DNS - WAN

[kevin97]

Hello,

A friend of mine brought up a scenario to my attention today.

His company consists of two buildings in different cities. They have a WAN link established. He's unable to ping any hostnames from the building which is across the LAN. He can still connect to machines and email servers via I.P. The only workaround for him is using I.P's to communicate or manually editing the hosts file.

Anyone know where this problem may lie? I believe there's an issue with the local DNS server that he is using. If that's the case, what should he look for? Could this be a possible router misconfiguration issue?

Thanks

Without much information to go on, i see one possibility;

The two buildings DNS do not share the information between the two.

If the servers, whether they use the same domain names or not, don't share their information, one will not be aware of the other and its data. You could copy manually the data of one in the other, but that can lead to errors in the future. And why would you work so hard on making something manually when the system is able to do it automatically ;-)

He should look for either forwarders or zone transfers.
