Lansweeper Error when Scanning Computer
In Lansweeper when scanning a computer it may report several WMI errors that say, “A security package specific error occurred. (Exception from HRESULT: 0x80070721)”
The Find solutions link takes you to a page that suggests it could be a firewall issue. While that could be the problem in my case it was that the time on the remote computer was 15 minutes behind. As soon as I corrected the time I was able to do a full rescan of the computer.
