I have two F5 221 configured exactly the same with the latest 4.2.15 update yet I keep loosing access to one.
Of them, both on same network, yet one keeps loosing SFC/CIFS service and one has web service in the control panel menu and the other it's absent?

Hi! Which version did you upgrade to TOS 4.2.15 from? If you upgrade across multiple versions, the upgrade may be incomplete. If the WebDAV Server is missing, it is recommended that you reinstall the system.
