I'm having issues with DNS updates (local). Two servers,
one cable modem connection, DHCP from the router. Both
servers fail to update DNS records and then packets fly.
dropping the lan. Just did a clean build of my second
server to solve the issue, still have the issue.

Thoughts? This has got to be simple. But...
 
Use DHCP-server on the server. With setting options in Scope options (003,
006, 015 and if you still have W9x, ME or NT4-clients also 044 and 046
(0x8)) you can push all the necessary settings to the clients.

DNS on the servernics should *only* point to your server-IP. Check your
DNS-configuration and make sure it is only listening to the server-IP. The
ISP-DNS-numbers should be put in the tab Forwarders.

In some small shops I let the router manage the DHCP, but I've learned
my lesson. I find that a bunch of shops want to VPN into their servers
and it works best if you run DNS and DHCP on the server.

You can use Forwarding to get the people out to the internet - meaning a
DNS Forwarding.

When you point the DNS settings in DHCP for the clients, they only need
the DNS address of your local server - if the server is set for DNS
forwarding it will pass the query to the external DNS servers you
configure.

So, as long as your domain.name is configured for your server correctly,
then DNS should work. Make sure that you set your DHCP scope so that it
points at the server running DNS and NOT at the router.

Also - make sure that you are using a good domain name.
