Upgrading to Office 2003

Here's the problem: I want to use Group Policy to deploy
Office 2003. I tried it and it won't uninstall Office
2000 completely. I used Microsoft's resource kit to create
an MST file, I added the Key, and I made it so it would
completely remove Access and FrontPage 2000, because
Office 2003 standard doesn't come with that. I created an
OU and added a new GP. I located the MSI file within
Office 2003 Standard folder and advance assign the
package, I located previous GP that had Office 2000
package and added that as an upgrade and to uninstall, I
added MST file to modifications tab. I added the Computers
to OU and restart computers. When the install was
finished I found out that Office 2000 wasn't removed, I
could still use Access and FrontPage so I had to manually
remove Microsoft Office 2000.Any suggestions?
