***This there was posted inanother forum, but went unanswered so Mark Ferguson suggested moving it here.***I wasn't sure if this belonged in the networking forum or here, so I flipped a coin and this forum won. (Or lost, depending on your particular outlook.) Anyway, I have been attempting in vain to diagnose & resolve this problem - Win7 is the host, and Vista/Xp boxes are the viewing stations. The drives on which the media is stored are RAID0, network adapters are gigabit for wired boxes and Dlink Extreme N for wireless - the router is a Dlink Extreme N multiport Gigabit router. - when attempting to stream video or audio from the Win7 box, it is garbled and ungodly slow, making any viewing or listening experience far less than even slightly viable. Sometimes it starts out okay, running well for 10-30 seconds and then just bogs down to a trickle of data every 5 seconds or so. I've tried making changes to the way QOS works, MTU levels, ports, and things of that nature, but have yet to see any improvement at all. I don't know if it is a compatibility issue with my router or something in the tcp/ip settings or what, but it is kind of frustrating. I've also tried streaming the same files *to* the Win7 box with no positive change. Additional PD - streaming with DRM enabled and non-DRM enabled media = No Change streaming from the Xp and Vista boxes to one another = Success (Leaving the Win7 box out of the equation.) defragging the Win7 hard drive = No Change converting files to WMV & WMA = No Change connecting to an older 10/100 router (Linksys) = No Change I've also noticed thatsimple file transfersbetweennetworked Win7and Vista/Xp boxes is just as slow, andmost of the time fails altogether. It leads me to believe there is a pretty serious networking bug in this current version of the beta.That said, if anyone hasmet with success in streaming media between multiple o/s' from their Win7 box, I'd love to hear how you did it. -jay

Maybe you should start to inspect the network trafficusing Network Monitor, available as free download from http://www.microsoft.com/downloads/details.aspx?FamilyID=f4db40af-1e08-4a21-a26b-ec2f4dc4190d&DisplayLang=enwatch out for collisions and reties and possible delay's in packet forwarding.What driver are you using for your NIC? the Inbox or a upgrade from the NIC vendor? What's the vendor name?

The NIC driver is the oob driver. The mobo is a Nforce 650i and no, there are no working chipset drivers from Nvidia as yet which will work correctly under Win7. I haven't yet run an external netmon program but will try to get to that tonght. I've no doubt the problem is with Win7, given the results of previous PD as listed above-the issue now is to narrow it down to WHAT in Win7 is causing it and HOW to fix it. Hopefully the netmon will provide some sort of answer.-jay

I have had similar experience with Nforce chipsets and onboard NICs. Try a different NIC.Kerry Brown MS-MVP - Windows Desktop Experience

Kerry, I popped in an older Intel 10/100 card and while Win7 did, indeed, recognize the card immediately and internet connections as well as connections out to the rest of my networkwere working, the issue of slow/unviable streaming did not go away. :(
