I am using Win XP, IIS, Sql Express 2005 and VS .Net 2005 Standard.

In VS I can login with the account "dave" but when trying it from: http://localhost/wroxunited I receive this error message.

"Your login attempt was not successful. Please try again."

I have "Network Service" with permissions: Read & Execute, List Folder Contents, Read, Write on the App_Data directory.

What can I do to fix this?

I fixed it...
I added to the WroxUnited directory the ASP.NET account with allow Write.
To do this:
- Right click on WroxUnited and select Sharing and Security
- Select tab: Security
- Add button
- Addvance button
- Find Now
- select ASPNET
- Ok
-While ASP.NET is highlghted the bottom half display the Permissions for ASP.NET. Select from "Allow" column the Write permission.
- Ok, your done. :)
