I have T530 and windows 8 x64 on it, I have noticed that after some time of using it I was unable to connect to PPTP VPN or my SSL VPN.
The error stated during the connection to the PPTP VPN (windows client) was 720 error.
I restored my windows via recovery to the point one week before and VPN started to work again. I was trying to isolate the problem after which installing I became having such problem. What I have noticed is that there are two lenovo updates that are casing this problem (I'm not excatly sure which one it is, becouse after installing them I had to restart computer about 2 or 3 times to reproduce the problem). After the problem occurs it's constant and I could not find a solution this.
The updates I am talking about are:
- Intel PRO/1000 LAN Adapter Software for Windows 8 64-bit (ver 126.96.36.199 - no previous ver installed)
- Lenovo Settings Dependency Package - 8 [32,64] (ver 188.8.131.52 - no previous ver installed)
I've notcied that there was a similar problems on older versions of windows - does anybody know if those instrucions are valid for win8?

I have seen those posts. Howevver in my opinion there is something wrong with those updates i Have mentioned - they are responsible for this problem....

thank you, I thought that my Cisco client install, or Kaspersky antivirus were responsible for this. And uninstallation helped not.
But for a very long time helped me to use previous restore point. And I am sure that there was no installation betwen VPN wotking-not working points. There was only a question of time.

I gave up and reinstalled windows. Installed all lenovo drivers by hand and let windows updater do its job. No problems so far.
