I have Windows server 2008 (not R2) server running RD gateway and now finding that any client that has upgraded to windows 8 can longer connect via the RD Gateway server. We are using domain\username to log in as we have always done with windows 7 RDP client (which just worked). After reading a number of posts where certain "fixes" or "workarounds" have worked sadly none of these appear to apply to our setup.
I have made sure that ignore client certificates is set to ignore and restarted IIS, I have chacked the server logs and there are no failed logon events, in fact the authentication succeeds but the session isn't created.
Running out of ideas now...any help?
