To create a new ICB:
Go to Hosts → Manage ICBs on the menu.
Click the Create new ICB button.
Enter a name for the ICB in the Edit initial configuration block view.
Optionally, for each view, select the host group to which the hosts with this ICB should be assigned to when they connect to the Management Server.
By default, the ICB is valid for one day (24 hours). To extend the validity period, click the Change button. Select a new expiration date from the calendar and click OK.
The Management Server will deny host registration attempts that use an expired ICB.
Click Save when finished.
