SYMPTOMS

If Microsoft Message Queuing cannot resolve the name of the MQIS (Message Queue Information Store) or domain controller, it fails when it tries to open public queues. Message Queuing cannot initialize in offline mode (and cannot open local public queues) if it cannot resolve the name of the MQIS or domain controller server.

CAUSE

Each Message Queuing client keeps a list of MQIS servers in the registry (either Microsoft Windows NT 4.0 primary event collectors [PECs], primary site controllers [PSCs], backup site controllers [BSCs], or Windows 2000 domain controllers). When one of the servers in the list is not responding, Message Queuing jumps to the next server. However, if the IP address of the server cannot be resolved, Message Queuing quits and stops the name resolution process.
