 Should you need to remediate just one policy definition and not the entire policy initiative, you can run the remediation script targeted at the policy reference id that can be found under [Policy Initiatives](../../Policy-Initiatives). For example, to remediate the **_Deploy AMBA Notification Assets_** policy, run the following command:
 
 ```powershell
 #Run the following command to initiate remediation of a single policy definition
-.\patterns\alz\scripts\Start-AMBARemediation.ps1 -managementGroupName $pseudoRootManagementGroup -policyName ALZ_AlertProcessing_Rule
+.\patterns\alz\scripts\Start-AMBA-ALZ-Remediation.ps1 -azureEnvironment "AzureCloud" -managementGroupName $pseudoRootManagementGroup -policyName ALZ_AlertProcessing_Rule
 ```
