I have a client with an small AD infrastructure. The previous IT person made amess of things. In any event, two of their computers are refusing to allow connections even thought file & printer sharing is allowed in the firewall rules and logged on as the local administrator.
The computers can connect to all over shares and computers but nothing is allowed as a connection to these two machines.
I have tried everything I could think of to fix this issue. Removed and added the computers from the domain etc.
