Node Manger not reachable

1. start the AdminServer using startScript “startWebLogic.sh/cmd”
Step2) Start the NodeManager.
Step3) Login to admin-console and then see if the NodeManager is Reachable or not at the below console path

4 connect('weblogic','weblogic','t3://localhost:7001')

5 nmEnroll('C:/bea103/user_projects/domains/7001_Domain','C:/bea103/wlserver_10.3/common/nodemanager')
6

7 b)Then again check in the console path if NodeManager is Reachable.
Step4). Once NodeManager is Enrlolled and Reachable in the admin console then continue the following steps.
Step5). Kill the AdminServer because now we need to start it using WLST command nmStart() and NOT using the start scripts.
Step6). Open a command prompt run “setWLSEnv.sh/cmd” and then run the following command

Now if you can see the Admin Server status that means now your AdminServer is now reachable. Hope these steps solves your NodeManager is not reachable
