Dumb Terminal KVM type device?

view story

http://serverfault.com – I am looking for a device that will help me in my situation; I am looking to replace workstations that I have on LAN, with a device. This device would have a monitor, keyboard and mouse connected to it. Perhaps a KVM over IP type device. This device would connect to a Hyper-V virtual running Windows 7 on the local Windows 2008 R2 server. Does such a device exist? (HowTos)
