Hey Folks,
I am getting the following errors when I try to connect to my db with
the MySqlConnection. I added MySql.Data to my Reference list and have
the .dll in my bin directory. I also have "using
MySql.Data.MySqlClient;". I know it's not my connection string because
it works when I use an OdbcConnection. The error points to this line:
MySqlConnection conn = new MySqlConnection(ConnString);

Hello,

tested on IE 6 on different setups and IE 5.5 to a lesser degree without
problems.
I know of a least one user who gets an error in WebResource.axd when using
the application. The same error also occurs on a simple reproduction page

Our IT team relocated our application servers yesterday. They had to take
one machine out of the cluster because it would prompt users for credentials
if accessed using the IP address, which I guess is what happens when it is
accessed through the firewall. However, it works as expected when I use the
machine name in place of the IP address.
To summarize, the application servers were moved to a new hosting site and
one machine is...
