I'm working with two new servers, both have Windows Server 2019 Standard installed. The servers are being added into a work environment that's never had servers before. I installed ADDS and DNS to SERVER-01 then promoted it to the PDC. That seemed to go perfectly. I installed ADDS and DNS on SERVER-02, but then when I attempt to add SERVER-02 to the new domain and promote it to BDC, I get an error message that says, "Server can't be reached."
I can ping SERVER-01 from SERVER-02, and ping SERVER-02 from SERVER-01.
The servers are on the same subnet.
SERVER-01 IP is 10.1.10.51.
SERVER-02 IP is 10.1.10.55.
I've tried turning off the Windows firewall but that doesn't help.
Any thoughts on why I can't add SERVER-02 to the domain that resides on SERVER-01?
Or why I can't promote SERVER-02 to a BDC?
