I am running windows 7 and am having issues with logging into my CUPC client. It states that "Login Failed. Unable to connect to your login server". Some of the clients in my network are also having the same issue however a hand full of other clients work with no problem (leads me to think its client side issue). I have attempted to uninstall and reinstall the CUPC app and upon re-installation I find that the client has remembered my login info as well as login server Ip address. I would like to remove all files associated to CUPC and run a fresh install. Where can I find these files? I have run CCleaner after uninstalling to clear out registry info, but to no avail.
