We just upgraded to Vista from XP and on some PCs get an error message
about MSRDO20.dll not being installed when I try and connect to a
SYBASE database using ADO.
I have asked the technology group for help installing this (some PCs
have it, some don't)

My question is - fromteh VBA Developer screen (inside Excel) under
Tools - References - which referneces do I need to include to be able
to use ADO?

What I'm wondering is if in Vista there is a reference I should add in
that I have not used before.

Is it sufficient that I just downlaod MSRDO20.DLL from the internet
and hope it installs/registers correctly? Is that all thats needed?
