I have run a BPA on my SBS 2011 server and noticed there is the below error.
When you try to browse the web through Remote Web Access (RWA), you receive an "HTTP Error 403.1 - Forbidden" error message
Start IIS Manager, expand Default Web Site, and then expand the Remote virtual directory . In Features view, double-click Handler Mappings, and then in the Action pane on the right, click Edit Feature Permissions. Click to select the Read and Script check boxes, and then click OK.
I have checked IIS as mentioned and it has Read, Script & Execute enabled. (see bellow)
Should Execute be enabled?
Look forward to reading your comments!
