The Symantec Management Agent is not running as the Local System Account.
By default, the Symantec Management Agent runs under the local system account. If the agent service has been modified to use an alternate logon credentials, then you may run into this error. It is best to leave the Symantec Management Agent service running as Local System Account.
After making the change to the Logon Credentials, stop and start the agent.
