I have a remote Windows 7 Enterprise SP1 system (32 bit). It has two monitors. I have two callback connections created on the Host calling back to my home through an open port in my home firewall. I use each connection for one of the monitors. This scenario works fine.
Every so often, one of the two connections will show as Offline and I am unable to connect to it. The other connection is up an running just fine. If I were running a single connection, I could easily blame it on the network somewhere. But, in this case, I have one connection working and the second not working and both are same source/destination. I have tried forcing it to do the callbacks, but the only thing I have found that fixes this scenario is to restart RUT Host.
An issue that seems to occur when I restart the host to try to get both callbacks to come up, I sometimes don't seem to be getting dual monitor support on each connection. It shows me both monitors in one window with no option of selecting monitor 1 or 2. The host icon keeps disappearing during all of this.
Also, when it had the problem this morning. I tried the restart host option and waited but the connections never came back up. I had to jump in with another software and manually stop the host and kill the processes for it. After tha, both connections came back up in the callback, but then the issue mentioned above happened.
I finally ended up restarting the computer to fix everything.
