When you expand Enterprise and select Managed Computers in the navigation pane, Patch Manager displays the computers managed by the application. These computers include WSUS servers, SCCM servers, and managed clients in your corporate enterprise. Computers with connectivity issues display connectivity failure or warning status icons in the Name column for systems with WMI connectivity issues.

You can view details about each selected system by clicking the Computer Details tab at the bottom of the center pane. This tab displays the WMI connectivity issues for your selected system.

Use the Computer Details tab to troubleshoot WMI connectivity status issues for a selected system.

In some cases, the Last statuses (such as Last DNS resolution attempt) can report Success while Patch Manager returns a connection error in the Computer Details tab. In these cases, troubleshoot the specific data source or object cited in the error message or modify your Inventory task to exclude the target data source.

  1. Log in to Patch Manager as an administrator.
  2. In the navigation pane, expand Enterprise and select Managed Computers.

  3. In the center pane, select a computer.
  4. In the center pane, click the Details tab.
  5. Review the following connection attempts:
    • Last DNS resolution attempt
    • Last ARP resolution attempt
    • Last Endpoint Mapper connection attempt
    • Last File and Printer Sharing connection attempt
    • Last WMI connect attempt
  6. Troubleshoot any Failed statuses using the table below. 

The following table lists the statuses related to WMI connectivity.

Identifier Description
Last DNS resolution attempt

Reports the status for resolving the computer name Patch Manager obtained from the computer container defined in the Inventory task. If Patch Manager can resolve the name, it stores the IP address in the computer record and displays a Success status. If Patch Manager cannot resolve the name, the application displays a Failed status.  

If Patch Manager cannot resolve the computer name of a remote system, check the network DNS records and the local hosts file (if applicable).

Last ARP resolution attempt

Reports the status for resolving the IP address Patch Manager obtained from DNS. If Patch Manager can resolve the IP address, it stores the MAC address in the computer record and displays a Success status. If Patch Manager cannot resolve the IP address, the application displays a Failed status. 

If a remote system is on the other side of a network boundary (such as a router or gateway), the boundary device responds to an ARP resolution attempt with its own MAC address. In these cases, Patch Manager identifies the MAC address as coming from a boundary device and returns a Failed status. This is normal for systems in remote networks and is not necessarily indicative of WMI connection failure.

Last Endpoint Mapper connection attempt

Reports the status for connecting to the RPC Endpoint Mapper on port 135 of the remote system. If Patch Manager can connect to the RPC Endpoint Mapper, the application displays a Success status. If Patch Manager cannot connect, the application displays a Failed status. 

If the status is Failed and DNS resolution was successful, verify that the firewall is not blocking traffic to the remote system on port 135.

Last File and Printer Sharing connect attempt

Reports the status for establishing a file sharing session on port 445 using Server Message Block (SMB) over IP. If Patch Manager can establish the file sharing session, it returns a Success status. If Patch Manager cannot establish the session, the application displays a Failed status. 

If the status is Failed, ensure that the File and Print Sharing  service is enabled on the remote system. If there are intermediate firewalls between the Patch Manager server and the remote system, ensure the intermediate firewalls are not blocking traffic to the remote system on port 445.

Last WMI connect attempt

Reports the status of the attempt to establish the WMI session. If Patch Manager can establish the WMI session, it returns a Success status. If Patch Manager cannot establish the session, it returns a Failed status. 

If the status is Failed and the previous statuses are Success, ensure that the credentials defined in the credential ring for the remote system are correct. The account used to establish the WMI session must have local Administrator permissions on the remote system.
