error installing adminpak.msi

[JMRIEMAN]

I am trying to install the adminpak to a Windows 2000 SP3
workstation. I am logged in as local admin and have tried
installing from the Server media and also from the
C:\WINNT\SYSTEM32 directory. I receive a prompt to insert
the SP3 CD in the drive. I have tried to install the
ADMINPAK also from the extracted i386 directory from SP3.
See error below
