After following these suggestions in regards to the whitelisting, I am still having difficulties with various users logging into an https:// webportal whose IP never changes. I have tried everything that I can think of in resolving this issue; however, I still cannot get these users to login successfully. The login screen seems to hang there and will never transition the user to the next screen. I have tried all of the wildcard suggestions, as well as, uninstalled the software multiple times over. I even deleted multiple registry keys that the software left behind, yet still after the installation and running the program again I get the same results. Advice?
