Most desktop RDP systems are single user. So it has to drop one to service the next.
That is, unless you are running Windows Terminal Server.
Hello, I have a PC in one of offices that is located on LAN (ip 10.2.1.1) and I am RDPing from PC on network 10.1.1.1. All works ok, until destination PC connects to Dial-up for one of the programs. I lose connection to pc from remote office, but still able to connect from any PC on same subnet. How can I resolve the issue and be able to connect from both offices?
