The required computer object was not found in Active Directory. As a result, the Message Queuing Service started, but in offline mode. This means that applications may access local queues, create private queues or send messages to other machines using the DIRECT format name, but not access any Directory Service functionality, such as creating, locating or creating public queues. This can result from:
1. Message Queuing 1.0/NT4 only: the name of the computer was changed after Message Queuing was installed. In this case, first uninstall Message Queuing and then reinstall it.
2. Active Directory replication latency: some information written on one of the domain controllers by Message Queuing installation has not replicated yet to a local domain controller used by the Message Queuing Service. Another source of change which needs to replicate is when changing the machine's name after Message Queuing was installed. Until replication takes place, Message Queuing will remain in offline mode. Notice that replication delays may be high, depending on your Active Directory configuration. Please contact a domain administrator if this problem persists.
