exception errors on all dotnot

[Scott Harman]

I've had to install the MDAC 2.7 updates to get my Win2k machines back up
and running .net based applications - but a couple of users (including
myself) are using XP Pro SP1a.
I've reinstalled the service packs, but had no joy getting the applications
(any of them) up and working again.

Does anyone have any suggestions on how to fix this?

Cheers,

Scott
