Microsoft have recently released Internet Explorer 11 to the wild for Windows 7. Unfortunately Microsoft haven’t released an update for 2008 RDS so users who visit the site will see the error :
Browser Not Supported - This Web browser is not supported by RD Web Access. RD Web Access requires Internet Explorer 6.0 or later. You can download the latest version of Internet Explorer from the Windows Update Web site
I published a guide on what can be done to the 2008 RDS server to make it work a while ago
There are workarounds for the client but why fix the issue for 1 user when you can fix it for everyone 🙂
