How do a get a listing of all available SQL Servers on a network.

I want to create a web app that will allow a user to select from a drop down or lookup all available SQL Server databases.

Thanks in advance,
Jeremyi answered my own question... hope this helps some one

To restate my problem.
I need an app that will list all of the available SQL Servers on a network. There are many ways to do this ... this is one. I would like to see better ways if anyone has time.

1. Download the SQLUtils.dll from (watch for line wrap)
http://codeproject.com/useritems/listsqlservers.asp?print=true

2. Register the SQLUtils.dll using regsvr32.exe
> regsvr32 c:/inetpub/wwwroot/lib/sqlutils.dll

3. Build your web form

// C#

using SQLUtils;

protected System.Web.UI.WebControls.TextBox TextBox1;
protected System.Web.UI.WebControls.Button Button1;
protected System.Web.UI.WebControls.ListBox ListBox1;

private void Button1_Click(object sender, System.EventArgs e)
{
SQLUtils.ListServers oSqlUtils = new SQLUtils.ListServers();
// String svr = new String();
oSqlUtils.Domain = TextBox1.Text;
oSqlUtils.GetSQLServers();
foreach( String svr in oSqlUtils.Servers )
{
ListBox1.Items.Add(svr);
} // end of foreach loop
} // end of Button1_Click()

4. You will need to add a reference in your project to the .dll file. Right click on the project and select "Add Reference". Browse to the location and select.
