DCOM errors in event log on SAM server

Updated July 27th, 2016


This article provides brief information and steps to resolve the following error:

DCOM was unable to communicate with the computer <ip address>  ***.**.*.***. using any of the configured protocols. Filling up the System event log errors on the Solarwinds application server. 


SAM v6.2


This can be due to a WMI component in an application template being deployed against a Linux node. Alternatively
on Windows nodes, the poller may be unable to poll due to insufficient access/High physical memory, etc… on the remote node. The actual error is caused by the remote node not being able to respond to WMI-get requests.


  1. Go to Edit Nodes for the node that is in the error message in the event log using the IP. 
    • If the node is registered as a server name you may need to look up the name to search for using the ip address in a ping command. 
  2. On the node look for applications that are grey or have a status of known. click into the application and then click edit application. Look at the components that show unknown and are WMI components. If these are deployed on a Linux then remove from the assigned node.  
    • This can be done by going to settings -> SAM Settings -> manage applications finding the application template and clicking on the check box for the application -> clicking delete.
