The name of the computer that contains the queue, without the two preceding backslashes (\\).
The computer identifier could not be retrieved, possibly because the directory service is not available; for example, if you are working offline.

You can use a computer's identifier for two purposes, among others: to read the computer journal and to set security certificates. However, you cannot call for a remote computer when you are working offline because the application must have access to the directory service on the domain controller.
The computer identifier (or machine identifier) is a Guid that Message Queuing creates when a computer is added to the enterprise. Message Queuing combines the computer identifier with the Machine and Journal keywords to create the machine journal's format name, which has the syntax Machine=<computeridentifier>;Journal. The machine journal, which is also known as the journal queue, is a system queue that stores copies of application-generated messages when the UseJournalQueue property is true.
This syntax for the journal is only valid when constructing the format name for the queue. The path name syntax is MachineName\Journal$.
