The Nuclear Option: Resetting The Crap Out Of Your Network Adapters in Vista

Posted 2007-09-20 03:31 PM in Musings.

I was having a number of strange network issues on a laptop today. Here's the complete nuclear option for resetting your whole IP stack. This is for when "Diagnose and Repair" isn't cutting it. Thanks to JohnP for his help.

Go to the Start Menu, type cmd and right click, and select "Run As Administrator"
Type the following commands, each followed by pressing enter.

ipconfig /flushdns
nbtstat -R
nbtstat -RR
netsh int reset all
netsh int ip reset
netsh winsock reset

Now, reboot and pray. Possibly not in that order.

Another command to resolve Vista networking issues. I had to do this in order for TortoiseSVN to work through SSH.

netsh interface tcp set global autotuninglevel=disabled

After typing cmd you can hold Ctrl + Shift and hit Enter to run as Administrator, its way quicker!

I seems like your problem is the use of Vista. Perhaps you should downgrade to a more stable OS.

Great! Thanks!

Why is it we can't trust Windows to actually repair anything? Repairing software almost never solves the issue, and neigher does repairing a network connection.

I have had recent difficulties on XP and Vista with network access. Both times I found that the Microsoft TCP/IP version 6 protocol was installed on the network interface. After unistalling, my network connection began working again. Not sure if its Microsofts TCP/IPv6, or just my older MS Wireless Router having an issue with TCP/IPv6? Also, I don't remember installing TCP/IPv6 -- maybe Windows Update?

I've found that this happens with great frequency on two of my three Vista machines. I keep a shortcut to Control Panel\Network Connections on my desktop, and actually have to just click on the net adapter having issues, click "Disable", wait about 10 seconds (the waiting is key, alas), then click "Enable". This fixes the issue almost every time (about 1 in 10 times I do need to reboot as well).

All in all, yes, I think the IPv6 stack needs some additional debugging. Having written a custom TCP/IP stack, I completely sympathize with the proto stack dev team at MS. IP is a foobugly protocol to implement.

Cheers,
Mike

Thanks!

I just had to reboot because of Network issues... I Did remember reading this, but after the Network was down, I had some issues reaching this resource ;)

I made a small batch file so I can try it the next time it happens (And it happens quite regulary)
