I have Win 2008 R2 server with remote access working, I have RDWeb working fine with RemoteApps. I want to enable external access, I've setup a public IP and the router is port forwarding 443 to the server IP and I can reach RDweb externally, but I can't load the RemoteApps - I get the error: Your computer can't connect to the remote computer because the web proxy server requires authentication.
I'm not sure what this means?
