Problem after moving ASP.NET and ASPNETDB membership db to different machines

On my XP developer workstation:

I have a properly running ASP.NET 2.0 web site implementing forms based authentication and I am able to login fine.  For authentication I used the membership APIs  - I created a SQL Server 2005 database called ?aspnetdb?using the aspnet_regsql script. I created roles and users in aspnetdb using the WAT tool in Visualstudio2008.  I have 1 user in the aspnetdb called ?User1?.  I am able to successfully logon using the User1 ID - on my XP machine.
