Background
Earlier I was troubleshooting an application that relies on WinRM.
Based on the error I knew I had network connectivity issue.
Error Message
I do not have the error message captured pictorially.
But, here is a simulation.

Textual
Starting labWebServer01 app pool WebservicesSales... [labWebServer01] Connecting to remote server labWebServer01 failed with the following error message : WinRM cannot complete the operation. Verify that the specified computer name is valid, that the computer is accessible over the network, and that a firewall exception for the WinRM service is enabled and allows access from this computer. By default, the WinRM firewall exception for public profiles limits access to remote computers within the same local subnet. For more information, see the about_Remote_Troubleshooting Help topic. + CategoryInfo : OpenError: (labWebServer01:String) [], PSRemotingTransportException + FullyQualifiedErrorId : WinRMOperationTimeout,PSSessionStateBroken
Troubleshooting
Outline
There are a few ways to troubleshoot network connectivity issues.
For now let us make sure that the destination host has availed WMI and that it is running off his default network port ( 5985 ).
To determine winrm’s listener configuration, we will use “winrm enumerate winrm/config/listener“.
WinRM
WinRM – Enumerate Listener
winrm enumerate winrm/config/listener
Syntax
winrm enumerate winrm/config/listener
Sample
winrm enumerate winrm/config/listener

Explanation
- Address
- Network Bindings
- *
- (*) mean all local host network interfaces
- Network Bindings
- Transport Protocol
- HTTP
- Â Enabled
- True
- URL Prefix
- wsman
- Certificate Thumbprint
