Connection string for 2 databases on different servers in vb.net

Hi all.

I have the following code that populates a datagridview control in Visual Studio 2010. The problem is that my Select statement needs to join 2 tables from different databases and different servers. How can I make this work?

As you can see currently, my connection string only references db1 on server1.

server1, db1
server2, db2

Dim con As New SqlConnection
        Dim cmd As New SqlCommand

        con.ConnectionString = "Data Source=server1;Initial Catalog=db1;Integrated Security=True"

        con.Open()

        cmd.Connection = con
        'cmd.CommandText = "SELECT  MasterItemNumber, Description, SLXID, QuoteDate, UnitCost, QuotedCost, Notes FROM ItemQuote WHERE MasterItemNumber = @MasterItemNo"
        cmd.CommandText = "SELECT  MasterItemNumber, Description, SLXID, QuoteDate, UnitCost, QuotedCost, Notes FROM ItemQuote INNER JOIN db2.sysdba.ACCOUNT ON ItemQuote.SLXID = db2.sysdba.ACCOUNT.ACCOUNTID WHERE MasterItemNumber = @MasterItemNo"

        cmd.Parameters.AddWithValue("@MasterItemNo", txtMasterItemNo.Text)

        Dim sda As New SqlDataAdapter(cmd)
        Dim dt As New DataTable()

        sda.Fill(dt)

        Return dt

        con.Close()
