Everything was working fine until about 2 months ago.
I have a Windows 7 system that I access with Remote Desktop Connection from a Windows 10 system. One day I found that my user account, which had been given administrator rights quite some time ago, couldn’t log on remotely. The Windows 7 system was configured for remote access with the setting “Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)”. When I tried to log on, I got an error stating “The Local Security Authority cannot be contacted”.
If I configured Windows 7 to “Allow connections from computers running any version of Remote Desktop (less secure)”, then I could log in but I didn’t want to use this less secure setting.
Doing some experimentation, I found that if I enabled the built-in Administrator account, then the Administrator could log in remotely using “Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)”.
If I created a new standard user called Test. I found that Test could also could log in remotely using “Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)”.
If I promoted Test to an administrator, then Test couldn’t remotely log on. He got the LSA error. If I demoted my account to a standard user then I could log in remotely using “Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)”.
When I promoted my account back to an administrator, the logon failed with the LSA error.
All users have valid passwords that are set to never expire and are members of the Remote Desktop Users group. The only thing that is changing is whether or not the users have administrative privileges.
Is this a permissions issue, or a behavior change cause by an update to Windows 7?
