SBS 2003 DNS configuration to access subdomain

I look after a small SBS network that is configured with its external domain name abc.com (before I knew any better).
The website http://www.abc.com is hosted externally and I have setup a host record  to access this domain from the local PC's.
No problem so far.
The website now has a subdomain http://123.abc.com which is accessable from any PC outside the network but not from the internal PC's.
Have tried creating a sub domain, but the local PC's get a page cannot be found when trying to navigate to it.
Any suggestions would be appriciated.

Why not just add an additional HOST record to the DNS Forward Lookup Zone for 123.abc.com?

Jeff is right.  Just go into the DNS management on your SBS server and create a "Host (A)" record.
1) Go to your domain name under the Forward Lookup Zone
2) Choose to create a "New Host (A)" record
3) Under name enter "www" and then enter the public IP address of the webserver that is hosting the site.
Users inside the network will have to enter the WWW in order to view the site.

Well, that's almost what I said.  You will create a new Host record that points "123" to the public IP address of the web server.

I'd assume that there is already a record for "www".

Thanks for the input chaps.
I tried adding a host record for the subdomain but it does not point to the correct location on the website (just get the page 404 error)
Jeff, as surmised, I had already added the record for www  which points to the ip of the website. This is how the local users access the site. However creating a similar  A record for the 123 subdomain does not appear to work in the same way.
My rational is if it works in the big www I should be able to setup DNS in the local network to get it to work. Do either of you know what i could do to interogate the web name servers to get enough info to solve this problem. Thanks.

On the web server how did you create the subdomain?  What kind of web server is it?  I assumed that because requests from outside your LAN to 123.domain.com went to the proper place that you had things configured correctly on the server end.

If it's a Windows Server running IIS, you would be using Host Headers to send a request for 123.domain.com to the proper directory.  If it's an Apache server you would use Virtual Hosts in the httpd.conf file to designate the directory.

So, assuming that this is the case, then the 404 error is generating an entry in your Web Server's error log.  Look at that line and see what the actual request was that was sent from your LAN.  If you need help interpreting it, past just those few lines here.
