I just recently trying upgrading the computers in my network from UltraVNC 1.0.8.2 to 1.2.0.1 and some of them work fine but others that we use to connect over a VPN have been connecting after password is entered and then it acts like it is about to connect but then just disconnects and closes the UltraVNC window.
I did install this version by using a patch management software to deploy the needed files and ran a batch file to silently install the UltraVNC after also using a batch file to run the uninstall executable that was found within the UltraVNC folder.
Any clue why it would act like is connects but then disconnect right away?
