I'm seeing some weird network problems on one of my machines, and I need some input :)
I have a host machine running Windows Server 2008 R2 and the Hyper-V role.
I have several guest machines running on this host including Windows 2008, 2008 R2 and one Windows 7.
On the 2008 and 2008 R2 machines network and internet access perform as I would expect. I have a 30/30 Mbit/s connection to the world.
However on the Windows 7 machine I get "extremely" slow upload speeds. Around 1 Mbit/s (100 KB/s). This is only when uploading to sites on the internet. Local network transfer between physical and virtual machines perform as expected. Download speeds are also fine, it's only upload to internet sites that perform badly.
Any idea what might be wrong?
