I have a customer that has this exact same problem. Sporadically it just refuses a connection. 9 times out of 10 they have to reboot their phone system if it is something that has to be done immediately and sometimes a few days later it will be fine. It seems like there is a process that gets the connection port frozen and either time or a reboot releases that connection. I know if you have enterprise services running on another computer that uses the "web programmer" it will do this a lot. I have never spent a lot of time with this because the Installed programmer works just fine and i disable that service when I have installed Enterprise Services. Unfortunately without a bunch of "All Error Logs/File transfer" and to pay Icon for their time, this problem will most likely not be resolved. Maybe time for an upgrade?
