Hi Ami857,

You doing follow step.

A) To reset the Console administrator password on a Microsoft Windows system, do the following:

Check which account the 'gstd' service is running as (Log On As), usually this is the Local System account and therefore we need to set the variable within the System Environment variables rather than from the command line. If its running via another user then we should login as that user and set from the command line as described below.

1. For Local System Account, create a variable called GST_RESET_PW with a value of 1 in: -  Go to Computer Management > Properties >Advanced. Create the variable under System variables (bottom window) or select the appropriate user from the top window for User variables.
2. From the command line logged in as the user who runs the service, enter the following:
        set GST_RESET_PW=1
3. Go to Start > Settings > Control Panel > Administrative Tools > Services.
4. Stop and restart the GST service. At this point, the password resets.
   Note: For NetWorker Management Console 3.2, this change requires a reboot.
5. Log on to the Console server as administrator, with the default password 'administrator'.
   The password can now be set to a secure password once again. (For details, see " Managing NetWorker Console server users" in Admin Guide.)

6. Delete or unset the variable created in step 1 -  Go to Computer Management > Properties > Advanced. Delete the variable under System variables (bottom window) or from appropriate user from the top window for User variables.From the command line, set the environment variable to null by entering the following command without giving the variable a value:
         set GST_RESET_PW= (blank)
   (press [Enter], without giving a value)

7. Go to Start > Settings > Control Panel > Administrative Tools > Services.
8. Stop and restart the GST service.
   Note: For NetWorker Management Console 3.2, this change requires a reboot.
9. Log in as administrator using the secure password.
