How To Give ASPNET Account Permission To Access DB's

I'm creating one of my first asp.net pages, and it accesses an MS SQL database.It runs fine locally, but if you go to it remotely through a web browser, you get an exception saying that the database login failed for user ASPNET.My brother told me to do the following in SQL Server Managment studio.  It seems I don't have that program installed, so I did it from the SQL command prompt.CREATE LOGIN [bigblueASPNET] FROM WINDOWSuse AdventureWorkscreate user [bigblueASPNET](Where "bigblue" is the computer name and "AdventureWorks" is the database my asp.net web page reads from).This only partially fixed the problem - now when you open the page remotely and try to access the DB I get an error message saying that permission to use the SELECT command is denied.I searched on these forums, and found this:http://forums.asp.net/69166/ShowPost.aspxFor future reference, let's call what my brother told me "Method 1" and what the previous poster did as "Method 2."I haven't tried method 2 because I don't know exactly what I am giving ASPNET permission to do.  Does method 2 enable ASPNET to do anything to any database?  It seems method 1 is more secure, as from the commands I could already tell it only has permission to access AdventureWorks.So, I'd prefer to use method 1.  Can anyone tell me what further commands I can use to give ASPNET permission to do specific actions?If I can't figure out method 1 and have to do method 2, how can I undo what I did in method 1?Thanks!
