Activex component?

[Dumb Luck]

I am trying to get a list of groups from my NT domain using vb. This
is my code.

colGroups = GetObject("WinN T://myDomain/,Groupcollectio n")

For Each Group In colGroups
Label1.Text = Label1.Text & " " & Group.Name
Next

When I run it, it says cannot create activex component. But if I do
this it works fine.

colGroups = GetObject("WinN T://myDomain/Domain Admins,group")

Label1.Text = Label1.Text & " " & Group.Name

I don't understand what is going on. Any ideas would be a great help.
