Configuration Manager 2012 Console in Read Only
After recently implementing a Configuration Manager 2012 proof of concept environment, my console was displayed in read-only.
It turns out that when installing a primary site under a CAS site you will get the following message until the replication has completed.
Your Configuration Manager console is in read-only mode while this site completes tasks related to maintenance mode
In the Monitoring workspace you can check the Database Replication to see if this is completed and then restart your console. Or you can check in rcmctrl.log. You are looking in either case for “Link is active” to be displayed then you are good to go.
