You may be able to get the whole DNS string 5 like this:


We don't have full fledged DNS 4 names where I work, but it does give me 3 a three level faux domain name instead of 2 just the hostname.

I used this very similar method:

var serverName = System.Environment.MachineName; //host name sans domain
var fqhn = System.Net.Dns.GetHostEntry(serverName).HostName; //fully qualified hostname

If the above doesn't work, you can also 1 try retrieving it from the environment:

var dnsName = new StringBuilder();
