I recently upgraded our SMP environment to version 7.5. The maintenance windows are still configured in the notification server console, but on the client there are no maintenance windows listed. I'm wondering if I forgot an update plug-in or if there is something else that needs to be configured for the upgrade to allow the maintenance windows to pass through again.
As long as the maintenance windows have a target and is enabled, then the relevant clients should receive them.
If you create a new one do the clients get it?
I just found out from Symantec that their is a bug in version 7.5 with any maintenance windows that is created using week 4. They are working to fix this, so in the meantime, I changed all my maintenance windows to use week 3 or last week.
