Hello,
I would like get another Jenkins server, first server work as properly for me. On second I encountered follow problem:
I've try install Windows Service from Jenkins Slave Agent running on slave machine. Unfortunately, I can't see 'File' option in menu while jnlp agent is opened.
Used latest 1.617 version.
What is problem here? Did you heard about it? How can I work normally?

Meanwhile, I have tried cumbersome work around (that finally works for me) by editing jenkins-slave.xml and directly copy jenkins-slave.exe to c:\jenkins directory and then run from cmd follow command:
sc.exe create "Jenkins Slave" start= auto binPath="c:\jenkins\jenkins-slave.exe" DisplayName="jenkinsslave-c__jenkins"

Thanks,
Sasha
