How to purge MSMQ system queue journal programaticaly on a workgroup installation ?

Question

I try this : MessageQueue mq = new MessageQueue(".\Journal$"); mq.Purge();

It work good on XP. But, on windows 2003 server, I always have this error : "A workgroup installation computer does not support the operation."

Answer 1

Try using format name like so:

MessageQueue mq = new MessageQueue("DIRECT=OS:computername\SYSTEM$;JOURNAL");
mq.Purge();

I think that system queue can't be access by path. You have to use format name.

look at Yoel Arnon's comment at the bottom of the page.
