Configuring Two Way Replication in DFSR on RODC

In my previous post, we saw how can we configure 1-Way Replication in DFSR on RODC... "RODC - The Story of One Way Replication" (http://www.adshotgyan.com/2012/07/rodc-one-way-replication-story.html)

But does that means that we cannot have a 2-Way Replication in DFSR on RODC?

Don't you remember in an earlier post "Configuring One Way Replication in RODC" (http://www.adshotgyan.com/2012/07/configuring-one-way-replication-in-rodc.html) we saw that by default when we configure Replication in DFSR on a RODC, It is always a 2-Way Replication

 So, In this post, We will see how can we configure a 2-Way Replication in DFSR on RODC

My Lab:-

One Writable Domain Controller: MyDC
One Read Only Domain Controller: MyRODC

Replicated Folder: Two Way Data
Replicated Group: Two Way Replication

The Folder "Two Way Data" has been created on the writable domain controller "MyDC"



The same folder "Two Way Data" has also been created on the read only domain controller

Please remember the fact that the folder name need NOT be the same. I have kept the folder name just for ease



Creating the Replication Group



Added the Servers involved in Replication





Path for the folder to be replicated being defined on the writable domain controller "MyDC"



Defining the path of the folder being replicated on the read only server "MyRODC"


The Turning Point: The selection of "Make the Selected Replicated Folder on the Member Read Only". If we want to configure a 2-Way Replication, then do NOT select this check box. But just in case you wants to enable 1-Way Replication, then you need to select this check box

So the key to 1-Way / 2-Way Replication is this Check Box






The Replicated Group is now Created... And its a 2-Way Replication Group....



Let`s create a file in the Replicated Folder on the writable domain controller "MyDC"



And the file has got replicated on to the read only domain controller "MyRODC"


The main test begins now.... Let`s keep our fingers cross

We are now going to take off.... :).... Creating a file on the read only domain controller "MyRODC"....

Remember that earlier when we configured 1-Way Replication and then tried creating a file on the read only domain controller "MyRODC" then it didn't allowed us to do so.. Gave us an error "You do not have Permissions"

Wow.... This time we were able to create a file on the read only domain controller


And the file got replicated as well... :)
