Linking To SQL Server 5.0

I'm writing my first web site using VS 2005 and with my login page I'm trying to link with my SQL database using the following setting in my web.config file

<appSettings>
 <add key="SQLDB" value="server=STEVE-LT; database=MasterDB; uid=sa pwd="/>
</appSettings>


Then in my Login.aspx file I use the following code to access the SQL database

Dim Sc As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.AppSettings("SQLDB"))
Dim SqlCmd As SqlCommand = New SqlCommand("Select Password, Name from Login")
SqlCmd.CommandType = CommandType.StoredProcedure

Sc.Open()
SqlCmd.Connection = Sc

 This raises the following error message

A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)

Could someone please tell me where I am going wrong. Thanks
