Wrong order. Registerdns registers your current IP. When you release and renew, you can get a different IP back. You want to do the registerdns after the renew.

To what end?

Or just yank the power cord out of the wall.

First, that's the craziest overreaction to a simple need to reboot I've ever seen. Second, this is useful for people who have servers/VM running with a networking hang.

Also never a bad idea to also run: netsh int ip reset

Haven't had to use this for like a decade, but this used to fix all kinds of weird networking issues in like...windows xp.

Pro tip: ipconfig /release && ipconfig /renew

Pro-tip: 99.99% of the people that read this will never need to use either of these commands.

I work in IT so I've used both (a lot) but most consumers will never need to run those. Rebooting is almost always a better idea for the average day-to-day end user.

Was thinking Win 2K.

both of us are way off, based on the version output in the first line. Either Win 7 SP1 or Server 2008 R2 SP1.

Yeah, I was too busy just reading each command and trying to figure out how long it's been since I've needed to run some of them.
