Microsoft Remote Desktop Services / RDS website Errors from a Windows 8 machine or a pc with Internet Explorer 10 or 11. You get the below 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
This is caused by Microsoft not releasing an update to 2008 to allow it to be accessed in the later browsers. In order to get it to work we can implement a workaround that forces machines with newer browsers to access the site as IE9 compatability view.
Exact cause is unknown, but this issue may occur if the user profile was manually deleted by using the command prompt or Windows Explorer by a user or by some program. A profile that is manually deleted does not remove the security identifier (SID) from the user profile list in the registry. Since the SID is still present, Windows will still try to load the profile by using the ProfileImagePath that points to a nonexistent path. Therefore, the profile cannot be loaded.
This can also be a issue with the user profile entering into a backup state, or if the C:Users(User Name) user profile folder is manually renamed.
