Overview

When utilizing WinRM to run a script or get a specific performance counter from Windows, a misleading error occurs showing that the XML is invalid. 

The WS-Management Protocol defines the MaxEnvelopeSize value to indicate that the client expects a response to be no larger than the given number of octets, as specified per environment.


Error number: -2144108477 0x80338043

Cause

This is caused by the default size of MaxEnvelopeSizeKB in Windows is less than the required amount of the PowerShell script or the data you try to parse from Windows.

 
 
 
 
 
 
 

Resolution

1. Get the current MaxEnvelopeKBSize in windows and run one of the below commands as admin in Powershell:

winrm get winrm/config
  or 
Get-Item -Path WSMan:\localhost\MaxEnvelopeSizeKb

You will see something like this:
  
Config
    MaxEnvelopeSizekb = 500
    MaxTimeoutms = 60000
    MaxBatchItems = 32000
    MaxProviderRequests = 4294967295
    Client
etc............................................................
2. There are 2 ways to change the MaxEnvelopeSizekb:

    a) Using Powershell:  Set-WSManInstance -ResourceURI winrm/config -ValueSet @{MaxEnvelopeSizekb = "<desiredvalue>"} 
cfg                 : http://<microsoft.schema>/wbem/wsman/1/config
lang                : en-US
MaxEnvelopeSizekb   : xxxxxx
MaxTimeoutms        : 60000
MaxBatchItems       : 32000
MaxProviderRequests : 4294967295
Client              : Client
Service             : Service
Winrs               : Winrs


    b) Using RegEdit:

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WSMAN\Client
Double click "maxEnvelopeSize" in the right pane, choose "Decimal", and change the value to the desired amount
