mitchelt,
I don't know if there is a better way -- I'm sure someone will post it if there is -- but one "if all else fails" method suggested by one of the Norton Staff was to cancel the activation on one entry in Norton Management and then check the computers in turn to see which one it is and then give it a more user friendly name. Or even to cancel all three and then as you reactivate you can rename.
But that really only works if you have local access to all of them.
I hope someone comes up with something more direct.
I don't think it has happened to me since when I built my PCs I changed the label on the hard drive partition that contained Windows to a user friendly one that identified what version of Windows was in it and which physical and logical drive it was on so that for example my current OS drive is labeled, believe it or not
OS3SATA2P1-WIN7HoPr-32-EEE
OS3 means it is on the computer I call Ollie 3
SATA2 means SATA drive 2 since I have 2 physical hard drives in it
P1 means the first partition
The it's pretty obvioous: Windows 7 Home Premium 32 bit
EEE reminds me that the drive letter when Windows was installed was Drive E: (It's a multiboot computer with 4 different versions of Windows on it! And despite popular belief Windows does not always have to be running on Drive C:
The bit about the drive letter can be very useful when drive letters do get temporarily changed and you are looking to find a file!
Obviously you can do something simpler but having done this I found that Norton Management picked up my label and used it.
You can do this labeling using Drive Management or simpler for a single drive/partition by opening Windows Explorer (the FIle Manager) by pressing the WINKEY and E keys at the same time. And you can do it safely as far as I know on a purchased computer after you get it.
Right mouse click on the partition that contains the operating system (C: unless you have something odd like mine) and select Properties. You will see on the General TAB a box with something in it which in my case is the label I showed above. You can highlight what's in the box and change it to what you want to use like Mitchel Asus notebook or whatever suits your situation and then OK your way out.
What I don't know is what happens if you do this after you have a different label showing in Norton Management .... You might try and see if it refreshes but I doubt it.
I hope that helps rather than confuses.
