I have a Jenkins server running happily on a Windows server. I need to connect 2 other windows servers as slaves.
One connects in fine (start using JNLP, then installed as a Windows service).
The other fails to connect using JNLP. Whether I use the Launch button or the javaws command line it fails with 'Unexpected Error - Unable to launch Slave Agent for {node}'. If I start the slave using the headless command line it works, so I suspect it's not networking/firewall related.
I'd like to get the JNLP launch working so I can install it as a Windows service.
Other notes:
- the Jenkins URL is set OK
- we're using Matrix security, but anonymous has Slave/Connect
Any help gratefully received.
