Hey kano650, i have a similar problem, but i can add to that. I have four (4) Linksys Extenders (DMA 2100/2200) and two (2) Xbox's. On all four extenders, i can not get the Pictures and Music Library to connect to my HP Mediaserver (where everything is stored and duplicated). One of my Xbox's will display everything, including the Music and Pictures from the Mediaserver???? I just bought my daughter a brand new Xbox and it is exhibiting the same problem as the extenders. I think i have tried everything. Oh yea, my HTPC that all of the extenders and Xbox's are connected to will display everything!
I'm getting a bit desperate...Anybody have ANY ideas?
If it helps, yes. Everything worked perfectly before November, when strange things started to happen. All of the extenders and the Xbox worked fantastic for two years!
