1. Current versions of Adagio modules will check the workstation setup when starting and will give you a message if Opportunistic Locking has been turned back on. (Some Windows updates in the past have reset it.)

2. You can run CHKSYS anytime.

3. On the server, you might want to run CHKSYS after any update. If automatic updates are turned on for the server, perhaps check after Micrsoft's "patch Tuesdays."
