Message Queuing now supports two directory services: MSMQ Information Store (MQIS) and Active Directory Domain Services (AD DS). AD DS replaced MQIS with the release of MSMQ 2.0, allowing Message Queuing to be fully integrated with Windows 2000. Using AD DS as the directory service allows your Message Queuing enterprise to automatically access information about computers in all the Windows 2000 domains in the applicable forest.
To access AD DS, you must have MSMQ 2.0 running on at least one domain controller, referred to as the as the MSMQ DS server, in each Windows 2000 domain. When operating in an MSMQ 2.0 enterprise, the boundaries of the Message Queuing enterprise are now the boundaries of the Windows 2000 forest.
If you do not want to install MSMQ on a machine that is part of a domain, or if your domain does not use AD DS, you can also deploy MSMQ in workgroup mode. However, workgroup mode does not provide public queues, only private ones, and it does not provide message routing or built-in security (that is, encryption and authentication).
