I have 9.3 running on my Windows Server. The command to start the service is below. I think you would hvae to try and create another ...SASServer2\wrapper.conf directory and files. You might try copying what you have under SASServer2\.. and then point the exe to the new directory structure.
D:\jboss-5.1.0.GA\service\wrapper.exe -s D:\jboss-5.1.0.GA\server\SASServer1\wrapper.conf
Just a thought.
