VPN still worked this afternoon. But tonight it shows error 868. I use a software which helps me to disable some unessary services. But I didn't disable any new service today. Today I installed acrobat and photoshop cs5

I would restore a restore point before the problem occurred. -------- Regards, Hank Arnold Microsoft MVP Windows Server - Directory Services http://it.toolbox.com/blogs/personal-pc-assistant/ On 12/12/2010 8:00 AM, EsionLin wrote: VPN still worked this afternoon.

Just a minute ago, I tried to connect vpn and now it works! Why? I did nothing!
