Reboot Admin Server after changes in myrealm

Hi,

Recently I made a few changes in the IP address of the machine which hosts the Active Directory.

Active Directory is configured as a security provider in weblogic, which is set to required in our environment and is on top in the order of authentication providers.

Now after making the changes in the config.xml file, I want to reboot my server but WLS does not let me do so when I tried stopping the server using ./stopWeblogic.sh.

Following is the error:

Connecting to t3://localhost:7001 with userid weblogic ...

Please suggest how do I restart my server!

Thank you.
