delete learning device in CiscoWorks

I am having an issue with Ciscoworks hanging in the learning state on a device on my network. My "About" section displays this:
LMS2.6            01 Dec 2006
QPM4.0            16 May 2008

I put the device in there using the FQDN and the IP address. After doing a nslookup on the FQDN, I noticed that the IP address was wrong. So I populated the 6 DNS servers on the network with the correct forward and reverse lookup zones and instructed the DFM to rediscover the device. I gave it a day. It found the device, but called it questioned (I forget why).

So, I thought that somehow, in my error with not making sure thatthe DNS records were correct, it had somehow tainted this addition of the decvice.

So, I tried on Friday to rediscover the device again. I came back on Monday morning to see that it hadn't progressed at all (10%) and that it has the wrong IP address (old one) smack on the top of the box (while viewing it through the rediscover/delete page).

I cannot delete this device. It does not show up in the device selector becuase it hasn't been learned yet and when I go to the Rediscover/Delete page, the option to delete it is greyed out. When I deleted it previously, I used the Add Device page because it would not show up in the device selector due to it being questioned.

Help would be good, but I also need to understand my error.

Thanks!!!!
