Here's my idea:

Set your domain up for primary and secondary name servers.

Have 2 DNS servers at your location; on on the T1(primary), one on the ISDN(secondary).

Use a firewall with 3 nics connected to each DNS server and the third to your LAN.

The firewall (Linux - modest box) uses NAT to translate to your LAN PCs.

Your PCs have 2 entries for the "gateway" in their config.

You now have 2 ways in and 2 ways out.

This is a simple plan and you should consult a "real" network engineer about the details. Feedback anyone? I only spent 10 minutes putting this idea together, but I think it's pretty sound.

T1----DNS1->|Fire|
ISDN--DNS2->|Wall|---> Lan, mail, etc.

Good Luck!

First you don't want to have the DNS populate quickly. You want to have two separate name servers running. That way if one is down, you can switch to the other one. If you look at some of the larger ISP's, you will notice that some of them have 4. Most all have at least two running all the time.

Network Solutions processes all of their changes at 5am and at 5pm EST. If you get your request in early enough they might do it that day. I have never found them to move quite that fast. Generally you send them the form to make the change, they send it back and says that it has errors on it. Then they sit on it until you email them which they ignore. I guess you can tell I am not one of their biggest fans.

Hope this helps.
