Hello,
The following error, an authentication error has occurred The local security authority cannot be contacted, appears when domain users, who have historically connected successfully using RDP, attempt to connect.
About the same time, user shares on workstations can not be accessed from other workstations. A similar error appears, saying the computer is not accessible, logon failure: the user has not been granted the requested logon type at this computer. The shares on the servers are accessible, as always.
One domain account, however, shows none of the symptoms. This account is in the domain local group administrators, but not in the group Domain Admins.
I have carefully compared the working account with the other accounts on the network, and cant find a difference that would break RDP.
I created a new user account and added it to the same group accounts as the working account. The new user account cannot connect.
One change to the network is that one Ethernet switch was replaced, but if this or the router has problems, that would affect all users.
DNS seems ok; the windows clients are not registering with DNS, but this problem has been around for while; typing the IP address into the RDP screen had been the workaround.
I have tried changing the setting in System Properties, from Control Panel, System, Remote Settings, to allow connections from computers without NLA, after reading some of the forums.
Any ideas? User Rights?
thanks,
