Thanks for the response. I am a newbie to MSDE and .NET and am not quite sure how to add 'ADAIR001\ASPNET' to the db and give it permissions. Will have to look into that, but if anyone can help me out by posting the solution or a link to useful info that would be greatly appreciated.
Also, I am puzzled by the fact that I was allowed access to the database when using Winforms. Why do I need permissions all of a sudden to use Webforms?
