I got a new lap top back in Feb, my old one had home on it.  With my old computer I could share pictures with my wifes computer on the home network, the only network I get on.
 
My new computer has xp pro on it and we can not figure out how to share my pictures, I can see her computer and her shared folders but she can not even see me on the network.  Is there a firewall setting keeping me hidden?

When I look under Windows Security Center it says some of my setting are controlled by group settings....

We are running Windows One Care....
