One of my friends and Trouble Fixers reader, Ashish Chopra, a true geek by nature, shared his troubleshooting experience with us regarding a BSOD – Blue Screen Of Death problem faced with Windows 7 64 Bit Enterprise version after he installed uTurroent or µTorrent on his Lenovo Thinkpad laptop. µTorrent is a popular torrent client software for Windows which is used for downloading content using torrents. In this article, we will share the problem he faces and the solution to the problem. We thank Ashish for sharing this information with our readers.
For a few months, I was unable to use uTorrent on my Win 7 Enterprise (64bit) Lenovo T420s (Product #4174-CS2) even after a reinstall and all Lenovo-only drivers/softwares. Every time I ran uTorrent, it BSODed with following error.
DRIVER_IRQL_NOT_LESS_THAN_OR_EQUAL on netio.sys
Many forums like the following recommend running Driver Verification to see if there was an offending driver causing BSODs, Disabling/Uninstalling Antivirus Softwares, downgrading to a previous version of uTorrent and the likes, but yet I found that none of these solved the problem I was facing.
I went on and started to examine Windows event-log to see the events just before the BSODs. Turned out then almost every time, it involved an IPv6 network packet reception.
Then, after a few weeks, I suddenly noted that uTorrent logged a message about Teredo having initialized and running – which made me disable Teredo and viola! The problem was gone!
Steps to Disable Teredo
Step1: On start menu, search cmd, Windows will locate the cmd.exe which is command prompt, right click on it and clock on Run as Administrator.
Step2: On command prompt, type the following command and press enter
netsh interface teredo set state disabled
This is it, its done. Hope you find the above tip easy to follow.
