Machine's domain name in .NET?

Question

There gotta be an easy way to do this, I can't believe there's none. I have scanned through net and found, like, 20 different methods to find in which domain current user is, but none to get domain (or workgroup) of current machine.

In unmanaged c++ this is retrieved by:

WKSTA_INFO_100 *buf; NetWkstaGetInfo(NULL, 100, (LPBYTE*)buf); domain_name = pBuf->wki100_langroup; 

can someone help me, if there's a way to get same info in managed C# natively?

EDIT1: Folks, please read the question. I am NOT looking for user domain name.

Answer 1

To get the current domain of the system on which your progam is running you can use System.DirectoryServices.ActiveDirectory.Domain.

Domain domain = Domain.GetComputerDomain(); Console.WriteLine( domain.Name ); 

Answer 2

I work on a project where users could be anywhere; non-domain users on a domain machine, users on a non-domain machine, not directly connected to the domain on a third party network, etc. so depending on AD is already a non-starter.

System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName is far more reliable under all of these conditions.
