Hello I have about 150 pcs that are being blocked from our NAC because of the SEP firewall.  How do I turn off the firewall for these 150 pcs?

Withdraw the firewall policy

You should just be able to create an allow rule though

Hi,

You can do it from SEPM console as well.

Right click on computer and select disable NTP. See if it makes any difference?

If not helped, assign new custom package by removing NTP package. Reboot would required to remove the NTP feature completely.

Just uncheck the firewall policy or you can remove it...

You can move that client in a single particular where no other client available then withdrawl the firewall policy there.

If it still create problem then as Chetan Sir assign the custom package where no ntp component avaiable.
