SCCM Does not Discover Computers non joined to the domain

Network Discovery isn't used very often.
How did you configure it?

https://docs.microsoft.com/en-us/sccm/core/servers/deploy/configure/configure-discovery-methods#bkmk_proc-config

the non-domain joined computer is in the same subnet as the one displayed on the screenshot

its IP address 192.168.254.130 and the Firewall is disabled and can ping from the computer to SCCM and Back

C:\Users\user>ping 192.168.254.129

Do you see the start and stop status message for network discovery ?

Netdisc.log in SCCM \Logs directory is worth a look

in logs Directory , there is no Netdisc.log file

I mean in this location :


C:\Program Files\Microsoft Configuration Manager\Logs

Hm I don't know what's causing this. Here's the list of log files

https://docs.microsoft.com/en-us/sccm/core/plan-design/hierarchy/log-files#BKMK_MPLog


The log file is on the site server:

netdisc.log    Records Network Discovery actions.  Site server

I have attached the netdisc.log
netdisc.log

the address of the computer non-joined to the Domain is : 192.168.254.130

not sure why. Though I can ping the computer from SCCM server:

C:\>ping -a 192.168.254.130

I 've never used Network Discovery. So I only thought its using ping to scan a network, but it's not.
What I saw in the document means it's using DHCP or SNMP to query for clients. If both not available you can enable network browsing.

If both not available you can enable network browsing.

how do you do that?

Hm, sorry.. I don't remember ... but I found this:

I will get to SCCM LAB Later.

Thank you
