Connecting to mysql server on LAN cannot pull database

Hey all.

I have an application that i moved from the main database computer to
another computer. So, the only line i should need to change in
database.yml
would be the host line, i think.
However, i cannot get the application to connect. It seems able to
connect
to the database, but the error i get is that the database does not
exist.

i have other scripts that can connect to the same database that use the
mysql gem, and there seems to be no problem.
any ideas?

ruby 1.8.7
rails 2.3.5

thanks
