DNS.GetHostName (or similar) returns the incorrect DNS name of the localcomputer - if the hostname is different from the DNS name.

​

For example:

Current computername in Widows - WIN-12345

Updated computername in DNS - ABC-XYZ.mydomain.com

This is the only DNS entry for the device.

​

I want to query DNS to return the latter of the two above, running ON the device in question (192.168.1.1):

Console.Writeline(DNS.GetHostName(IPAddress.Parse("192.168.1.1")));

WIN-12345

​

If I query that same computer from a remote device with the code, I am returned the correct DNS name:

ABC-XYZ.mydomain.com

​

So, when run locally, not only does it not return the FQDN, but it also returns the incorrect name that DNS holds.

I have had to revert a process running NSLOOKUP to return the correct information.

​

​

Any ideas how to query DNS correctly in this situation using native code?
