Answer 1

I decided to put as answer so it doesn't become a chat.

Yes, most of time the account that IIS run on is high enough to access any files on the computer or at least a dll you might have made that connect to your database.

You can easily connect to file c:\\MyOfflineData\\db.mdb (lets say access for sake of example) all you need is the proper ADO connection string. It works as well as any other connection.

Also BTW you do NOT need to have your SQL server open to the internet. For example all my setup have always been like this :

1 server with IIS and all my Web service opened to the internet

1 server with SQL that is only internal and have no internet access.

my services can connect to the SQL since it's on the network and can do whatever i want but no one from outside can see my SQL server. so technically my whole SQL server is "Offline" as you call.
