Unfortunately, other Microsoft Exchange services -- including the information store -- depend on the Exchange System Attendant. This means that, if you restart it, you disconnect users from their mailboxes.
Microsoft advises that, after you restart the Exchange System Attendant, you should regenerate virtual directories within 15 minutes. If they're not recreated within 15 minutes, you will have to reboot the server.
I think it's better to just go ahead and reboot the server, regardless, and know for sure that the virtual directories will be regenerated, rather than risk interrupted service for your users twice.
