- Their system status needs to be “Green” (healthy) all the time.
- The Windows Firewall must be disabled on all servers.
Everyone strives to have a healthy (all green status indicators) CM12 environment and this is completely possible. However, if Windows Firewall is turned off you will get the following warning message every hour:
SMS_HIERARCHY_MANAGER reports (Message ID=3353): “Hierarchy Monitoring detected that the ConfigMgr SQL Server <fqdn> ports 1433, 4022, are not active on Firewall exception.”
Besides being incredibly annoying, your component status will immediately be placed in a warning state.
How do you solve this problem? You don’t because currently there is no solution.
Since there is no solution, I ended up creating a Connect feedback item to suggest to the SCCM team that they create a registry key in order to turn off this warning message. This registry key would prevent your CM12 site from going into a perpetual warning state. If you have experienced a similar situation, make sure to you vote up this Connect item!
