HI,

are you able to telnet 8014 ?

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.
