如何扫描出局域网内的所有机器？

查找局域网的所有用户（别人的东西,不是我自己写出来的）
    方法一：
Private Function PutUserToList(strDomain, strUserName, StrPasswd, lstUser As ListBox) As Boolean
On Error GoTo err1:
Dim o As Object
Dim cont As Object
Dim usr As Object
lstUser.Clear
If (strUserName <> "") Then
    Set o = GetObject("WinNT:")
    Set cont = o.OpenDSObject("WinNT://" & strDomain, strUserName, StrPasswd, 1)
Else
    Set cont = GetObject("WinNT://" & strDomain)
End If
cont.Filter = Array("user")
For Each usr In cont
  lstUser.AddItem usr.Name
NextPutUserToList = True
Exit Function
err1:
PutUserToList = FalseEnd Function
对了。只有win 2000支持adsi，NT 4.0要打一个包。如果还不行。就可能是网络有问题或是相应的服务没有启动

   谁有完整的获得一个局域网中所有机器信息的源代码？

xiaowh(大河向东流):方法二你试过吗？在我的机器上怎么不行？”找不到NetServerEnum在Dll的入口点“，请关注，谢谢！
请问上述代码　在WIN98。WIN2000运行都通过吗？
