First off I would like to say that I am new to asp.net and programming in general. I have created a website that is being hosted at Network Solutions on a Windows server. My html and aspx pages load fine. On my aspx pages I am using the asp login control and the create user wizard control which is using a SQL Server back end to store the data. On the hosted aspx pages when I click on the button to login or create a new account I get the following error:

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

This does work locally on my dev machine. Network Solutions is absolutely no help with this at all.

Please help. I have been batteling this for a week and have missed my deadline. Any suggestions on fixing this issue would be great.

Thanks.

Thank you very much for your reply. I have all of the code you suggested in my web.config file already. Even with that in the file I still get the error. Someone in another forum suggested using the following but I don't know where that code needs to go:

change following :
<System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Assert, Unrestricted = True)> _

to :
<System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Assert, Unrestricted:=True)> _

Any other suggestions would be great....thanks.
