RasDial命令 实现个ADSL偶尔拨号失败问题请教，进入有vb代码贴出，急
第一次调用拨号基本上都能拨上号，ip也能换，为什么拨多了2次就很容易失败
我想实现个抓取工具，结果抓取多了，就想重新拨号换ip
结果呢，会出现拨不上号的现象，有时拨上了ip也没换，不知道是什么原因？
请大家出出主意，谢谢,关键代码帖个大家看看。

Public Function AddConnection(strNewEntryName As String, strNewPhoneNumber As String, strNewCallbackNumber As String, strNewUsername As String, strNewPassword As String, strNewDomain As String) As Integer
Dim lngRetCode As Long
Dim lngRetLstrcpy As Long
Dim lngRetHangUp As Long
Dim lprasdialparams As RASDIALPARAMS95

------解决方案--------------------
用过这种，但没遇到你说的情况。与你的ADSL设备质量有关？
