add it as an idea. However the care needs to be taken as there is KB article available.

Check this link. There is tool available ( refer the link below)

How to repair duplicate IDs on cloned Symantec Endpoint Protection 12.1 clients

http://www.symantec.com/docs/TECH163349

My biggest question with that though is that it says to put all the affected clients into a group but if there are duplicate ID's and the clients keeps re-appearing and disappearing how can you get them all in to the group?

when you create a image and have SEP it will be registering to the group ( the package has).

That I know. But let's say I create this image and forget to remove the hardware ID and deploy it to 3 clients for example, I know have 3 duplicate hardware ID's. According to that symantec tool though, it says to put the affected clients, in this case those 3, into a group and deploy the tool on the group. But how can you get them all in to 1 group if only 1 can show up in the console at a time due to the duplicate hardware ID's?

Do you have the smc password set? if not jump to point no 4).

So I followed the documentation on correcting the duplicate ID's, deployed the setup.exe to the clients through the Management Console and still none have showed up. Any thoughts on this?

can you enable the sylink log on the client that is not reporting and post it here?

What's the file name for it? You're not referring to the sylink.xml are you?
