WCF MSMQ Service unable to detect that a queue is transactional

Question

I have created an service oriented application using wcf and msmq. We can only use server 2003, so the version of msmq is 3.0.

The service works, but when using the Microsoft Service Trace Viewer. I keep getting warning when opening service hosts about wcf not being able to confirm wether the queue is transactional.

Here is the Trace :-

I have done tests using system.messaging to see if the queue is transactional which informs it is, however the tests won't accept the direct format 'DIRECT=OS:server01\poisonqueue' but rather the format 'server01\poisonqueue'.

Could this also be a red herring because I'm using msmq 3.0 ?

Thanks in advance for help.
