I have a company and have my domain hosted by a company in
CA. I installed exchange 2000 on my systems and now have
issues configuring DNS to resolve my domain name. I called
the company hosting my domain name and they gave me the
DNS IP that resolves the name of my domain. I need help
configuring the whole Network as mails can not be sent by
any of the computers on the network.

If you want all incoming mail sent to you Exchange server You need three
things to happen in your Public DNS.
1 In your public DNS zone, you need first a host record pointing to a Host
named "mail" (or whatever) give that host the Public IP that can be
forwarded to port 25 of your mail server's address.

2 In your Public DNS zone you need an MX record leaving the host or domain
blank and give the FQDN of your mail server, i.e. mail.domain.com.

3 You will need a PTR record for your mail servers Public IP address
pointing back to your mail servers FQDN.
Your ISP can do this for you because they usually own the public IP address
you use.

If you are using a "Smart host" (another mail server on the internet that
will be used as a relay) that Exchange will be sending mail through then you
need not worry about the reverse lookup. But you will need an SMTP connector
for the smart host see: 265293 - How to Configure the SMTP Connector in
Exchange

On your Internal DNS server you only need a host named "mail" with the
internal IP address of your mail server. This allows internal clients to
find your mail server by name. Also, Exchange 2000 must only use you local
AD DNS server because this is how it connects to the Global Catalog.

Ooops,
I just notice you are using a cable modem. You have to use the smart host
and probably will have to set exchange to go get your mail from a relay read
