Product: Puppet Remediate
Version: All versions

Solution

Puppet Remediate can’t communicate with WinRM servers that have Message Level Encryption (MLE) enabled. MLE is enabled by default in most WinRM configurations. In the following steps, you’ll create a registry key to disable MLE and fix the issue.

Before you complete these steps, ensure that:

• Valid WinRM credentials were added to Remediate.

• WinRM is running on remote nodes.

• You don’t have networking issues.

1. Create the following registry key to enable unencrypted messages, which disables MLE.

    Registry Hive   HKEY_LOCAL_MACHINE
    Registry Path   Software\Policies\Microsoft\Windows\WinRM\Service
    Value Name  AllowUnencryptedTraffic
    Value Type  REG_DWORD
    Enabled Value   1
    Disabled Value  0

2. On the impacted Windows nodes, restart the WinRM service.
