This could be down to one of two things or both if your unlucky.

IT Solution

The first thing to make sure is that your firewall service is started, this must be started for the exchange install to be successful.

So click start run and enter services.msc make sure the service called Windows Firewall is started and set to automatic.

Then we also need to check the servers DNS settings. Make sure they are set correctley to point to your DNS server, this error can also point to incorrect DNS forwarding.Also if the server is a Domain Controller make sure that the forwarders are also set correctly.
