Help rooting slide

I've been rooting my slide for a cumulative of about 10 hours. Most of that is because I'm using a Dell dimension 2300 whatever. I had to format the C: again to even get it to work then load updates and .........holy crap. What a weekend.
I came to a stopping point though. Does anyone have any idea why, in the command prompt, when I get to "exploid" it say's the file does not exist. But when I go into androidsdk tools. there it is. I think it may have something to do with not being a file type with no program associated to open it (by the look of the icon) Is there a particular program I can download/open to associate to this exploid file? Any help greatly appreciated.
