Viewing Replication Entries
1. On one or both of your servers, start Active Directory Sites and Services, expand
Sites, then Default-First-Site-Name (note that this is the default name of the site
created when you installed Active Directory), Servers and then each server in turn.
2. You should see and NTDS Settings entry under each server. Select each in turn and
look at the entry in the right-hand window. In each case you should see an
automatically generated entry from the other server. These are the automatically
generated connections for replication.
3. When you are setting up Active Directory for real, you should check these entries —
sometimes Active Directory will appear to have installed successfully, but replication
may be broken. Checking for these entries is a good way to check that replication is
4. Start the Active Directory Replication Monitor program on one of the domain
controllers (Windows 2000 Support Tools.)
5. Add one of your servers as a monitored server (Edit menu or right-click.) You can add
the second as well if you like. It’s possible to save the monitored server list for ease of
6. Under each server entry you’ll see entries for each naming context. Expand each in
turn and click on the entry for the replication partner beneath one of the naming
contexts. You should see a status message in the right-hand window, hopefully
showing that the last replication was successful. The replication monitor gives you
more information about replication since you can see the status of replication of each
naming context (domain, configuration and schema.)
7. Select one of the servers and right-click and look at the options available. Select
Properties and click on the Inbound Replication Connections tab. This gives you more
information on the replication connections.
Triggering Replication Manually
8. On one of your servers, in Active Directory Users and Computers, create a user or
Organizational Unit (or both.) Immediately on the second computer, check in Active
Directory Users and Computers to see whether these objects exist.
9. Now in Active Directory Sites and Services, expand Sites, then Default-First-Site-
Name, then Servers, then the other server (i.e. the one where you did not create the
user or OU), then NTDS Settings and select the connection entry in the right-hand
windows. Right-click and select Replicate Now. This triggers replication from the
server whose name appears in the “From Server” column of the entry, to the server to
which the connection belongs.
10. Check again on the second computer to see whether the objects you created have
11. Note that the replication was only triggered manually in one direction. If you want to
initiate two-way replication you must initiate the Replicate Now command on both of
the replication entries under NTDS Settings of each server.
12. On one of your servers, create a user. Trigger manual replication to replicate it to the
13. On both servers at the same time, edit the user’s properties, and change different
attributes on each server. For example, on one you could change the Office
description, and on the other, the telephone number.
14. Initiate replication manually in both directions.
15. Examine the properties of the user on both servers and note the result.
