1. Refer to the following Symantec Knowledge base article on how to pull the proper Sylink.xml file for the SEPM that you want that client to be managed by.
2. I created the following job to run from our Deployment servers and also via our Software Deployment Solution on our Notification Servers. If you don't currently use Altiris you can still modify this process to meet your needs.
cd C:\temp\sylinkdrop\sylinkdrop -silent -p YOURPASSWORD c:\temp\sylinkdrop\sylink.xml
cd "c:\program files\symantec antivirus"smc -updateconfig
***Note YOURPASSWORD is for the client password if you have one required to stop and start the service on your clients.***
@ Doctortt,copy the default sylink.xml file from the SEP CD-1, present in the SEP folder, and replace it in the SEP installation folder. This will change a managed client to an unmanaged one.

This issue is addressed in the Symantec KB
Keep in mind, though, that "if you change the client to unmanaged without ensuring that you can change settings on the client [e.g. lockdown policy], you may need to uninstall and then reinstall the client if you need to change settings in the future."
