This health service is attempting to send data from or about health service 9d13fabf-1bba-1e4f-3bb8-6af174d370bd but is not authorized to do so. The data has been discarded. This may indicate an attack on this health service, or it may be a result of configuration not being in sync across management servers. Because this event may occur frequently, it will be suppressed for the next 5 minutes. Help us to resolve this issue. Regards Donald Dsouza

Do you receive this on a lot of clients or only this one? Did you check whether the computer where the agent is installed is approved? This normally indicates that the installation of the agent was not succesfull or in the case of a manual install it was not approved. If you need more assistance please shout...It's doing common things uncommonly well that brings succes.
