Hi people,

Can anyone please let us know in how to disable the SEP client temporarily ?

I have tried the smc -stop command from Start | Run but somehow my laptop is not ping-able performing a direct connection peer to peer with a patch cable.

smc -disable –ntp

To enable client firewall service

smc -enable -ntp

If the SEP client UI is password protected:

smc -disable -ntp -p <password>

I hope it's been informative.

Thank you for posting in Symantec community.

I would be glad to answer your query.

There is only one command to disable SEP client, you can execute the command multiple times if it's not working.

Start --> Run --> smc -stop 

If possible restart the machine and execute the 'smc -stop' command

Refer this article if want to know more about dos commands

No, you need to stop the SNAC services from services.msc

above cmd will disable the Network threat protection of SEP. SNAC is a different module.
