I'm confused about our windows AD replication. It's at Windows 2003 forest and domain functional level. The documentation seems to indicate that if I make a change in AD it will be replicated very quickly throughout the DCs in the same site. AD sites and services shows automatically generated connection objects with a schedule set to 1/hr for the intra-site DCs to and from eachother. If I create a new user, delete a group, or change a password how long should it take for the changes to propagate?
