Remote desktop certificate error - how to connect anyways?

Solution 1:

Use with caution (as per Microsoft): There is a registry entry you can enter so this will go away: HKEY_LOCAL_MACHINE - Software – Microsoft – Terminal Server Client Add a new DWORD called AuthenticationLevelOverride and set its value to 0.


You can also push this out via GPO: Open Group Policy Management and create or edit a Group Policy Object Under computer configuration - Preferences - Windows Settings - Registry Right click and create a new registry item:

Action: Create
Key Path: SOFTWARE\Microsoft\Terminal Server Client
Value name: AuthenticationLevelOverride
Value Type: REG_DWORD
Value data: 00000000


Solution 2:

You can use mmc to accomplish what you need since the snap-in works on remote computers. See: The caveat to this is that you need another Windows Server computer handy to use this snap-in, and working over the network is questionable if the firewall blocks a lot of things.
