Need to add domain user to local group

T

Terry Olsen

I'm trying to add a domain user to a local group using the code below:

Dim LCL As New DirectoryEntry("WinNT://" + Environment.MachineName +
",computer")
Dim DOM As New DirectoryEntry("WinNT://us.ups.com")

Dim DOMUSR As DirectoryEntry = DOM.Children.Find("USERID", "user")

Dim LCLGRP As DirectoryEntry = LCL.Children.Find("LOCAL_GROUP", "group")

'LCLGRP.Invoke("Add", New Object() {DOMUSR.Path.ToString})
'LCLGRP.Children.Add(DOMUSR.Path.ToString, "user")
'LCLGRP.CommitChanges()

Trying the "Invoke" line throws "Exception Thrown by the target of an
Invocation."

I would sure appreciate some insight. Thanks!
Trying the "Children.Add" line throws "The Active Directory object
located at the path "WINNT://Domain/Computer/LOCAL_GROUP is not a
container."

Nevermind. My bad. I wasn't checking the InnerException. That revealed
that "the specified user is already assigned to the group".
It works fine (using the .Invoke line).
