Hey Don,
I made sure MDAC is installed. Ofcourse it was because the site is full of ADO requests which all work fine.
I then added an app.master file to the site root. I attached a copy of it. Not sure is this is what you wanted for contents.
However the same behavior is still happening.
Please advise what to try next.
As I stated before the same site is working perfectly well on a different server.
Thanks,
Yury
