remote procedure call canceled|Active Directory not replicate directory partition.I'm installing new AD domain in remote site, the bandwidth latency is 1000 ms, I've done many similar installations like this with the same bandwidth, yet this time I'm getting the following error:

Active Directory could not replicate the directory partition - "The remote procedure call was canceled"
I'm using Windows Server 2003 SP2

Is the NTDS\Parameters\RPC Replication Timeout" increase of a benefit in my situation now or do you have any other suggestion.

Answer:This sounds like an MTU problem over VPN. It breaks RPC.The solution is to fix the mtu on the routers,You saw the article comes from ActiveDirectorySEO http://gnaw0725.blogbus.com/c1404552/

According to my research, this issue may occur if you are trying to replicate Active Directory changes that cannot be replicated in five minutes or less. I therefore would recommend that you refer to the following MS KB article to edit the registry on your Windows Server 2003-based computer to increase the value of the RPC timeout for Active Directory replication.

If this problem persists, please help to generate a Directory Services Edition (Mpsrpt_dirsvc.exe) of MPS report from both DCs. For detailed instructions, please refer to the following MS KB article:

As well as we know, AD Replication is a pull behavior between two domain controllers. On each domain controller, a replication connection is created for this pull behavior to pull data from another domain controller. If the replication connection fails, then AD Replication will not work in one direction.
