Stupid DNS question...
Posted on 2002-07-09
I'll admit it, I know very little about DNS, I'm a DNS moron. I've always lucked out and had another guy on the team (usually a UNIX guy) who has taken care of DNS related issues. Well I don't have that luxury now, and I'm too lazy to look it up myself so I need some help!
I recently put up a 2k domain controller that is running DHCP, DNS, and a few other services. This machine has two NIC's in it, with the external access NIC being configured to use our ISP's DNS entries.
Before this server went up, every machine (workstation) here had a public IP address and was able to successfully resolve our POP server address which is hosted offsite: mail.ourdomain.com. Ever since I put our 2k DNS box up, mail.ourdomain.com is unreachable so I've had to resort to using the POP server's IP address.
How do I fix this and what exactly has happened here?
