突破Windows 自带VPN 拨号次数99次的限制

最后2008总是断线，内置的99次根本不够用，所以要想办法增加一些

首先想到的是，播号联接会写注册表，就监视了一阵子，没发现什么情况。

根据键值:查到播号联接会启动一个服务：

Network Connections Service

Service Name	Netman	Process Name	svchost.exe -k netsvcs
Default Settings	XP Home: Manual	XP Pro: Manual
Microsoft Service Description	Manages objects in the Network and Dial-Up Connections folder, in which you can view both local area network and remote connections.
Dependencies	Remote Procedure Call (RPC)
Real World Description	Basically, it controls the network and your ability to connect to the internet via Dial-Up.
Is this service needed?	Yes	Recommended Setting:	Automatic

于是从服务中，查到该服务为手动启动。开始监视svchost程序的一举一动，发现其会读写

C:/Documents and Settings/XXX/Application Data/Microsoft/Network/Connections/Pbk/rasphone.pbk

或者C:\ProgramData\Microsoft\Network\Connections\Pbk下面的rasphone.pbk

这个文件，打开一看RedialAttempts=99，即为重试次数。修改成32767, 完成任务．
