Windows farm | jenkins slave configuration via "Launch agent via execution of command on the master"

[LnT]

Hello -

Looking for help - w.r.t jenkins slave configuration via "Launch agent via execution of command on the master"
As I'm looking to minimize the memory consumption in remote slave machine via Availability "Take this agent online when in demand and offline when idle"

Jenkins master is Windows 2008 Server
jenkins slave is Windows 2008 Server

Installed psexec in Jenkins master (ref : https://docs.microsoft.com/en-us/sysinternals/downloads/psexec)

Please find below log of lauching the slave agent. Agent is not getting connected.

just before slave test_node gets launched ...
executing pre-launch scripts ...
[01/31/19 14:06:52] Launching agent
$ C:\PSTools\psexec \\RemoteServer -u jenkinsUser -p Password cmd /C "java -jar C:\slave\agent.jar"
