DNS

I recently deleted the “.” zone out of the forward lookup zones and took the remaining zone and put the forwarders in for the ISP. I have the clients getting the local DNS and the 2 ISP servers for their DNS servers (the local being the primary). I have the following issue: our website (which is the same name as the remaining forward lookup zone) doesn’t resolve by name internally (it will by IP). It resolves fine externally. I wonder how I fix this???
