We recently had an issue raised by a customer that since they had installed the SCOM Agent on the Domain Controllers, they were all reporting the below error.
Alert: Group policy processing aborted – cannot connect to the Directory Service

This one was a nice simple fix, they had installed the SCOM Agent manually and forgot to installed oomads.msi, soon as they installed that the above error went away!
