Changing IP address via Batch File

I frequently have to change the IP address on my laptop to access various network devices that I'm configuring.

It wasn't so bad in Windows XP, but in Windows 7 it takes far to many clicks for something I'm doing around 10 times a day.

So I decided to make a Script I could just click to allow me to set the IP



Poking around on the internet, brought me to these two sites:
http://community.spiceworks.com/how_to/show/320-batch-file-script-to-change-ip-addresses
https://sites.google.com/site/eneerge/home/BatchGotAdmin

The first link is the basis of my script (I liked being able to just type the IP i wanted, instead of keeping different batch files for different configs.

The second one was important to make it work on Windows 7 without having to manually select "Run As Administrator"

First, make sure your Network adaptor is named LAN.  Otherwise, change all instances in the file of "LAN" to the name of your network adaptor.

I've modified this to include DNS.

Save this to notepad, and change it's extension to .bat.

• UPDATE 9/25/2014:  Added the continue quit section at the beginning, cause sometimes I don't know what IP I have, and just clicking this on my desktop is much shorter than launcing a cmd prompt and doing an IPCONFIG, or going thru the GUI and finding the interfaces status
• 1/5/2015:  Since I added the IP address section, when you select continue, it must restart the script, so you'll get the do you want to continue twice.  I have an idea on how to fix this, but no time to implement / test.  Later we hope (I just plan on adding a root detection at the beginning, and if it's true, skip the question)
• 3/11/2015: Added the root detection, so now it skips the question.  I also added an option C, Static IP without DNS, since most of the time I don't need it.
