So choose System DSN and click on "Add"
At this point, it'll ask you for which driver you want to use. Since you'll be connecting to your project database, you'll want to choose SQL Server. So select "SQL Server", and click finish (no, of course that doesn't mean that you're done). Next you'll want to specify which database you want to talk to. You'll see a dialogue box with three boxes for you to fill in. Pretending that I'm a member of the group "entities", I'd fill them in appropriately:
Click next and choose that you want to connect with SQL Server authentication as given to you by the administrator. This is very important, because otherwise you'll be the only ones able to access the database.
Click next and choose that you want to connect with Windows NT. We'll be sending you mail with your username and password. Each group will have one username and password per database. Note that it's important to create this entry with exactly the same database name, login id and password that we gave you, otherwise when you try to connect on the server, it will not work.
Now click "Next" again, and it'll contact the database to makesure that you have the appropriate permissions. Make sure that you have your group's database selected as the default database (it shouldn't be a problem for you, because you have permissions for one database on ISQL01, so it should figure that out automatically, but check it just in case).
Click next again, then finish, and finally, click "Test Data Source" to make sure that everything ran properly.
Note that this step should only have to be done once (when you actually create the ASP.NET project), but if you run into problems, it may need to be done again.
After you link the tables to Access, you can insert/delete/update tuples in the database in Access.
