Re: An Internal state error has occured - RemoteDesktop
@MD2020 What do we see in the user access logs and policy trace events for terminal services?
Internal state error occured will be displayed if the ACL present on the VPN is not permitting the traffic or other errors (Microsoft errors) being presented when connecting which would be shown as the generic "Internal error occured".
If we configure L3 access for the same RDP resource, is it working from the problematic user machine?
I have seen issues specific to local user machine as well user account, so it is good to check if other users can access the same RDP resource (non-working) using their credentials and the affected user can login to other RDP resources which were working for the other users.
