Internal domain name conflict

I help out with a non-profit org that is having trouble viewing their
website(which is hosted by another company) internally on their system. I
know the issue is that they named their internal domain companyname.com
instead of company.local, and their website is www.company.com. So of
course the DNS server is looking for the website on the internal system.
Are there any suggestions to remedy this problem without doing a domain
migration?

You have to use Split-DNS.

Since both Domain Names are spelled the same all the Split-DNS means is that
you have to enter Host Records ("A" Records) into you Zone for the resources
that are out on the Internet. when doing so use the Public IP# unless the
resource happens to be physically on your LAN with a Private IP#,...in that
case use a CNAME that points to the actual records for the Web Server on the
LAN to prevent trying to make a "U-Turn" through the firewall.

Example if the resource is physically out on the Internet:

Name Type Data
www Host (A) <proper IP#>

Example if the resource is physically on the LAN:

Name Type Data
www Alias (CNAME)
myLANservername.company.com

The line wrap screwed that one up.

Name Type Data
www Alias (CNAME) servername.company.com

I will add to Philip's post that to find the IP address of the web site, you
can use nslookup with any ISP DNS server.

Example:

nslookup - 205.151.222.250
> www.company.com

will give you the IP address of you web site. You can than add a Host record
with the address in your local DNS server.

This is a no-brainer. Just add a host record for www in their internal DNS
server's forward lookup zone for company.com - and assign it the public IP
used for the website.

Note that SBS questions are best posted in m.p.windows.server.sbs - although
this particular one isn't SBS specific, there are many things you have to do
differently in SBS. So it's good to at least crosspost there.

Thanks so much for the help!
