Fun with Powershell – Network connection reset

I realized that I have never posted one of the Powershell commands (or scriptlets) that I use most often. I use a lot of VMs for my every day development work. Often, the virtualized network connection can get out of whack with my physical network connection. So, I find myself running these three commands over and over:

ipconfig /release
ipconfig /renew
ipconfig /flushdns

It’s somewhat of a “scorched earth” approach to network issues, but it’s short, quick and it seems to work fairly well. I realized that these three commands are the same except for the parameter passed into ipconfig. So, now I just fire up Powershell and fire off this one liner:

@("release", "renew", "flushdns") | % { ipconfig /"$_" }

I’ve turned this into a function in my profile (Reset-Network), but I often forget it’s there and just type the whole thing, since it’s so short.

Anyways, short and simple, but pretty effective. One more reason I’m enjoying playing with Powershell.
