I have the same issue.
The system had been running just fine for 6 weeks. ! Yesterday I had to revise my HDD RAID1 configuration (increase the operating system space). This erased all my applications & data so I reinstalled Vista and received the message "Compatibility issue between windows & chipset....Intel quickpath architecture input output hub". I did not install the linked fix because the version on my machine was newer.
I'm now having internet connectivity issues.... can't establish & maintain connectivity. Thunderbird mail client isn't able to install a new update, etc.
Also can't get my LAN to recognize the 2 computers (each computer can recognize the network attached storage – NAS).
Saving files, etc. is much slower than previously.
I wonder if a recent Vista patch has caused this issue?
