When you have identified what Frondoor service has stopped working you will need to remote desktop to the windows server where that Frondoor service is running.

Once you are on the server you can open Internet Information Services (IIS) Manager and open the sites tab on the left to find any running Frontdoor Services.

If there are multiple Frontdoor services running and you are unsure which one needs to be restarting then you can do the following to find the name of the Frontdoor service that displayed in NRDAv2 UI.

1. Right click on one of the services and click Explore. (This will open file explorer to the location of the service)
2. There should be a file called appsettings.json, open this file with a file editor e.g. Notepad
3. Once the file is open it will display a json object and the key variable you are looking for is "ServiceName"
4. The value of the "ServiceName" is the same name that appeared in the NRDAv2 UI. e.g. "ServiceName": "FrontDoor-DFSData"

2. Navigating to Hangfire Web Address

HangfireWebAddress HangfireWebAddress

When you have identified the Frontdoor service in IIS you will need to open a web browser to that service providing the port and adding "/hangfire" to the end of the URL e.g. "http://localhost:4040/hangfire"

A quick way to navigate to the address through IIS is to click the "Browse Website" button on the right hand

side of the screen under the Manage Website Tab.

After the web page has opened you can update the URL by adding "/hangfire" to load the page.

When the page has loaded you should see a Hangfire Dashboard. If this page has loaded successfully then the Frontdoor Service will start processing files again.
