glassfish4 - cluster node username

I have a cluster running on Windows 2008 with 2 nodes: 1 CONFIG and 1 DCOM. The DCOM node is working and validate-dcom is successful. However, even though I have the username set to apps_admin in the dcom node configuration, I see that the instance started on the node is not run under that user. Looking at the user.name system property I see $.

This is only the case when I run start-instance from the DAS. When i start the instance as a windows services on the local machine, the user.name is correct (same as the user configured in the windows service run-as).

So my question is: How can I configure what Windows user runs the instances on remote DCOM nodes when starting the node with asadmin commands (instead of as a local windows service)?
