Hi I want to display all the message with these properties -EventID "FAIL" -Source "AGENT" -SourceContext "Agent". I tried this get-messagetrackinglog -EventID "FAIL" -Source "AGENT" -SourceContext "Agent" -Start "3/20/2011 9:26:00 AM" -End "4/20/2011 9:36:00 AM" This is not working! Thanks for your helps DS

Something like: get-messagetrackinglog -EventID "FAIL" -Start "3/20/2011 9:26:00 AM" -End "4/20/2011 9:36:00 AM" | where-object {$_.Source -eq "AGENT"} You really dont need to filter on SourceContext, its extra info.
