@x23piracy You can look in the access log and hopefully see the host that applied this mac address.

172.19.101.150 belongs to IT4314 hrhr

So what we know, so far, is it appears IT4314 IS registering these pending macs?
-
@Tom-Elliott after chatting with tom we decided to remove the fog client from it4314, i also removed all the pending macs again. Now lets wait what happens.

@Tom-Elliott @george1421 @Wayne-Workman It looks like the pending macs have stopped accouring since i uninstalled the fog client from the machine it4314, can someone identify something crude in installed software, ipconfig and or network nics? My post before with the Screenshots.
-
@x23piracy This is interesting. Did you only uninstall the fog client, or did you delete the host in fog too? Also, we must remember you put those MACs in the mac filter list as well. All those things are in play still. We need to eliminate variables.
-
@x23piracy Windows 10 has this feature to “randomize” mac’s to help prevent hijacking of your ip’s. Maybe this is enabled on this machine?
-
@Tom-Elliott Why on earth would they do such a thing.
-
@Wayne-Workman “In the name of security”
-
@Tom-Elliott no since this notebook has been deployed with our image this can’t be enabled, the only option could be the user itself. I’ve never heared about this where can this be enabled/disabled?
-
@Tom-Elliott @Wayne-Workman the system is currently not in house so i cannot proof this.
I found the option: https://superuser.com/questions/1212736/random-hardware-addresses-in-windows-10-creators-update/1212749I will check this if the system is reachable.
Regards X23

FYI, i don’t know if the random mac stuff is the issue, i could not reach the notebook today user was already gone for the weekend, i will report next week.

@Tom-Elliott @Wayne-Workman @george1421 Hey dudes this random mac option for wlan was really enabled, since i didn’t knew it was existing i have to disable this by gpo, this user enabled it on it’s own, he thougth it would be a good idea, no it’s not for FOG Thank you Tom for giving the solving idea
Where is the option to mark as solved? Can’t find it.

@x23piracy Mark as solved is only available for moderators and developers and such, to prevent people from solving too early and what not.
