Some of the users have resources open for name, closing these open resources may result in loss of data. Are you sure you want to close all open resources?
When you choose to disconnect a user from a shared resource, you risk causing the user to lose unsaved data. Consequently, any time that you choose to remotely disconnect a user, Server Manager presents you with a confirmation message.
If you are sure that you want to disconnect the user, choose Yes. If not, choose No, and before selecting this option again, alert the user of the imminent disconnect.
