Active Directory agents cause CPU utilization to spike to 100% on monitored 2012/2012 R2 DCs when using WinRM (4275148)

Active Directory agents using WinRM connection to Windows 2012/2012 R2 Domain Controllers cause CPU utilization to spike to 100% on monitored servers.

This issue does not happen if  DCOM is used instead of WinRM

Workaround:

(Recommended)  Create a Domain Local Group in an OU in the AD domain as per MSDN discussion thread.

-OR-

Increase MaxEnvelope size setting of WinRM by running below command on monitored DC, as documented under Troubleshooting section of Active Directory cartridge Release Notes:

winrm set winrm/config @{MaxEnvelopeSizekb="1000"}

Then restart Widows Remote Management service

-OR-

Modify REG key permissions on monitored DCs as documented under System Requirements section of Active Directory cartridge Release Notes and then configure Active Directory agent to use DCOM instead of WinRM.
