Did you upload your web.config? The ConnectionString is stored there.
You should have at least this in it:

<?xml version="1.0"?>
<configuration>

<connectionStrings>
<add name="SalesOrderConnectionString" connectionString="......" providerName="System.Data.SqlClient" />
</connectionStrings>

</configuration>


Good luck,
Jeff
