Thanks, Ken. I did, in fact, document the errors/connection strings in
reverse.
The sa account does have a password and I forgot to include that in the
connection string.
Adding the password fixed my problem.
Point taken about using a less privileged account for SQL Server access.
Security is a little sloppy around here because this is a closed Intranet
behind a firewall (and a 2-person company).
Thanks for your sage advice.
