MSN slows down File Sharing

hi there........

I have figured out why my network transfers are slow on my Gigabit network...

Basically I am transferring files from my server running Server 2003 Enterprise R2 SP2 to my Vista Ultimate x64 machine over my Gigabit network.

Before I open Live Messenger, I can get 40-50MB/s, but as soon as I open Live Messenger, I can watch the speed drop quickly until it bottoms out at like 10MB/s. As soon as I close MSN, the speed beings increases again.

I have tried disabling QOS and IPv6 on my network connection in Vista along with AutoTuning and Receive Side Scaling via netsh. None of that had any effect.

Then I thought may be it was just MSN so I tried Pidgin and the same thing happens...

So anybody else with this issue or knows of a fix?

Please provide some suggestion regarding this.............

Try using some other messenger and vary the speed of your internet as per previous you record it regularly

Thats odd... its possible its one of those built in QoS things in Vista, thats meant to give you a good 'media' experience and prioritize things like Music and Video, and will slow down your connection to do so.
