Question

How can I check from C# if a local user account (namely the local Administrator account) is active?

What I actually want is a C# replacement for the “Account Active” = “Yes” (or “No”) output from the “net user Administrator” command.

I’m afraid this question looks like a duplicate to this one, but I don’t know what to pass in for the parameter for the root DirectoryEntry object. Tried different things like “ldap://” + Environment.MachineName, “ldap://127.0.0.1”, “WinNT://” + Environment.MachineName, but none of them worked. I get an exception thrown by the searcher.FindAll() call in all three cases.

class Program
{
    static void Main(string[] args)
    {

        // Create the context for the principal object. 
        PrincipalContext ctx = new PrincipalContext(ContextType.Machine);

        UserPrincipal u = UserPrincipal.FindByIdentity(ctx, IdentityType.SamAccountName, "Administrator");
        Console.WriteLine(String.Format("Administrator is enable: {0}", u.Enabled));

    }
}
