Promotion of this domain controller to a global catalog will be delayed for the following interval. 
 
Interval (minutes):
%1 
 
This delay is necessary so that the required directory partitions can be prepared before the global catalog is advertised. In the registry, you can specify the number of seconds that the directory system agent will wait before promoting the local domain controller to a global catalog. For more information about the Global Catalog Delay Advertisement registry value, see the Resource Kit Distributed Systems Guide.
