Hi there, I'm the Community Manager over at the Spiceworks forums. There is a helpful article on how to resolve any problems with finding and identifying devices during scans here:
Devices Are Not Showing Up In Spiceworks - Spiceworks Community
You can also ask questions in your support forum:
Spiceworks Support - Spiceworks Community
We have community members and support staff on hand who can help out with any problems.
Thanks,
Nic
