How to handle DNS via root servers?

[kopja]

Hello everyone.

I do not know much about DNS so I am hoping someone will point me to the right direction.

Basically, last week, all emails sent from our server to a particular domain xyz.com came back as undeliverable.
After a lot of going back and forth, the issue was that
our ISP handles DNS for us, and they had been hosting xyz.com last year. Since last year, xyz.com switched to a different ISP, so their MX records changed.
In other words, my ISP resolved xyz.com to old-IP.

I solved this particular problem by creating a fwd lookup zone on my local server and manually pointing all requests to xyz.com to the right IP address.

Someone told me that I should be able to use smth called root servers and skip our ISP entirely for DNS requests.

Does anyone know how to do that?

Thanks,
kopja

Hi

You can disable forwarders on your local DNS. What type of DNS are you using ? ( BIND or Windows DNS )

We have a Windows server 2003 std ed, so I guess I am using windows DNS.

If I look at my DNS config, it shows as DNS forwarders 2 IPs (from my ISP).

So If I disable them, is there any thing I should be aware of?
What are the advantages/disadvantages to both?
