I have a question about intersite AD replication.
I have a multi-site domain (single domain, 2003 domain/forest level) with sites in the UK, Australia, USA and Germany.
The schedule of the IP site link between the UK and Australia sites is set to constant and the replication interval is set to 90 minutes. Both sites are using the correct site links.
I was under the impression that this means any changes made in the UK would be replicated every 90 minutes, so if a user was created in the UK, for example, it could be up to 90 minutes before it shows up in Australia.
However, I've just been troubleshooting a user creation issue and whilst using replmon I can see that replication occurs for the domain partition every 15 minutes between sites. This was reflected in the speed it took for a user created in Australia to appear in the UK without any manual intervention.
This not really a problem but a question as I was expecting to see replication every 90 minutes as configured in the replication interval.
Can someone explain why this is?
More info upon request!
