Web Config Connecting To SQL 2000

Hi all,

 I'm having a frustrating time connection to SQL 2000 from the web.config. I'm getting the following error

 Here is my config

<?xml version="1.0"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
 <appSettings/>
 <connectionStrings>
 <add name="ConnectionString"
      connectionString="Server=xxxx;Database=xxx;uid=xxx;pwd=xxx;"
      providerName="System.Data.SqlClient" />
   </connectionStrings>
 <system.web>
  <compilation debug="true" strict="false" explicit="true"/>
  <authentication mode="Windows"/>
 </system.web>
</configuration>

This is the error i get

 An error has occurred while establishing a connection to the server.  When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

Any thoughts?

Thanks.
