+### <a name="iphelper"></a>Scenario: You receive the error "Unable to find an entry point named 'GetPerAdapterInfo' in DLL 'iplpapi.dll'" when executing a runbook.
+
+#### Issue
+
+When executing a runbook you receive the following exception:
+
+```error
+Unable to find an entry point named 'GetPerAdapterInfo' in DLL 'iplpapi.dll'
+```
+
+#### Cause
+
+This error is most likely caused by an incorrectly configured [Run As Account](../manage-runas-account.md).
+
+#### Resolution
+
+Make sure your [Run As Account](../manage-runas-account.md) is properly configured. Once it is configured correctly, ensure you have the proper code in your runbook to authenticate with Azure. The following example shows a snippet of code to authenticate to Azure in a runbook using a Run As Account.

+```powershell
+$connection = Get-AutomationConnection -Name AzureRunAsConnection
+Connect-AzureRmAccount -ServicePrincipal -Tenant $connection.TenantID `
+-ApplicationID $connection.ApplicationID -CertificateThumbprint $connection.CertificateThumbprint
