SQL 2005 and XP Mode

I want to run an application in Win 7 using XP Mode that connects to a SQL 2005 database loaded on the Win 7 host.

I either get an error saying it can’t find the server or that it can’t connect using Named Pipes (error 40).

I’ve made sure that the SQL Server is allowing remote connections and that Named Pipes and TCP/IP are both selected. I also started the Browser service.

I turned off the firewall in both environments.

Any idea how to get an app in XP Mode to see SQL Server in Win 7?
