I would like to mention my last topic about database connection.
I found this solution for my problem. Because XP SP2 did enable firewall after installaiton. So I couldn't see tables in my database from Application panel.

"Database connectivity fails with local ASP.NET and ASP servers
ASP.NET issue: When using a local ASP.NET test server running on XP SP2 with Dreamweaver (i.e. the Testing Server URL prefix is set to "localhost"), database connectivity fails. If you click the Test button in the OLE DB Connection or SQL Server Connection dialog box, it says the connection was made successfully. However, if you then try to browse the tables in the Databases panel or in the DataSet dialog box, the database tables do not display.
ASP: When using a local ASP test server running on XP SP2 with Dreamweaver (i.e. the Testing Server URL prefix is set to "localhost"), and you specify "Using driver on testing server" or "Using DSN on testing server," database connectivity fails. If you click the Test button in the Custom Connection String or Data Source Name (DSN) dialog box, it says the connection was made successfully. However, if you then try to browse the tables in the Databases panel or create a recordset, the database tables do not display or you get the following error message: "Unable to retrieve tables from this connection, click on the 'Define...' button to test this connection."
Workaround: Download and install the Dreamweaver extension fix by Macromedia that resolves this issue (Ref. 179021). To use this extension, follow the steps below:
In Dreamweaver, select Site > Advanced > Remove Connection Scripts.
Install the extension.
Restart Dreamweaver and create a new database connection.
