Is it possible to bar a PC\Laptop from a wireless system?

Is it possible to bar a PC\Laptop from a wireless system? We have a Cisco wireless network here and I want to block a particular machine from connecting through it.
This machine has the passkey but I don't want to have to change this because it means every other machine that connects will have to change their key.
I was hoping that I could somehow block it using its mac address.
I can't seem to find anything relevant in the online help, inless I'm phrasing the search wrong.

Does the wireless admin config page not have MAC Filtering?
If not, does your DHCP run from a Win2008 server? You could add the mac address to the mac filtering so that it won't get an IP address...

It looks like I might be able to do this through the wireless admin config. I was looking in the wrong place. I'd looked at MAC Filtering but that was for specific allowing MAC addresses. I've found the disable client function that looks like it will do the job.
DHCP runs from Server 2003.

can be sort of sont on 2003 just take the mac address and give it a silly ip reseration like 66.66.66.66

We use this

DHCP Server Callout DLL for MAC Address based filtering - Microsoft Windows DHCP Team Blog - Site Home - TechNet Blogs

Basically allows you to create a "blacklist" its not fool proof, is somebody is smart enough to assign themselves a valid static IP they can still get onto the network, but works well for phone's ect.

You need to move over to using a Radius server for your wireless authentication using AD security groups. I've got a single group wireless devices that I can remove machines from if I have to.
