Lost permanent mapped network drives.

Sometimes, the remote machine is not available at the moment of the system boot and the user do not understand the message that alert them to “Make the connection available next time…”, so they click on “No” and specific applications may not work properly. Is there any way to prevent this alarm to come out, or any way to make the “Yes” choice automatic? I noticed that the system deletes the corresponding “persistent” connection from the Registry and probably this can be forbidden somehow.
