I’ve recently encountered an error while I was using the Test-DSCConfiguration cmdlet:
The WS-Management service cannot process the request. The computed response packet size (519056) exceeds the maximum envelope size that is allowed (512000).
The Get-DscConfigurationStatus -All worked well and indicated that I had more than 400 resources in my config.
To fix it, I…
Set-WSManInstance -ValueSet @{MaxEnvelopeSizekb = "1000"} -ResourceURI winrm/config
dir WSMan:\localhost
…doubled the default value of 500KB and the Test-DSCConfiguration cmdlet worked back again as expected 🙂
