Please raise the DCOM Autnetication Level

Post by rudi.lotze »

Good Day Everyone,

Since the recent spade of microsoft Updates we have started receiving these alerts in Nagios.
Nothing i've tried online yet seems to work - Including the registry recommendation from MS or DCOM permission changes.

CRITICAL - [Triggered by _ItemCount>100] - 1279 event(s) of Severity Level: "Error,Warning", were recorded in the last 1 hours from the system Event Log. (List is on next line. Fields shown are - Logfile:TimeGenerated:EventId:EventCode:SeverityLevel:Type:SourceName:Message)
System:20211014100454.651102-000:10036:10036:Error:Microsoft-Windows-DistributedCOM:The server-side authentication level policy does not allow the user from address x.x.x.x to activate DCOM server. Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application.

Has anyone got a similar issue and found a fix?
regards,
