I am at a loss. Here is what I have going on:
On the SQL server when I run portqry is says it is listening
On the SQL server, the firewall is disabled for domain connections
On the workstation, I can ping the SQL server by name
When I run portqry on the workstation, it says filtered
The only thing that changed was adding a new 2019 server as the primary DC that now holds the FSMO roles.
