Hi
I am trying to establish a trust from a WAN domain to a domain on a LAN.
Network connectivity is established and confirmed.
The problem I am experiencing is that I cannot ping the domain name from the
domain on the WAN. I have configured forwarders on the WAN DNS and can ping
individual servers on the LAN domain, but not the domain name itself.
Eg. I can ping server1.contoso. but not contoso. itself
(To complicate matters, the LAN domain does not use RFC compliant naming; it
is called "contoso" (or "contso.", I am not sure of the difference). I don't
think that it is a problem as both are AD domains, but I thought it best to
point out.)
I suspect the problem is actually with the LAN domain itself, as when I log
onto the domain controller server.contoso. I cannot ping either "contoso" or
"contoso."
My question is, what records need to be present in DNS to allow me to ping
the domain name from the domain controller? In all our other domains, we can
ping the domain name, eg example.com or example.zone.
If run nslookup on the LAN domain controller ("server1.contoso") and enter
"contso" it returns non-existant domain, however if I enter "contso." then it
returns the IP address of the DNS server. This demonstrates that DNS is
somewhat working.
I understand that we will not be able to establish the trust until both
servers can contact a domain controller on the other domain by resolving the
domain name.
I hope someone is able to help.
Regards
Phil
