DNN module skin container settings are stored in the TabModules table. Use the following SQL statement to reset all containers:

update TabModules set ContainerSrc = NULL

To update spcific modules you could execute something like:

update TabModules set ContainerSrc = '[G]Containers/sL001_DarkRed/No Container.ascx' where ContainerSrc = '[L]Containers/DarkRed/No Container.ascx'

Host containers will start with "[G]" and site containers will start with "[L]"
