I have a user that is attempting to remote access their business network through an approved URL site. Once at the site they log into their workstations and thus have a remote desktop environment. This user is getting and error that states: "An error occurred while sending data to the Remote Desktop Gateway server. The server is temporarily unavailable or network connection is down. Try again later, or contact your Network Administrator." Attempts to access the remote pc included turning off the firewall and the AV program, restarting DNS and DHCP, clearing out the DNS cache, deleting the cookies and temp internet files and rebooting the system. Any thoughts?
