problem in domain lookup for a particular domain
i've got a strange problem. there is a domain name eg. xyz.com i cannot resolve it through my dns but can be resolved from other opendns. my dns can resolve all other domain hosted on the same server but not this particular domain. whenever i restart the service it works for limited time, but again same problem both from primary and secondary dns. if the dns resolve xyz.com, it doesn't lookup to its www & mail or vice versa. i am very confused on this matter and got no idea what is goin on. please help!!!
