Updating MDAC to the latest version will help depending on what pages
these errors are coming on. If the error message appears on any page
which contains girds (tables that contain information) then we might have an
MSADC problem as well. But the MDAC component is used when pulling
information into Project Web Access girds.
But you might want to check if the MSADC virtual directory has the correct
settings configured in the IIS manager. I wish I could be a little more
descriptive on what settings you need to check, but I don't have an IIS box
with Project Server installed to review. But in the virtual directory propertise
dialog, the Application something needs to be "something" and excute
permissions. My memory is that sharp to remember it all.
Hopefully that helps too.
