Endpoint Protection

I have a number of computers on my network running Norton Internet Security 2010, and some running Symantec Endpoint Protection 11.0. I would like to add the computers running Symantec Endpoint to the Network Map for Remote Monitoring, similarly to how I add the other computers running Internet Security 2010 using a passphrase. Is this possible at all?

its not possible to link SEP with other version of symantec security product
SEP can only talk to SEP

 SEP is enterprise and Norton is for home...
It is something like  linksys router and cisco router...both of them are one company do similar job but cannot be compared or configured together.

I suspected as much. Thanks for the replies!
