I have been struggling with getting inter-site replication between
primary and secondary domain controllers. I installed the PDC and
everything is fine and working great in that office. When I got to the
second office, I brought up what was to be the secondary domain
controller. When I try to join it to the domain I get the following
error: An Active Directory domain controller for the domain example.com
could not be contacted. Ensure that the DNS domain controller is typed
correctly. If the name is correct, then click Details for
troubleshooting information. Then under details: The following error
occurred when DNS was queried for the service location (SRV) resource
record used to locate a domain controller for domain example.com. The
error was: "This operation returned because the timeout period expired"
(error code 0x0000005B4 Error_TOMEOUT) The query was for the SRV record
for _ldap._tcp.dc._msdcs.example.com. The DNS servers used by this
computer for name resolution are not responding. This computer is
configured to use DNS servers with the following IP addresses: IP of
PDC. Verify that this computer is connected to the network, that these
are the correct DNS server IP addresses. and that at least one of the
DNS servers is running.
Now I went back and first of all checked to make sure I typed the name
correctly, which I did. I made sure that I could query the DNS of the
PDC from the second site with nslookup and this works fine. I checked
the DNS records to make sure that _ldap._tcp.dc._msdcs.example.com
where in place, which they were. The DNS of the PDC is set to allow
updates, and I have even tried to set lmhosts on the SDC to reflect the
IP of the PDC. All of the necessary ports are open at both sites(tested
by allowing everything imaginable in) and forwards from the router are
set up correctly. When the SDC is on site of the PDC it joins without a
problem.
I have googled this for about 3 days and tried all kinds of thing found
there as mentioned in the above paragraph, and have even gone as far as
blowing both machines out and reinstalling to make sure there was
nothing weird that happened during install.
I cannot think of anything else. The DCs are both on cable modems and I
have talked to the Sys admin of the cable company who verified that all
ports are open and there should not be a problem on their end.
I am at a loss. The only thing I can even think of (though I'm not sure
that it should be a problem) is that we have the root domain DNS here
at our office for their website and we are using the real domain name
on the DCs at their sites. Is this an issue? If not can anyone lead me
in a direction that I may not have thought of or tried yet. Any help
would be greatly appreciated.
