WinRM troubleshooting

If WinRM (Windows Remote Management) is not working properly, destination systems will not appear in the pool and load balancing will not work. WinRM is therefore a fundamental requirement for communication with destination systems.

How to restore WinRM connectivity:

1. Open the Local Group Policy Editor​

  1. Log in directly to the affected server. Then open the Local Group Policy Editor by pressing Windows + R, entering gpedit.msc, and confirming with Enter.

  2. Navigate to the WinRM settings:

    Computer Configuration
    └─ Administrative Templates
       └─ Windows Components
          └─ Windows Remote Management (WinRM)
             └─ WinRM Service

  3. Double-click Allow remote server management through WinRM.

    1. Set the policy to "Enabled".
    2. In the "IP address filter" field, enter an asterisk * so that connections are accepted on all IP addresses.
    3. Click OK to save your settings.

 

2. Update Group Policies​

Open the Command Prompt (CMD), enter the following command, and press Enter: gpupdate /force

 

3. Restart the WinRM Service​

Open PowerShell as Administrator, enter the following command, and press Enter: restart-service winrm

Once completed, the WinRM service will again accept connections, destination systems will be correctly displayed in the pool, and load balancing will work as expected.
