          [JENKINS-36840] Repeating error while connecting to slave machine

          Hi Prathap,

          as far as I know, the Windows agent that is failing to launch here is part of the "core" component.

          Please let me know if you really meant submitting the bug on the slave setup plugin: if not so, I will route to "core" which seems to me a more appropriate place.

          Thanks

          Hello, I just had the same problem with Jenkins ver. 1.651.1 after upgrading windows slave to Java JDK 1.8.1.101,
          I got exactly the same error, then I unstalled and went back to the JDK 1.7.0.76 and jenkis slave startup went back to normal. So why don`t you try installing Java JDK 1.8 at the windows slave, to see if it works.

          Won't be fixed. See JENKINS-67604 for the details of the deprecation of agents started by WMI calls using DCOM.
