Go to Jenkins server, select the node you have defined for this Windows instance. It will give you the command you need to run, on the command line.
Test that that works on the command line, then figure our how to get procron to do that for you. The command will look something like this (use google for other examples): "java -jar agent.jar -jnlpUrl http://ip-of-jenkins-server:port-of-jenkins-server/computer/name-of-node/slave-agent.jnlp -secret long-unique-number" -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
