Issue

Browsing to Remote Desktop Web Access site (RemoteApp Programs page) Internet Explorer 11 users are greeted with warning message:

Browser Not Supported
This Web browser is not supported by RD Web Access. RD Web Access requires Internet Explorer 6.0 or later.
Vou can download the latest version of Internet Explorer from the Windows Update Web site.

Resolution

One way to resolve the issue is to add the RD Web Access domain to the client IE Compatibility View list.

Better approach is to fix this on the server side so there is no need to configure individual clients:

• Login to the Remote Desktop Web Access server and open IIS Manager
• Navigate to Sites > Default Web Site > RDWeb
• Double click on HTTP Response Headers
• Add a new Response Header:
• Name: X-UA-Compatible
• Value: IE=9
• Restart IIS
