Error in SCOM log

Question

I am having issues with my MS servers. This is in the log: I can't seem to find any blog about it. OpsMgr Management Configuration Service failed to communicate with System Center Management Service due to the following exception System.Runtime.Remoting.RemotingException: Failed to connect to an IPC Port: Access is denied. Server stack trace: at System.Runtime.Remoting.Channels.Ipc.IpcPort.Connect(String portName, Boolean secure, TokenImpersonationLevel impersonationLevel, Int32 timeout) at System.Runtime.Remoting.Channels.Ipc.ConnectionCache.GetConnection(String portName, Boolean secure, TokenImpersonationLevel level, Int32 timeout) at System.Runtime.Remoting.Channels.Ipc.IpcClientTransportSink.ProcessMessage(IMessage msg, ITransportHeaders requestHeaders, Stream requestStream, ITransportHeaders& responseHeaders, Stream& responseStream) at System.Runtime.Remoting.Channels.BinaryClientFormatterSink.SyncProcessMessage(IMessage msg) Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) at Microsoft.EnterpriseManagement.Mom.Internal.IRootConnectorForConfigService.OnStateSyncResponse(String filename, Guid target, Boolean isManagementServer) at Microsoft.EnterpriseManagement.ManagementConfiguration.Communication.AgentCommunicationProvider.SendConfigurationFile(Guid targetAgentId, Int32 priority, String fileName) at Microsoft.EnterpriseManagement.ManagementConfiguration.Communication.AgentCommunicationProvider.SendConfiguration(Guid targetAgentId, Int32 priority, Stream agentConfiguration) at Microsoft.EnterpriseManagement.ManagementConfiguration.Engine.TracingAgentCommunicationProvider.SendConfiguration(Guid targetAgentId, Int32 priority, Stream agentConfiguration) at Microsoft.EnterpriseManagement.ManagementConfiguration.Engine.AgentRequestProcessor.<>c__DisplayClassa.<ProcessConfigurationRequest>b__6() at Microsoft.EnterpriseManagement.ManagementConfiguration.Engine.HealthServiceLoggingCommunication.CallHealthService(HealthServiceCall healthServiceCall)

Answer 1

1. Restart System Center Data Access Service and system Center Management Configuration Services
2. make sure that System Center Management Configuration service account are assigned to the Sdk_user role in the operational database. The account used for the SDK and Config Service account should be granted local administrative rights on all management servers in the management group.
