Once in awhile someone will disconnect from RDT and max out the number of connections. What do you do about this reboot the machine has been the rapid answer. Here is a little trick I picked up.
cmd
mstsc.exe /v:xxx.xxx.xxx.xxx /console
Just put in the IP address of the machine you are trying to connect represented by xxx.xxx.xxx.xxx. You will then mount the machine as the console connection and be able to release or reset other connections.
