Hi, JNapier010.
Triggering the script is simple, but mapping drives with it is impossible. You can trigger code on a web page by using the OnLoad event of the page's Body. But, script on a web page cannot do things like map drives. If that were possible, then surfing the Internet would be even more dangerous that it is now from a security perspective. That's mean that any site out there could add code to a page that'd map drives, collect information, etc. It is possible to run code from a page and have it do things like map a drive, but that only works by putting a link to the code on the page and having the user click it. They then have to select Run from the security dialog before anything happens.
