We're in the process of incrementally upgrading our PCs to Windows 7, and several times now have been unable to open an RDP connection to the upgraded machine to remotely administer them. At some point we realised that Network Level Authentication was the culprit, and subsequently disabled it in the images we've deployed since.
This morning I had another machine that I could not connect to, having tried the following:
- Remote desktop via our RDS server (2008R2)
- Remote desktop into another Windows 7 machine on the same LAN/subnet & try opening a connection from there
nmap showed port 3389 not open.
The machine in question is several hundred kilometres away, so physical access is to perform a local login is somewhat difficult (and I'd prefer not to hand out the local login details to get the user to fix it).
"Group Policy" is non-existent for two reasons: the machine is not domain connected,
Since we're using FOG for imaging & management, it would probably be possible to deploy a registry hack or batch/powershell script to disable it; does anyone have any suggestions on a possible solution?
