Phillip, Your Microsoft DNS setup is incorrect for internet usage. I'd strongly recommend that you look at Microsoft Knowledge Base Article Q300202 - Configure DNS for Internet Access in Windows 2000.
The article will explain that you must remove the root domain (the "." zone) and then you can configure forwarders. You should also read Q174419 - How to Configure a Subnetted Reverse Lookup Zone on Windows NT. If you're going to run your own DNS's for e-mail, you'll have to provide Reverse Lookups (PTR records) to keep much of your mail from being rejected. Since you are so insistent on being able to make your own changes to your DNS, I would also suggest that you investigate running the Primary DNS for your domains and have your ISP secondary for you.

Sandy, I guess I don't understand how my server can be working fine for nearly two years and yet have its DNS "hosed". If being "hosed" is so bad, then how is it that the server has been running fine for 2 years? This "unknown host" issue happens less than 0.001% of the time. > This hosing usually happens during original setup of Windows 2000, if > you don't have a connection to the Internet and don't indicate as such > to the setup program.

Things worked fine one the box got to the server farm and we hooked it up. > IMail's settings, if present, will override Windows'.

How does one stabilize one's service provider's upstream DNS servers?
