Lockout the start menu in guest account in XP Pro???

I have tried to look through a few threads to see if there was anything posted, but I need to know how to lockout the start menu from a guest account and make it accessible by the administrator only. I have 250 student laptops that use an active desktop tool for their class and I need to heavily restrict their access to everything else. Any suggestions??? Oh yeah, its in XP Pro.

Thanks,

not sure if you can actually disable the start menu itself, but here is a link to use policies or edit registry settings for most everything on the start menu. It gives both the security policy setting to disable and the registry key

Microsoft Knowledge Base Link

that is what I am working through now. But I have been told that there is a way to lock the start menu entirely.

The only thing I can think of offhand is possibly changing the permissions or set "Read Only" the "C:\Documents and Settings\User Name\ntuser.dat" file, corresponding to the particular guest account (be careful with this...I've never personally modified the NTuser.dat file, so I can't verify it works). I don't think there's a way of locking out the Start Menu for only the Guest account, using either the Group Policy Editor or Local Security Policy. BTW, NTuser.dat (and its backup NTuser.bak) are the part of the Registry relating to your account...it's loaded by the system when you logon.
