The Maintenance mode scheduler tool written by Tim McFadden has been updated to version 4.

Here are the new features:

• Multi-select Computers  This has been the most requested feature as end users often want to schedule multiple computers at a time without having to create groups.

• Multi-select Computers in Integrated dashboard  Now you can select multiple computers in the dashboards without getting an error

• New Search in Computers and Groups  Now instead of scrolling up in down the list you can just start to type in the name of the group or computer and results will be filtered.

• One Click MM now accepts parameters   Some environments One Click MM was not working as the client security was high or there were DNS issues.  Now you can just add the computer as a parameter.

• New Configuration backup tool for easier upgrades  Now you can back your configuration and upgrade to the latest version of SCOM 2012 Maintenance Mode Scheduler with have to reconfigure all of your settings.
