I have a problem with the VPN connection.
My system is Windows 7 SP1 Ultimate x64.(Installed 1 month ago) I created a VPN connection to my company network. The connection is automatic, and choose the PPTP protocol to connect. After I connected the network, I can browse the network drives without problem. If I like copy 3Mb or greater file to my computer or to the server, the VPN connection was freeze my notebook before the file copy is starting. Than the notebook freezed, I must remove the battery to restart it.
In the log I cann't see any abnormal, just the Kernel-Power event shown.
