Hello Again,
Just looked it up. To do an automatic subscribe you can go to the following menu options : Go to Options > Events > Subscribe to Wbem Events. Now you can select All Servers and click next. At the next screen you can Schedule this job to run every x time, lets say every week or day. This helps when new servers are added, they will auto subscribe to events.
You can also select a bunch of servers, then click on Configure > Configure or Repair Agents, click next and deselect all options exept the first two. Now you will create subscription and test if it works. At the next screen you need to select use sign-in credentials or Use the following credentials for all systems. You only need to use the second if you have no sign-in credentials setup for you servers. These credentials will not be saved and udes for the future. So that depends on your configuration.
Kind regards,
Andrew
