SO we have a consultant that is configuring a database solution for us. He has access to the server through RDP but needs to be able to use SSMS on his local machine.
I have opened all the necessary ports on the configuration manager to allow remote connections. I have tested and it looks like (using packet monitoring) that my local machine can use SSMS and connect to the instance with a dynamic tcp port. I am NOT on VPN.
When the consultant tries, he gets the error "a network-related or instance-specific error has occured....error: 26....." After using packet monitoring, his machine is trying to connect through 1433 normal tcp port, but nothing is blocking it, and he still can't connect.
Is there any more set up needed on config manager to allow him to connect?
