Each instance of MSMQ should have its own unique Queue Manager ID. If multiple machines have the same Queue Manager ID, destination queues think messages are actually coming from the same computer, and messages are lost/dropped. If you clone new servers from a template or from old servers, you'll get duplicate Queue Manager IDs. This function causes MSMQ to reset its Queue Manager ID. .EXAMPLE Reset-MsmqQueueManagerId .LINK http://blogs.msdn.com/b/johnbreakwell/archive/2007/02/06/msmq-prefers-to-be-unique.aspx #> [CmdletBinding()] param( ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -Session $ExecutionContext.SessionState Write-Verbose "Resetting MSMQ Queue Manager ID."
