External Domain problems with SBS Premium

Just something to keep in mind if you're using SBS Premium. Most clients want to see their web page when they type in companyname.com into their web browser. Depending on your Active Directory setup you may not get what the outside world sees because of the internal DNS resolution.

Remember to create another forward-lookup zone in the DNS admin and then put in a host (A) record of www with the IP address of the external web page.

One thing that we recently ran into is what happens when that external IP changes? Well usually just a simple DNS change will make it right. However if you don't see it appear immediately on the server don't be alarmed. With SBS 2003 Premium edition running ISA Server remember that we are using a Proxy server. It'll take some time to update that Proxy server by default so change the IP and then come back tomorrow if you like. You'll see the updated external web page and so should your workstations.
