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,

Answer 1

System.DirectoryServices.ActiveDirectory.Domain.GetComputerDomain() wraps DsGetDcName which will search the network for a domain controller even if the machine is not part of a domain. (see remarks)

As alternative to NetGetJoinInformation you could use GetComputerNameEx with the COMPUTER_NAME_FORMAT.ComputerNameDnsDomain flag to get the full DNS domain name.

(If not part of a domain, it still returns true, but the resulting string will be empty.)
