Active Directory Replication Problems!!

Hello,

I am having a problem with inter-site replication.  Intra-site replication is working just fine.  I have inter-site links setup between our remote locations and our central location.  (Our network is pretty much a star topology when you look at our WAN circuits).

I also changed inter-site replication on those links to 15 minutes, yet replication does not occur.  I have checked the Directory Services event viewer on all of the servers, and none of them have any errors related to replication.  One issue I did find, as this is a recently setup Active Directory environment, I had not had sites and services setup properly initially, as all servers were performing intra-site replication, and computers were connecting to domain servers across different wan links.  I "fixed" this by adding all of our subnets and pointing them to the respective sites.  However, I still receive netlogon errors in the directory services event log saying that x number of workstations are connecting to this server as they have NO_CLIENT_SITE defined for their subnet, yet I do have those subnets created correctly.

Any help is greatly appreciated as this is extremely urgent!!

P.S.  Manually selecting Replicate Now works.. but I want automatic replication to work.

Do you have site links setup between your hub and your remote sites?

What does repadmin /showreps or /showrepl show you on one of the remote sites?

Thanks

Are you running repadmin on a 2008 server? Try to run the command promot with elevated permissions by right clicking and selecting run as administrator.

Did you check the netlogon.log file to verify the Clients IP address, and also verify you have the correct subnets in S&S and no typos.

Just to piggy back Ken's comment take a look at Tony's entry here   http://www.open-a-socket.com/index.php/2009/02/04/windows-server-2008-user-account-control-gotcha-3/

So are you saying if you never initiate replication that replication will never occur? For example if you ran that same command now does it still show

thanks

I am unsure as why it was not replicating all day, but it did begin replicating on its own again, every 15 minutes.  Also, the errors have disappeared about the netlogon client sites.  I am unsure as to what happened??
