I was recently cleaning up a lot of old computer accounts in Active Directory, when I encountered the following message on a some of them:
To dig into this a bit further, I went to View->Users, Contacts, Groups and Computers as containers from the Active Directory Users and Groups MMC. With this view, I expanded the computer in question and saw that a MSMQ (Microsoft Message Queuing) object was inside the computer which made it a container.
To be honest, I was unaware that enabling MSMQ would make these types of changes within Active Directory, but it really did not matter as I was deleting them anyway. These were XP computers, so I don’t know if that still occurs with Windows 7/8 systems or not. It is not a service that is really used by user computers, so I don’t know why these few machines had it installed/configured.
If anyone has ideas or comments on this item, please post a comment and we can all learn a bit more.
