Trigger.bat - Which Server?

[adam_mc]

We have a multi-server install standalone Content Manager Server (011), Application/Standby Content Manager Server (012) , and a standalone Application Server (013).

For reasons that are quite complicated, I need to run the trigger.bat on the standalone Application Server (013).
However, when I run this, I am getting what appear to be login/authentication errors.
I am able to run the same trigger.bat on the (012) server.

What am I missing?
Any thoughts would be most appreciated.

Thanks in advance,
Adam.
