MSMQ Glossary: I

independent client

A Message Queuing computer that runs the Message Queuing service, hosts queues, sends and receives messages, and can operate while disconnected from the network by default. These clients do not require synchronous access to a Message Queuing server to send and receive messages.

internal certificate

A certificate provided by Message Queuing that is used to verify message integrity and the sender's identity when operating in a Windows® 2000 or Windows Server 2003 domain environment.

An internal certificate contains a public key. A registered internal certificate also contains the sender identifier (SID) of the user who registered it. It is written in the form of an X.509 certificate. It does not contain additional sender information that can be used for authentication.

See also external certificate.

internal transaction

A transaction called where Message Queuing is the only resource manager. Message Queuing internal transactions cannot be passed to another resource manager, unlike MS DTC external transactions. Significant overhead is needed to coordinate between several resource managers, thus, whenever possible, Message Queuing internal transactions are a better choice than MS DTC external transactions.
