After System Center Operations Manager (SCOM) Update Rollup, Agents are not shown under Agent Requires Update
When you install an SCOM Update Rollup you might run into the situation that the agents are not shown under Pending Management – Agent Requires Update.
If there are no agents waiting, you might already have installed the new agents using Windows Update. If not you probably did not install the Rollup with a user account that has change permission on the SCOM DB. When you do the SCOM Server Rollup Update always make sure that you are login into the SCOM server with an user account that has that right on the SCOM DB. If you forgot this when you installed the Rollup Update, just run the update again, and the agents should appear under Agent Requires Update.
