I don’t know how to do “Give user ASPNET and NETWORK SERVICE Modify control over the App_Data directory. (I had to add both these)
3) Run IISRESET to restart IIS to refresh its permissions.” steps

Oh yes!
Did a website deploy and after I copied the files (including MDF) the “DB is readonly” error was displayed.
Thanks!

I encountered the same problem with a Windows application on Vista after applying SQL Express SP3. For some reason, the account used to access the database no longer has write access to the database. To overcome this, I manually granted write access to the Windows Users group on the database. That seems to do the trick, but I’m not sure whether it’s a good security practice.
