I need some help here, I have an asp.net page that connects to a DB. I can connect to every DB that came installed in SQL 2000, but when I try to connect to a DB that I create I get a login failed error message. Cannot open data_base_ requested in login dbname , Login failed for user servername/aspnet I get this with any db i create but i can use the same code and the db's are configured the same with the aspnet ID and can connect to pubs, northwind db's fine. what i'm i missing or doing wrong?
