Designate Scan Point and Run Nmap Scan Failing

Usage and Config
1

Bigfix version 10.0.7.52. I ran ran fixlet 260 Designate Nmap Scan Point on a system on an SD-Wan subnet. It failed.

Failed continue if {exists key "HKLM\Software\Npcap" of x32 registry and       version of file "Uninstall.exe" of folder "c:\program files\Npcap" >= "1.79.79.117"}

However, the scan point shows as relevant as a scan point for fixlet 226 Run Nmap Scan. But, then the scan fails at the following point, and I do not get any scan data.

Failed regset "   [HKEY_LOCAL_MACHINE\SOFTWARE\BigFix\EnterpriseClient\BESScanner-NMAP]" "NumberOfScansRun"="{value "NumberOfScansRun" of key "HKEY_LOCAL_MACHINE\SOFTWARE\BigFix\EnterpriseClient\BESScanner-NMAP" of registry as integer + 1}"

When I run these fixlets on a regular LAN subnet, they work like they are supposed to.

The problem in my case was that we had Cisco ThousandEyes installed which also uses Npcap. I did not dig into the exact reason the scan failed, but when ThousandEyes was removed, the Bigfix Designate Scan Point and Run Nmap Scan ran as expected.

All those pesky things causing interference! :grinning:

I was going to remove ThousandEyes anyway, but what if I couldn’t remove it? What would the solution be then?

At a guess, probably either a manual update of NPCap to the version we expect, or update of the task to force upgrading the NPcap version – which of course might cause a problem on ThousandEyes, which one would have to ask them to correct if it does introduce a problem.
