I'm trying to grab the Distributed Cache service using PowerShell so I can change the managed account that runs it. This cannot be changed through the CA UI.

I am not able to get the service using any of the following PowerShell commands (they return a null object).

$farm is set using $farm = get-spfarm

$farm.services | where ($_.TypeName -eq "Distributed Cache")

$farm.services | where ($_.Id -eq "<The GUID of the distributed cache service>")

$farm.services | where ($_.TypeName -match "Distributed"

$farm.services | where ($_.TypeName -like "*Distributed*")

I am running PowerShell as a local administrator and as the farm administrator. Again, all of these lines return a null object. AFAIK any of these should get me the cache service. I can see it listed when I just enter $farm.services but somehow the pipe-filtering (?) is not working properly.

I'm not able to get any of the other services using this method.

Try this one, the service called App fabric.

$farm = Get-SPFarm
$cacheService = $farm.Services | where {$_.Name -eq "AppFabricCachingService"}
$accnt = Get-SPManagedAccount -Identity domain_name\user_name
$cacheService.ProcessIdentity.CurrentIdentityType = "SpecificUser"
$cacheService.ProcessIdentity.ManagedAccount = $accnt
$cacheService.ProcessIdentity.Update() 
$cacheService.ProcessIdentity.Deploy()
