Windows SBS 2003 DNS issue
Posted on 2011-10-21
We changed ISPs and the gateway address our network and now the SBS DC is struggling to route DNS requests to the correct provider.
We updated the Server DNS to forward to the new DNS for the new ISP. The update took effect immediately and outbound DNS requests were served just fine. This works fine all day. But every morning since we made the change, we have to re-boot the Windows Server in order to restore DNS to the computers on the LAN.
What could be happening overnight to knock out DNS on the server?
