I recently changed the ip address of router/server on a 2008 SBS server environment.  After the change the external website can not be viewed from any system on the local network.

There must be some dns record stored somewhere on the local server that is causing this issue...

Please help!

Hello,

On the local server, go to the command prompt and type ipconfig /flushdns

This will clear the DNS cache.  I think you can also look at the DNS settings in 2008 SBS Administrative Tools and make sure the lookup zones match the new IP address.

Did you look in DNS on the server and the forward lookup zone of your domain.com should have an A record pointing to the external website address.

There are two records under the Forward Lookup Zones referencing steelecpas.com

  Start of Authority (SOA) and Name Server (NS)

Which should be modified, and where does the external reference go?

You need to right click the steelcaps.com click  add "A" record, name it "www" and put your external IP adress in the address bar

If you run the "fix my network" wizard in the SBS console under Network | connectivity, it should update DNS for you
