Knowing that an agent is not reporting is essential, as if the agent is not reporting then the status of all the monitors on the system will not be up to date. As such I have been looking into doing this and have come up with this: $Agents = Invoke-Command -ComputerName $SCOMServer -ScriptBlock { Import-Module

SCOM Alert Retrieval Performance using PowerShell

Test-ActiveSyncConnectivity – 403 Forbidden at ‘Issue an HTTP OPTIONS command’
I have spent some time troubleshooting an alert from SCOM that ActiveSync was not working on all Exchange 2010 servers in an environment. The environment is currently in co-existence with Exchange 2016, with all client access services already pointed to 2016.

Exchange: Checking the CAS and MBX servers used in an EWS Request
Recently I have been working on an issue where EWS requests sent to an Exchange environment were not working with the expected Exchange Version. The environment was in transition so was running both Exchange 2016 and 2010. All mailboxes involved in the request were hosted on 2016 and the CAS services had already been cut

WSUS: Failed to run WSUS Server Cleanup. Error: The DELETE statement conflicted with the REFERENCE constraint

From searching through the database the problem appears to have been caused by a computer changing its Target Computer Group, but not being completely unassigned from the old computer group. Failed to run WSUS Server Cleanup. Error: The DELETE statement

They offer a lot of flexibility and the ability to query a lot more systems that is available natively through SNMP, WMI or other built in monitor types.

WSUS Update Manager – Manage & View Updates for Computer Groups
One of the most annoying flaws in the WSUS MMC snap-in is how the filter for Approval status filters updates on whether they have any approvals rather than whether they are approved for a specific computer group. We found out that due to an automatic approval rule for a test group, a whole group of
