Hi, I have a windows 2008 server serving as DC, installed DNS everything is fine. Consider the domain name as corp.mydomain.com If I go to the command prompt and typed ping x, I'll get a reply from x.mydomain.com I feel that there is something wrong with it, what do you suggest ? please note that I had configured the ISP DNS as a forwarder. My dns "Zone Name" is 100% corp.mydomain.com and my primary server is servername.corp.mydomain.com and the responsible person is hostmaster.corp.mydomain.com, I do have 2 name servers servername1.corp.mydomain.com, servername2.corp.mydomain.com my zone type is active directory-integrated primary thanks in advance
