解決windows 7 下VPN串連時的651錯誤

引子   

     現在總有些網站打不開，自然也包括了一批不錯的技術網站和資訊網站，而我們高技術的入門準則正好應該加上一條要學會跨越一些障礙。VPN成了不少IT同仁的一把利器，以前會用一些線上代理湊合湊合，或者使用某些特殊的瀏覽器外殼，VPN也用過不少（有關VPN的資訊，推薦http://www.free8.com/tag/mianfeivpndaili,有相當不錯的資源）。

    廢話少說，直接切入正題。今天嘗試在windows 7作業系統中建立一個VPN，可是很倒黴，總是碰到這樣一個錯誤：一個視窗彈出來“all devices connected”，還沒來得及點擊“確定”，壞訊息來了“"Error 651: The modem (or other connecting device) has reported an error".

    解決方案找到了——卸掉你機器上的VPC 2007 SP1，如果有的話。

問題描述

I am not sure exactly when this started happening but as of 6/5 it was still working. 
When I try to connect to my company's VPN (via PPTP) I get an Error 651.  There is a dialog window that opens that says "all devices connected" ... not sure what is going on.
I disabled all firewalls and even uninstalled Kaspersky.  Still, same error.
I re-created the VPN network connection, still same error.
I uninstalled any of my recently installed programs (iTunes upgrade, etc.).  Same issue.
I performed a System Restore to 6/5 and I am still getting the same issue.
I have this happening on my home desktop as well as my work laptop from two different locations (will try more when I get a chance) through both wired and wireless connections.  As far as I know (and have been told) nothing has changed on my corporate LAN.
The only things I see online for this error are related to PPPoE and firewalls ... not sure if PPPoE has anything to do with it at this point.
Any other thoughts on what I can try?
Info:
Windows 7 RC, all latest critical and even some optional updates installed
Laptop: Dell D830, 64bit, 4 GB RAM, 80 GB HDD
Desktop: Pentium 4, 2 GB RAM, 120 GB  HDD

Thanks,
Jason

解決方案

I have the same problem after VirtualBox installation.
Uninstall VirtualBox solve the problem for me.
Do you have VirtualBox or other Virtualization software ?
