I think this is DNS issue but cannot figured out what and how to correct
this, we built new DC for new remote site, sites are connected site-to-site
vpn all routing is working ports are open between sites. New DC was built
with temp IP from HQ range location once moved to remote site new IP was
assigned, all DNS records were updated with new IP, DC was moved to its own
Site in AD topology, replication between sites works, local PCs and servers
in this remote sites are authenticating against new DC, DHCP is working, DNS
on this DC technically works as well meaning nslookup works as expected.
There are 2 visible issues which makes me believe there is a problem with DNS:
1. cannot join to domain any new workstations or server in remote site
regardless if they get IP from DHCP or static
"The following error occurred atempting to join the domain: <domain_name>:
The network path was not found"
2. if I open MMC on this particular DC in remote site and try to add other
DNS servers to MMC all works, but if I try to add this DC's DNS to MMC in our
HQ site I get this message:
"The server is unavailable. Would you like to add it anyway?" and it cannnot
be manage from remote location
same thing is I try to open Active Directory User and Computers and connect
to DC in remote site I get:
"The following domain controller could not be contacted: <DC_name> The RPC
server is unavailable"
any idea what I'm missing here?
