Windows – Share desktop monitor/keyboard/mouse with laptop

You could set up a KVM between your keyboard, mouse, and monitor and the docking station and the other laptop. Basically, for purposes of setting up the KVM switch, you would pretend that the docking station is the computer itself (ignore that it's actually a dock). This would allow you to switch the external monitor, keyboard, and mouse between the two devices.

Note that you might want to look in to Synergy, this would allow you to control both computers very easily, but you wouldn't be able to switch the monitor between the two (Synergy just handles control, not video).

It turns out my usb.inf-file has disappeared from c:\windows\inf. I had to copy one from an other machine. That did the trick. Now everything works again.
