new 2019 Windows AD server with an error running DCDIAG

I have to DC's now, one a 2012R2 (SVR1) and 2019 DC (SVR2). I've added a 3rd one called SVR2A. I am removing AD services from SVR1 because we are going to move it to a 2019 server down the road.

DCDIAG fails just on this one. Passes on everything else. So SVR2a also does not have the NetLogon folders because of this.

Testing server: Default-First-Site-Name\SVR2A 

  Starting test: Advertising

     Warning: DsGetDcName returned information for

     \\SVR1.mydomain.ca, when we were trying to reach SVR2A.

     SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE.

     ......................... SVR2A failed test Advertising

Any idea on how to fix this?

    Good morning, another update to this. That last error has now resolved itself and everything is now passing. The only thing left now is that both DC servers still think that SVR2a is a DNS server. I need to find out where this server exists and get rid of it. Also, just so I could pick out the server from any of the AD, after I demoted it, removed the services, I also renamed it to WIN2019SVR so that is why the name below.

    DNS server: 192.168.70.17 (WIN2019SVR) 

               1 test failure on this DNS server

           PTR record query for the 1.0.0.127.in-addr.arpa. failed on the DNS server 192.168.70.17               [Error details: 1460 (Type: Win32 - Description: This operation returned because the timeout period expired.)]
           Name resolution is not functional. _ldap._tcp.mydomain.ca. failed on the DNS server 192.168.70.17
