User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID: 20160421124000 Steps to reproduce: From my Windows 10 local computer, I routinely remotely log into a computer running Windows Home Server 2011 OS. After I connect with the server, I then remotely log into one of the computers on the server local network. Actual results: I get the popup window from Microsoft: "This function is supported only by Microsoft Internet Explorer.This Web site needs to run the following add-on: Remote Desktop Services ActiveX Client. The add-on is currently not turned on." Expected results: Formerly I could successfully log into the computer. I did this by using various versions of Internet Explorer emulators, such as IE tab v2, or Fire IE 0.4.6.1, and this worked fine. But now none of these emulators seem to work, and now I can't even install some of them. The remote login still works from another local computer with an earlier version of Firefox, using Fire IE 0.4.6.1.
OK....Don't know what I did right, but now IE tab 2 (version 126.96.36.199) is once again working! So this was sort of a false alarm. But something was not right, and now I don't know how I fixed it, but I did. Hope that others don't have this problem. Sorry for the misleading bug entry!
