At this point I am not changing anything in the connection string, since tons of other desktops work fine. And I don't have access to the "offending" desktop so I would not be able to check anything. Not that I would even attempt to look at the registry. The IT is not screaming "bloody murder" which tells me that he either does not blame my app or find that this PC is not no 1 priority. I will let him "deal" with the guy who made the change, first. Then I will work with him on various changes.
