Endpoint Protection

I read this great artical on how to repair duplicate IDs on cloned SEP 12 machines, along with the RepairClonedImage tool you rename setup.exe,

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

But what about SEP 11 clients?

When we used the RepairClonedImage tool (renamed setup.exe) on a SEP 11 client we get error

Where is the RepairCloneImage tool we can use for SEP 11 clients?

NOTE: It is not feasible to upgrade these production servers to SEP 12 at this time.

This doesn't exist for 11.x. It needs to be done manually

1.  Stop SMC on both of the affected client computers by clicking Start> Run, type smc -stop then click OK.
2.  On the SEPM console, delete the client entry that the two computers have been sharing. This will prevent the client duplication that would otherwise occur due to the following steps.
3.  On each of the affected computers, go to registry location: 
     HKLM\Software\Symantec\Symantec Endpoint Protection\SMC\Sylink\Sylink
4.  Clear the value for "Hardware ID." (make it blank)
5.  Disable Tamper Protection if you are unable to edit the value.
6.  On each of the affected computers, navigate to the following directory location:
     SEP 11 Location:   
        C:\Program Files\Common Files\Symantec Shared\HWID
     SEP 12.1 Location:  
        Windows XP/2003: C:\Documents and Settings\All Users\Application Data\Symantec\Persisted Data 
        Windows Vista/7/2008: C:\Program Data\Symantec\Symantec Endpoint Protection\Persisted Data
7.  Find file "sephwid.xml". Rename it to "sephwid.xml.bak".
8.  Start SMC on each computer by clicking Start> Run, type smc -start then click OK.
9.  Check the SEPM console for the new SEP client 
     When the clients check in they should have unique hardware IDs.

its not for SEP 11, you need to do that manually.
