Endpoint 11 desktops joining Domain with AVG

We are bringing a computer lab that is using Symantec Endpoint 11 for its
anti-virus onto the domain. We are using AVG Network Edition 8 for clients on our domain.

The Symantec clients are running Vista, and the AVG clients are running XP Pro SP3.
Will this setup be problematic on the server?

Obviously, my Vista desktops will only have Endpoint.

I appreciate your help
