Can't connect to Mac on my network

[angemon89]

I am having trouble connecting to my brother's Mac Mini from my iMac. We are both connected through a wired connection running to my Airport Extreme Base Station (Fast Ethernet).

I can see his Mac Mini in the leopard finder sidebar but I can not connect to him. It just hangs and looks like its trying to connect. Any idea what could be wrong? When I click on the "Connect As" or "Share Screen" buttons, nothing happens.

EDIT: He can mount my computer but I can't his.

Did you try connecting via AFP directly? So command+k, afp://<ip addr> ? Could be something not working with the mDNS...that happens sometime at my house, I just have to connect directly.

Yeah, I've tried AFP and also FTP I think. None will work. But they will work when he connects to me. Do you think it's a problem on my end, or his... or is it just some kind of network problem?

On MIni,
Check firwall setting
Check sharing setting

Thank you sir, it was the firewall settings.
