Attempt to query specific performance counters on the delivery controller from PowerShell fails.

Queries:

Get-Counter -Counter "\Processor(_Total)\% Processor Time"
Get-Counter -Counter "\Memory\Available MBytes"
Get-Counter -Counter "\PhysicalDisk(_Total)\Disk Transfers/sec"
Get-Counter -Counter "\PhysicalDisk(_Total)\Avg. Disk sec/Transfer"
 
Get-CimInstance -Query "SELECT TotalPhysicalMemory FROM Win32_ComputerSystem"
Get-CimInstance -Query "SELECT LastBootUpTime FROM Win32_OperatingSystem"

Results:

Get-Counter : Internal performance counter API call failed. Error: c0000bc4.
Get-Counter : The specified object was not found on the computer.

Performance Monitor shows a warning during the attempt to add any of the counters:
