Is this problem still not solved? I'm using Windows 7 Professional 64-bit and I still cannot connect my Windows Media Player to my 323 UPnP AV server...
It won't. Return it if you can. Even though on the box it says "Can connect to DLNA/UPnP devices such as PS3, XBOX...", etc etc it does not mention Win7.
I have an email from a DLINK support staff saying that since the statement does not mention Win7, they are within their rights not to accept returns. I find this false advertising, as they should have stated that it only exclusivly stated it was for those devices only. SUCH AS is a cop out. Win7 HAS DLNA/UPnP built in, so the SUCH AS still fits. It also happens to be the most prevailant OS on the planet.
Anyway, I brought mine back and got the ReadyNAS Duo, which ON THE BOX STATES IT SUPPORTS DLNA/UPnP for WIN7. If I was you and wanted DLNA get that. If you don't, then the DNS-323 is fine as a file server.
DLINK, get your act together and properly advertise what this product is capable of.
My 2 cent rat.
