How to fix "The WS-Management client received too many results from the server."

Description

This error occurs when a Windows Remote Management (WinRM) or PowerShell Remoting command requests data from a remote server, and the size or volume of the returned data exceeds the configured data limits on the client machine. To prevent denial-of-service (DoS) attacks and excessive memory consumption, WinRM enforces strict quotas on data transfer. When a query (such as fetching large event logs, active directory objects, or massive file lists) breaches these limits, the client abruptly terminates the connection and throws this error.

Step-by-Step Fixes

You can resolve this issue by increasing the maximum envelope size or the maximum characters per packet on the client computer, the remote server, or both.

Method 1: Increase WinRM MaxEnvelopeSize Using PowerShell

This is the most common fix. It raises the total size limit of the data packet that the client can receive.

1. Click the Start menu on your local Windows machine.
2. Type PowerShell.
3. Right-click Windows PowerShell and select Run as administrator.
4. Type the following command to check your current maximum envelope size (default is usually 500 KB):

   Get-WSManInstance -ResourceURI winrm/config | Select-Object MaxEnvelopeSizekb

5. Run this command to increase the size limit to 8192 KB (8 MB):

   Set-WSManInstance -ResourceURI winrm/config -ValueSet @{MaxEnvelopeSizekb = "8192"}

6. Run the same command on the remote server if you still encounter issues after modifying the client.

Method 2: Adjust MaxProviderResponses via WSMan Provider

If the server is sending too many individual XML elements or objects, you need to adjust the provider response limits.

1. Open Windows PowerShell as an administrator.
2. Run this command to view your current WSMan client configuration:

   Get-Item WSMan:\localhost\Client\*

3. Increase the response limits by executing:

   Set-Item WSMan:\localhost\Client\MaxEnvelopeSizekb -Value 8192

4. Restart the WinRM service to apply changes immediately:

   Restart-Service winrm

Method 3: Modify the Group Policy (Alternative for Enterprise Environments)

If you manage multiple computers, you can deploy this fix across your network using the Local Group Policy Editor.

1. Press the Windows Key + R on your keyboard to open the Run dialog box.
2. Type gpedit.msc and press Enter.
3. Navigate to the following path in the left sidebar:
   • Computer Configuration > Administrative Templates > Windows Components > Windows Remote Management (WinRM) > WinRM Client
4. Look for the policy named Specify maximum envelope size in KB in the right pane.
5. Double-click it, select Enabled, and set the value to 8192.
6. Click Apply and then click OK.
7. Open Command Prompt as an administrator and run gpupdate /force to apply the policy.

Method 4: Filter Your Queries (Best Practice)

If changing system configurations is not ideal, modify your script or command to request fewer results at once.

• Use pagination parameters if available.
• Filter data on the server side using parameters like -FilterBy or -FilterServerSide instead of downloading everything and filtering locally with Where-Object.
• Limit results using clauses like -First 100 or Select-Object -First 100 to test if smaller batches succeed.
