I have a new install of 5.1(3) on a single server. I have been doing all the configuration from a Firefox window, so I do not know how long the issue I am about to described has existed. Anytime I try to log into the Call Manager administration web page using IE, I get a "Login Failed, Please Try Again" error. But I can turn around and log in through a Firefox browser with absolutely no problems. I ensured that there were no LAN settings in IE and I have cleared everything possible.
Thanks in advance.
