Facing issues while applying of OMS configurations with 201-oms-extension-windows-vm template

[Deployment of a Windows VM with OMS Extension](https://github.com/Azure/azure-quickstart-templates/tree/master/201-oms-extension-windows-vm)

### Issue Details

I am trying to deploy 201-oms-extension-windows-vm template from https://github.com/Azure/azure-quickstart-templates/tree/master/201-oms-extension-windows-vm url.

I keep getting the below error:
{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-debug for usage details.","details":[{"code":"Conflict","message":"{\r\n \"status\": \"Failed\",\r\n \"error\": {\r\n \"code\": \"ResourceDeploymentFailure\",\r\n \"message\": \"The resource operation completed with terminal provisioning state 'Failed'.\",\r\n \"details\": [\r\n {\r\n \"code\": \"VMExtensionProvisioningError\",\r\n \"message\": \"VM has reported a failure when processing extension 'Microsoft.EnterpriseCloud.Monitoring'. Error message: \\\"Failed to apply configuration to Microsoft Monitoring Agent.\\\".\"\r\n }\r\n ]\r\n }\r\n}"}]}

I am able to log into the VM and then install the mobility services agent and configure it without any issues.


Is this something with the configurations or with the template. Is this a common scenario. We have already looked at https://aka.ms/arm-debug for debug/troubleshooting info but couldn't find anything useful. What are the common areas we can look for to perform troubleshooting of this template?

Start with the 201-oms-extension-windows-vm template linked in the issue and review the reported Microsoft.EnterpriseCloud.Monitoring extension failure alongside the ARM debug guidance. Reproduce the deployment and inspect its deployment operations and configuration values; done means identifying the cause and documenting or applying a confirmed fix for the failed OMS configuration.
