Hi,
Thank you for your post.
According to your description, I understand that the error message regarding the Forefront Client Security State Assessment Service (10006) shows in the system event log.
As far as I know, the FCS SAS service is used for the Security State Assessment(SSA). The client will use the mom agent to get the policy regarding SSA from the FCS server and upload the result to the FCS server. We only can get the state assessment result from the FCS server.
So in this scenario, the Forefront Client Security(FCS) has been installed to the client with the parameter “nomon”, we could safely ignore the error message regarding the FCS SAS. Additionally, you may disable the FCS SAS service on the client.
