Configuring proxy settings for the On-premises Data Gateway

Change the Windows service account for the On-premises Data Gateway service.
The default account for this service is NT SERVICE\PBIEgwService. You will want to change this to a domain user account within your Active Directory domain. Or, you will want to use a managed service account to avoid having to change the password.
You will want to change the account on the Log On tab within the properties of the Windows service.
Restart the On-premises Data Gateway service.
From an admin command prompt, issue the following commands.
```
net stop PBIEgwService

net start PBIEgwService
```
Start the On-premises Data Gateway configurator. You can select the windows start button and search for On-premises Data Gateway.
Sign in to Power BI.
Restore the gateway using your recovery key.
This will allow the new service account to be able to decrypt stored credentials for data sources.
