Hi,
I have Active directory domain with more than 200 windows server 2008 r2 and 400 windows 7 consoles joined to it.
I have made some changes in remote desktop security settings via group policy suggested by the security auditor.
The changes are:
1. Set client connection encryption level- High
2. Require use of specific security layer for remote (RDP) connections- SSL (TLS 1.0)
My all the Servers/Workstations are working fine after applying these settings, but in 1 Server i am getting this error "The connection can not proceed because authentication is not enabled and remote desktop requires that authentication to be enabled" when the policy is applied.
This particular server is Windows Server 2008 R2 SP1 VM Guest machine hosted in VMWare 6.0.0 Host. I have 50 more servers with same configuration as problematic one.
Can anyone help me resolve the issue, why the error is coming in that specific server and not in all other 199 servers.
I tried some troubleshooting steps suggested for the particular error:
1. Open regedit.msc and change "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ Terminal Server\WinStations\RDP-Tcp "set“SecurityLayer” to a zero.
2. I joined the server again to domain to refresh the configuration.
But nothing worked.
