vScope searches ranges using ping- and port scan methods. vScope’s normal behavior is to first try ping. If ping does not return any response, vScope continues to test a few commonly used ports. To disable vScope’s port scan fallback, do the following:

• Stop vScope Server service
• Open the file C:vScopeDataconfigurationconfig.ini (This file may be on another drive)
• If there is no such file, create it.
• Add this line to the file: discovery.scanprobe.rawping.portscan_fallback=false
• Restart the vScope Server service
