please help me urgently as system is on priority.

Hi,

Please provide sylink logs

Are the client showing green dot ?

It's managed client ?

Whst OS version are you using ?

If incase these machines are Windows 7 machines, I would recommend you to:

a. Disable the Windows Firewall or create exceptions for the ports on these machines to communicate to the SEPM http://www.symantec.com/docs/TECH163787

b. Disable the UAC (User Account Control) and restart the machine.

c. If that does not work, please provide us with sylink.log from one of those machine.

uninstall / reinstall the live update
