How do I enable an excluded client on Cisco 4400 Wireless LAN Controller

I am adding a Cisco WET200 bridge to an existing wireless network.  The network is managed by a Cisco 4400 controller and I have enabled bridging.  I had this working, in my office, but when I moved the WET200 out to the plant it changed AP's and now the controller has it tagged as 'excluded'.  Here's the message:

Reason:Attempted to use IP Address assigned to another device. ReasonCode: 3

It's not a IP conflict, so how do I get the controller to move past this?

ooo 4404 - a problem child.

Are you using the WCS? Run a search by the device's mac address, and the proposed IP address. Ensure there is no conflicts.

Then you can always Check out > Configure > Controllers > Security > Wireless Protection policies & manually disabled clients.

Before jumping, I would also suggest trying a different IP address on the bridge (you never know)

I did some extensive testing with some wireless bridges on a 4404 network, and guess what - none worked. I tried everything from $20 ebay bridges through to $700 3comm/motorolla gear and all proved to not work. After speaking with Cisco TAC, I spend about 3 days on the phone and slowly increasing rungs of the support ladder, untill their final response was, and I quote " Sorry but, the 4404 obviously wasn't designed to work with wireless bridges" case closed. ... Strangely enough, I did hear rumours that the latest firmware supports them?

I got it working.  I had to disable the "IP Theft or IP Reuse" option in the Client Exclusion Policies.  I'm not too happy about having to essentially reduce my security level to get two Cisco products to work with each other, but it is what it is.
