Discovery Credential Issue

Appreciate some assistance from someone more knowledgeable than myself. 

The ECC queue input payload for some workstations shows credential issues when trying to classify.  SEE BELOW

WMI:classify probe shows.  (Authentication failure with the local MID server service credential.</error><error>Failed to access target system.  Please check credentials and firewall settings on the target system to ensure accessibility: The RPC server is unavailable. but differ depending on the probe used).  I have found that this could be Windows firewall blocking this service.   Is this assumption correct?

HTTP Classy Probe shows:  (error="No credential found for type [BASIC_AUTH]" probe_time="0" result_code="41).  This is an error I'm not familiar with?

 

Learning how to troubleshoot discovery.  Mine is a mess.

 

Thanks

Are you able to get any other sort of data via discovery?

Many organizations will not allow a random computer on the network (in this case, your MID Server host) to access other hosts and get WMI information.

Most commonly, to fix the above, you'll need to:

  1. Get a windows network account on the domain, typically a "service account"
  2. Have the windows/domain administrators grant that account the rights to access the machines you are trying to discover via SNMP/WMI/any other protocols you need to use
  3. Log in to your machine running the MID Server and set it to run the MID Server process *as* the windows network account from step 1. Details on how to do that are here: https://docs.servicenow.com/bundle/london-servicenow-platform/page/product/mid-server/task/t_ConfigM...

It could be a windows firewall..but there is also the most likely opportunity that you dont have correct credentials. Take a look at the troubleshooting section of my best practice document, that and lots of videos Are available to help compliment your discovery training.

Thanks all for the assist.  Discovery seems to be a beast and I've got my work cut out.
