I am an admin with over 100 PC's. I use RemoteDesktop daily on my local network, from PC to PC, PC to server and through VPN clients from home. I recently purchased a new PC from Dell, and am unable to connect to it using Remote desktop. Windows firewall is disabled, it's on the same LAN, same subnet, remote settings in Control Pannel are enabled. All PC's are running the same version of McAfee AV. When connecting to the new PC the "Configuring remote session" window opens, I check the box to allow connections to remote PC and then the "Configuring Remote session" window dissapears, no error. I have tried this from multiple PC's, all of them act the same. They can all connect to one another but not to the new PC. I have searched MS knowedgebase briefly, but though someone might have had the same issue here.
