I need help setting up media server with WMP 11 and PS3 .

Right I have tried everything for a while now to get this working , every-time I follow steps from forums and web help pages . My PS3 never finds my WMP11 as a server , on the ps3 I have set media share as active on WMP I follow the steps but when I click ok nothing happens apart from a small freeze . OK this isn’t a big importance as i use other form of stream , but I would rather use WMP as Sony say its the best suited for PS3 . I just need help cause everything should work but it doesn’t , here is one site I tried http://www.digitaltrends.com/gaming/playstation-3-media-server-setup/2/ note the picture names ’ media sharing in WMP11 ’ this never happens on my WMplayer
Maybe you know a better one to use and can tell me how to set it up , the one i use is TVersity but it gives alot of DNS errors ( this is normal according to them , I just don’t like it happening )
