Yup, it's possible with a shortcut.
Here's what you do.
Make or copy one of the shortcuts to Internet Explorer (on each computer).
Then right click on the shortcut and go into the properties.
For the Target it should look something like this:
"C:\Program Files\Internet Explorer\IEXPLORE.EXE"
Change it to this
"C:\Program Files\Internet Explorer\IEXPLORE.EXE"
Notice all I did was after the last quotation mark, add a space and then the URL of the webpage that I want it to go to.
At this point you can rename the shortcut to whatever you want and/or change the icon and other stuff if you like.
Basically what it does it launch internet explorer but with the command line option to have it launch with a certain page. I got this idea based on something I read elsewhere that told you how to set up IE so it launches with nothing showing (to speed up launch time a little).
There is a problem with this - as you can see the shortcut uses an absolute URL to Internet Explorer. For that reason you might not be able to creat just one shortcut and put it on all computers since they may have IE installed in different places. Then again, there's a good possibility all of them have IE intalled in the same place so....
If this is a problem or if you know a better solution post again.
