Automating DCOM permissions

Hi,

I am trying to automate the building od student machines for the classroom

using GHOST. So far, everything is working well, however I need to set the

DCOM security settings on each machine individually. I have a batch file that

is running to do various things after the ghost build, so I need to know how

to add this in to the mix.

I have a couple of components that I need to add a user in to the "Launch

and Activation Permissions" on the "Security" tab as well as altering the

username / password on the "Identity" tab.

How do I do this from a batch file / command line?

Many thanks,

Paul
