I keep getting Quota violation error in PowerShell when changing Firewall rules-CodePudding

I want to change all Firewall rules to only apply to Public profile, so I tried this:

$rules = Get-NetFirewallRule | select Name

$rules | ForEach-Object {Set-NetFirewallRule -Name $rules -Profile Public}

but i keep getting Quota violation errors like this:

Set-NetFirewallRule : Quota violation 
At line:3 char:26
  ... s | ForEach-Object {Set-NetFirewallRule -Name $rules -Profile Public}
                          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      CategoryInfo          : NotSpecified: (MSFT_NetFirewallRule:root/standardcimv2/MSFT_NetFirewallRule) [Set-NetFirewallRule], CimExcepti 
   on
      FullyQualifiedErrorId : HRESULT 0x8004106c,Set-NetFirewallRule
 
Set-NetFirewallRule : Quota violation 
At line:3 char:26
  ... s | ForEach-Object {Set-NetFirewallRule -Name $rules -Profile Public}

how can I fix this? tried it in PowerShell 5.1 and PowerShell 7.x too.

CodePudding user response：

The issue is, that you currently query all rules and store them in the variable called $rules. Then you loop through those rules but once you set the new rule you do not assign the single element of the variable $rules to the parameter Name, you assign them all. So a working version would be:

Get-NetFirewallRule | ForEach-Object {Set-NetFirewallRule -Name $_.name -Profile Public}

As you said the processing is slow you want to process the items in parallel you may have a look at:
