Norton is blocking DLNA server (WMP)

My NIS is blocking Windows Media Player and I'm unable to play files on my TV (dlna enabled). It's OK if I turn off the Inteligent firewall.

What is funny, is that I have 2 laptops in my home network running XP with NIS 2012, with the same settings and one works fine, the other doesn't.

Why?
