Reinstalling MDAC on Windows Server 2003 SP1

[Nick van Ogtrop-de Ruiter]

I am confronted with an issue on a recovered Windows Server 2003 server
whereby the MDAC installation appears to be corrupt. The server in question
has been recovered by booting to a 2nd Windows installation, and as a result
I fear there is a discrepancy between MDAC files in the Windows folder
(C:\WINRESQ) and those in the Programs folder (C:\Program Files).
I've run the ComponentChecker and this also finds mismatches, or at least
files from 2 MDAC versions (MDAC 2.8 RTM & MDAC 2.8 SP2 on Windows Server
2003 SP1). I suspect the Programs folder files will potentially have been
updated whilst the server was running with it's previous installation ...

What am I wanting to do ...?
I am attempting to install McAfee Protection Pilot on this server, using an
MSDE instance on the same server. MSDE installs correctly, but when I try to
to access the database during the installation of Protection Pilot (using a
valid domain account with sufficient privileges) I get an error referring to
a missing DefWindowProcI call in MSDART.DLL.
The server is running SP1 with R2 components, and I have tried to reinstall
MDAC (the only available download version is 2.8) but the problem remains. I
am hesitant to attempt a reinstall of Server 2003 SP1, or even SP2, for fear
of breaking even more.

Any assistance would be greatly appreciated.

RE: Reinstalling MDAC on Windows Server 2003 SP1

After having been confronted by various issues relating to Windows File
Protection, I have now resolved this fairly simply by copying the contents of
the \Program Files\Common Files\System folder from a correctly functioning
and updated Windows Server 2003 SP1 system to the same destination folder on
the faulty system.
This has removed the discrepancy between the various MDAC files, and the
Component Checker now reports only MDAC 2.8 SP2 to be installed.
