So i have been having this issue for a long time. I have multiple Junipers running multiple versions of the code and the clients are windows xp, 7 and 8. 32 and 64 bit. Some computers just keep disconnecting from termianl sessions even after completely removing all juniper clients and reinstalling them. I am RDP to the same computer from one computer it works longer and the other computers it keeps disconnecting every few seconds or minutes (randomly). This is driving me nuts. I am going to open a ticket on monday but i thought i ask here first.
unfortunately, it looks like you may have found a new issue that we are not aware of (and that port you specified is only for the server, right? You don't have a client port specified?)
i am using the same bookmark from diffrent computers. and i am using the variable and have also tried putting in a static username in the bookmark. I am specifying 3389 as the port.
there is no error message it works and then the screen kind of freezes and then it says retrying atempt 1 of 20 and it connects on the first attempt but it keeps freezing up and dissconeccting.
