Can't see my device name in Norton Management

Hi,

 

I had three computers; I installed Norton Internet Security on all three; so far so good.

 

But the oldest computer is now dead and gone; I went and bought a brand new HP desktop. Great.

 

I am trying to "remove" the Norton service on the old machine that is now gone. But in the "Norton Management" dialog box, it shows the column with the 3 device names, but only one name is actually identified or "listed". The other two are simply shown as a hyphen. There should be a real computer name in at least one of those; maybe even both. I even know what the name is, but I do not know which of the two remaining devices it is, I need to sedn it to trash, btu I on't want to inadvertantly send the WRONG one to trash.

 

Why can't I see the device name(s)for the other system(s)?

 

I can't [safely] update my home computer setup w/o knowing whuch system is dead and gone yet.

 

Thanks fro any help at all.

 

Michael
