Get the MACHINE domain, not the user domain.

[SiPearson]

Hi,

I'm writing an app that needs to get the domain the machine running it
belongs to. I know that you can do a Environment.UserDomainName, but
this returns the domain the user has logged onto.

What I have is a machine that sits on a resource domain called ***Res,
and a trusted domain the user logs onto the machine called Global.
The user always logs onto Global, but the machine could be on BobRes,
BillRes or BrianRes.

I'd be grateful if someone could help me found out which domain the
machine is on.

Many thanks

Simon

You have some options, in order of preference:

- Use the System.Management namespace classes.
- Use the System.DirectoryServices and the NT4 ADSI provider interface
- Use PInvoke

Here's a sample using the first:

....
ManagementObject cs;
using(cs = new ManagementObject
("Win32_ComputerSystem.Name='yourSystemName'" ))
{
cs.Get();
Console.WriteLine("{0}",cs["domain"].ToString());
}
}
...

Hi simon

Thank you for posting in the community!

Based on my understanding, you want to get the domain's name which your
machine belongs to, but not the domain your user logon.

=================================================
Just as Willy suggested, you can use System.Management classes to work for
you.

Actually, System.Management classes use WMI to get the system information.

I have tested Willy's sample, it works well.
