Unenlisting an MSMQ send port in batch file

I’ve got a solution which I setup / cleanup using batch files …

There are a pair of MSMQ ports, send and receive, with another application on the end of the queues

I’m finding I can’t properly stop the orchestration in the batch file … the error is the send port is unenlisted

 – I’m using the StopOrch.vbs script from the SDK samples

But I can go into BizTalk Admin Console and manually stop the orchestration with Full Terminate Ok

The setup / cleanup works Ok if I don’t actually push any messages down the MSMQ queues
