Hi I user VPC on a WinXP Pro. The guest OS is Win2k. Sometimes the virtual mashine spontaneous reboot, like someone pushine a reset-button. I've get no error messages in this case A couple of times the host mashine also behaves like this, but only while the VPC is running. When the host has booted I get a message that the system has been restored form a crash. Any ideas to resolve these craches would be nice. /David
