Convert Unmanaged client to managed one

Hi All,

I’m testing the a Dell computer with 64-bit Win7 OS and start to do an image for it. The Symantec installed on this PC is 12.1.4_Win64-bit-Client. I’ve been struggling to figure out a way to have this client PC to communicate with Symantec server.  For 12.1.3_Win32-bit_client version, we use Symantec replacer to do the sylink and got success. However, it doesn't work with 12.1.4 version. Is there anyone who can help me out? Since i don't have the privledge to do anything on server side, is there any way i can sylink it on client's side to convert it to a managed client?
