Deploy File System Web site

[paps]

hi i've a file system web site with a SQL Express DB stored in the APP_Data
folder and created with the aspnet_regsql utility.
On mu local machine every thing work but when i publish the site to a remote
webserver on IIS i recive some errors (when i call the default page) :
1) ASPNET (user) cannot access to the Sql Express DB in the App_Data folder
2) if i give the permission to the ASPNET user (on the remote machine) i
cannot authenticate with any users (with the same db data i do it in local)
"User not found"... but the user is recorded in the Membership table
3) it's possible to use the VS site Administration on the remote website ?

Thanks for help and suggestion
