As per my only previous post on making MQSeries work in a multiple-LU environment, here is what I discovered. There's a little trick to making MQSeries for NT work using Microsoft SNA Server 4, where you are have configured multiple LUs.

First, define the MCA User that your channel (sender) is going to run under, by specifying the MCAUSER() parameter in your definition. I used the MUSR_MQADMIN local account.

Next, create a 'configured user' in SNA Server Manager, for this Local Account (MUSR_MQADMIN).

Lastly, open the properties of this 'configured user', and set the default Local and Remote LUs to the LU pair that you want MQSeries to use for this channel.

For multiple channels, you'll have to create a local account for each channel, and ensure each MCA runs under a seperate local account - then assign that account to the specific LU pair in SNA Server Manager.

I hope this tip helps save someone the time it took me to discover this trick.
