This is what I took out of your question, please correct me if I'm wrong.

1. You have a daemon process running on an NT system.
2. You have a script that needs to run under a user account, not the system account.

If that is the case, I would look into seeing about Turning a Perl Program into an NT Service. By doing this, you can set your perl daemon to be started up automatically as an NT service and it will be running in the background for whoever logs into that machine. Then your client script can be run under the user account.
