When I delete an asset it reappears when i search again it comes back the asset has now been renamed and is appearing as its new name as well how do i get rid of the extra asset for good?

I am having difficulty scanning workgroup pcs. i have 16 in a workgroup i have added an administrator account with the same password to them all and mapped the credentials only 7 have scanned they are all set up in the same way firewall rules exactly...

Is there a report i can run which will give me a list of the internet history from the pc?

i am trying to get a report for all pcs but it isnt working it just either gives me all workgroup pcs or all domain i want a report of all pcs regardless of domain
