Here is the error I receive when trying to create a data source in front
page to create a data view web part:

Server error: an error occurred while retrieving the list of databases
from vuls-photo01: the web server cannot connect to the specified data
source because the query may contain errors, the data source may be
unavailable or configured improperly, or your web site is behind a proxy
server or firewall.

If your web site is behind a proxy server or firewall, verify that your
server administrator has configured the data retrieval services http
proxy server setting for Microsoft windows SPS services.

I am able to connect to the data source from any machine on the network
by creating an ODBC connection without problems.
