Yes it is integrated with ACS. The Hosts are not in ACS I have checked both by name and IP address.

This is your problem, then. In order for LMS to be able to manage devices, they must be clients of the same ACS to which LMS is integrated.

At this point, you have two choices. The first is to add the missing devices as clients to your ACS server, then logout and back into LMS. The other is to temporarily break ACS integration in LMS. Both will then allow you to delete the failing devices.

Thank You Thank You Thank You. After recieving your response to my question I added the hosts back into ACS, and then got busy with something else. I just got a chance to look at CWSI to see if I could find the hosts. Sure enough they were there and I was able to delete them. Thank You! You Rock!
