SUMMARY
When you install Windows 2000 SP1 (MDAC 2.5 SP1) or Windows 2000 SP2 (MDAC 2.5 SP2) on a system that has MDAC 2.6 installed, the resulting system configuration will have MDAC 2.6 still installed along with updated Microsoft Jet components.



MORE INFORMATION
Possible installations and their resulting MDAC and Jet versions are as follows:

Windows 2000 + MDAC 2.6 -> install Windows 2000 SP1 = MDAC 2.6 + Jet 4.0 SP4

Windows 2000 + MDAC 2.6 -> install Windows 2000 SP2 = MDAC 2.6 + Jet 4.0 SP5

Note Windows 2000 ships with MDAC 2.5 and Jet 4.0 SP3.
