Our two sites each have 2K3 domain controllers with AD integrated DNS. Let’s call the sites Detroit and Lansing with the DC’s named DET-DC1 and LANS-DC1, respectively. WAN connection is a simple T1 with flow control or firewalls.
Both sites are on the same domain (let’s call it DOMAIN) with no ‘.local’ or ‘.com’ suffix.
At either site I can ping local workstations by name just fine. I get errors when I try to ping remote PC’s by name. Pinging PCNAME or PCNAME.DOMAIN gives me the same result. Pinging by IP works fine.
I can add a PC manually to the lookup zone it will replicate properly across the WAN allowing me to ping the PC by name.
