Register Websphere as a service

I have installed Websphere 6.1 on Windows but it only registered Dmgr as a service: how can I register nodeagent and the appsrv as well?

Here are the commands to launch:

WASService -add nodeagent -servername nodeagent -profilePath "C:\Program Files\IBM\WebSphere\AppServer\profiles\AppSrv01"

WASService -add server1 -servername server1 -profilePath "C:\Program Files\IBM\WebSphere\AppServer\profiles\AppSrv01"

How to run Win apps as service

Problem: I have a Windows application which has to be always open. Therefore it stays on a server, but I have to be careful and disconnect every time stop working, or the process gets killed.

Solution: http://www.cypressnet.com/Products/autotask/autotask.htm: "This allows for many types of tasks to be ran in the background, even when the users are logged off." Not for free.
