The Computer Details tab on the Enterprise > Managed Computers view is particularly helpful when diagnosing WMI connectivity issues with remote systems. Computers with connectivity issues appear in the top pane of this view with either a red circle or yellow triangle over the computer icon in the Name column. Use the details in the lower pane to troubleshoot the issues.

To view WMI connectivity details for a remote system:

  1. In the left pane of the Patch Manager console, expand Enterprise, and then select Managed Computers.
  2. In the upper-center pane, select a computer.
  3. In the lower-center pane, note the statuses for the following connection attempts:
  1. Troubleshoot any Failed statuses as described in the following sections.

Note: In some cases, all of these statuses can report as Success while Patch Manager returns a connection error at the bottom of this view. In these cases, troubleshoot the specific data source or object cited in the error message, or modify your Inventory task to exclude that data source.

Last DNS resolution attempt

Reports the status of the attempt to resolve 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 the status here is Success. If Patch Manager cannot resolve the name, the status here is Failed.

Troubleshooting: If Patch Manager cannot resolve the computer name of a remote system, check the network's DNS records and/or the local hosts file.

Last ARP resolution attempt

Reports the status of the attempt to resolve 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 the status here is Success. If Patch Manager cannot resolve the IP address, the status here is Failed.

Note: 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 status of Failed. 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 of the attempt to connect to the RPC Endpoint Mapper on port 135 on the remote system. If Patch Manager can connect to the RPC Endpoint Mapper, the status here is Success. If Patch Manager cannot connect, the status here is Failed.

Troubleshooting: If the status here is Failed and DNS resolution was successful, ensure a firewall is not blocking traffic to the remote system on port 135.

Last File and Printer Sharing connect attempt

Reports the status of the attempt to establish a file sharing session on port 445 using SMB over IP. If Patch Manager can establish the file sharing session, the status here is Success. If Patch Manager cannot establish the session, the status here is Failed.

Troubleshooting: If the status here is Failed, ensure the File and Printer 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, the status here is Success. If Patch Manager cannot establish the session, the status here is Failed.

Troubleshooting: If the status here is Failed and the previous statuses are Success, ensure 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.
