SqlDataSource Error - Access to the ADO.net Managed Provider 'SqlClientFactory' was denied in the da

[gigi.lagria]

I am getting the following error only on pages that contain a
SqlDateSource (all other pages pull data fine).

Access to the ADO.net Managed Provider 'SqlClientFactory' was denied in
the data source with ID 'SqlDataSource1' because of security settings.

On my local machine - everything works fine. But when i try to run
files on live machine, that is when i get the above error on pages that
contain a SqlDataSource.

Any help would be greatly appreciated in solving this bug!

Thanks!
