SharePoint 2013: This Distributed Cache host may cause cache reliability problems

Problem

You added a new web front end server to the farm.  Subsequently, you see the following report in the farm's All Reports listing:

Title	This Distributed Cache host may cause cache reliability problems.
Severity	2 - Warning
Category	Configuration
Explanation	This Distributed Cache service on this Distributed Cache host has been stopped but not unregistered from the farm. In order to avoid reliability issues, it is recommended that a Distributed Cache host with a stopped Distributed Cache service be unregistered from the farm
Remedy	Unregistered cache hosts using PowerShell. For more information about this rule, see http://go.microsoft.com/fwlink/?LinkID=3136960".
Failing Servers	[new WFE]
Failing Services	SPTimerService (SPTimerV4)
Rule Settings	View

 
Solution

1. Ensure ShellAdmin Access
1. Login to the WFE using the SharePoint Setup User Administrator account (eg, spAdmin).
2. On the WFE, launch an elevated SharePoint Management Shell.
3. Execute the following command:

   Get-SPShellAdmin

   This checks the farm configuration database for those users who can modify it.
4. Verify that the SharePoint Setup User Administrator account has been added.  If it isn't, make it so.
2. Get Service Instance ID
1. Login to the WFE using the SharePoint Setup User Administrator account (eg, spAdmin).
2. On the WFE, launch an elevated SharePoint Management Shell.
3. Execute the following command:

   Get-SPServiceInstance | Where-Object {$_.Server -Like "*<yourWFE>*"} | Select-Object TypeName, ID, Status | Sort-Object TypeName

   This generates a listing of SharePoint-related service instances on the machine, including their IDs and statuses, sorted.
4. Look for Distributed Cache in this listing.
5. Copy its ID.
3. Delete Service Instance
1. In the same management shell, execute the following command:

   (Get-SPServiceInstance <yourWFE-ID>).delete()

   If you now re-execute the command in step 2.3, above, you will no longer see it listed.  However, if you should now re-analyze the rule, it still remains. And if you check the server services control panel, you will see that the AppFabric Caching Service status remains Running.  
4. Remove Service Instance
1. In the same management shell, execute the following command:

   Remove-SPDistributedCacheServiceInstance

5. Re-analyze Rule Violation Problem
1. In Central Administration, navigate to the Review problems and solutions page.
2. Click on the item, This Distributed Cache host may cause cache reliability problems.
3. Click the Re-analyze button.

Notes

• I tried the process in the Microsoft TechNet article cited above (2); however, this failed to resolve the problem.
• You could of course stop the AppFabric Caching Service service using the server Services panel, but this is not recommended. I've tried this myself without success.  I then used the PowerShell command, above, and this worked.
