用整那么复杂吗.
引用WMI,然后测试以下代码
Private Sub Form_Click()
Set colGroups = GetObject( "WinNT://. ")
colGroups.Filter = Array( "group ")
For Each objGroup In colGroups
Print "组名: " & objGroup.Name
For Each objUser In objGroup.Members
Print vbTab & "包含的用户: " & objUser.Name
Next
Next
End Sub
[解决办法]
.......
用户要是把WMI禁了 就不简单了
