server?
Also - does just the TS need these ports, or do clients also behind the FW need these ports open as well. In other words, does the TS request the CAL on behalf of the client, or does it just tell the client "where" to get the CAL and then the client has to make the request (and hence will need to have the ports open too).
Thank you
