Scan not finding new systems

[sysadmin]

I run scans of my subnets periodically as we are always adding new servers. The scans do not find any new servers. If I scan the new server IP individually the scan completes fine. Why does the scan of the entire subnet, xx.xx.xx.xxx/24, not find any new devices?

Please let me know if I am missing something.

 

Thank you

Have you tried to enable (or disable, if it's enabled) the Nmap engine? It can be done either on the Scanner tab or in the "Options - Scanner" window. This influences the way the network discovery is made.

Do these servers reply to pings normally?

[sysadmin]

yes I have enabled/disabled nmap engine. Yes the server replies to pings normally.

Any update?
