I just installed Symantec Endpoint Protection 12.1 on a standalone Dell Latitude D620 laptop running Windows XP SP3. I re-booted the computer and opened SEP. It appears the install was successful since it states my computer is protected and no problems are detected. However, "Scan for threats" is grayed out and none of the Symantec Security components (Antivirus and Antispyware, Network threat, and Proactive threat protection) are displayed. Any suggestions on what I need to do to fix this problem?
