Delete all MSMQ queues at some PC with PowerShell

We have a small issue at one of our production servers. Once something generated ~10K queues with Guid-like names. Since then they were not deleted as there was a problem: standard MSMQ manager doesn't allow deleting several queues at once.

What to do? Powershell, of course! :) Here goes the script:


[Reflection.Assembly]::LoadWithPartialName("System.Messaging")

[System.Messaging.MessageQueue]::GetPrivateQueuesByMachine("someserver") | % {".\" + $_.QueueName} | % {[System.Messaging.MessageQueue]::Delete($_); }


You may also filter them by name if you do not need to remove them all as I need:


[System.Messaging.MessageQueue]::GetPrivateQueuesByMachine("someserver") | % {".\" + $_.QueueName} | ? {$_ -match "SOME_REGEX_FILTER"} | % {[System.Messaging.MessageQueue]::Delete($_); }

And SOME_REGEX_FILTER is... Yeap, some regex filter :) The -match operator allow us using regular expressions in the Where-Object (alias "?") clause.

Have fun with PowerShell!
