I have a problem joining a server in my DMZ zone to the domain . my configuration is as follows:
LAN : has windows 2008R2 DC with DNS service up and running
DMZ : has windows 2008R2 server configured to point to Windows 2008 R2 DC as it's DNS server
the firewall between them is Cisco ASA , I opened all ports from DMZ to Internal (for testing)
I can ping the DNS , but I can not resolve any DNS names .
I attached a schematic diagram illustrate my scenario
any suggestion ??
