      DC on site A.
      Clients on site B can ping DC, can browse SMB shares but cant join domain. DNS requests to DC from site B time out sometimes. When site B router is set as DNS forwarder to DC, there are no DNS timeouts but still cant "contact DC" even though I can ping and resolve FQDN. Help please….

        There are multiple ways of solving this issue assuming it's DNS related.  Some solutions are more efficient than others, but let's say your domain is example.com:

        • Leverage the DNS forwarder and add example.com to the Domain Overrides.

        • Configure a DNS server on site B.  Add a conditional forwarder for example.com that is pointed at the DC on Site A

        • Configure a DNS server on site B.  Add a primary forward zone for example.com and create an "A" record for example.com and point it at the DC on Site A

        • In theory, you could also do this -> While option 1 is in play (or add example.com to the hosts file here), Spin up a Server on Site B, join the domain, promote this server to a backup domain controller.

        • Add example.com to the hosts file on every machine in site B.  (A management nightmare and the most inefficient method, but will work)
