Was working until recently.
When viewing the RDP session through a web browser it works both internally and externally h_t_t_p_s_://remote.company.co.uk/rdweb (links not allowed in post) and all the applications are shown.
When connecting to the URL: h_t_t_p_s_:_//remote.company.co.uk/rdweb/feed/webfeed.aspx (links not allowed in post) through the control panel applet remote app and desktop connections it works internally but not externally.
External clients get the error "an error occurred" and the event log shows error 1000 and 1007 and the event log says "following resource could not be downloaded, Error code: 0x8007007B, 0x0
Looked on TechNet and error doesn't match article, other articles suggest access denied.
If it were permissinons how is it available through other means or internally using the same credentials?
All services are checked and running, I have domain admin rights and assigned to all applications both on the gateway and the application.
Have been staring at this for days and so its probably something obvious I have missed.
thanks in advance.
