Have you tried them in Safe Mode with Networking ?

I'm just wondering if your antivirus program could be the problem which will be isolated in that mode.

I don't think there's much point in running the MDAC repair in the repair program as that Test_MDAC.exe came back clean.

That's unwise, but all 3rd party programs will also be isolated in that mode as well.

There may be something in this article that will help but it may be better if you use MS support for this problem.

ok i'll try on microsoft support, but i think that something is not clear here, provider exists, database open, but crash on query!

Well something is conflicting.

Safe Mode with Networking isolates all 3rd party programs that may be starting up when you boot because they are in your Startup menu in msconfig.

What is common to both modes is Windows Firewall, but I would have expected an Access Denied error code if that had been the case, but should it be because of Windows Firewall, have a look at this article for adding Outlook as an exception.

As usual though, create a restore point before making any changes.
