DFS replication question (FRS, not newer DFSR)

    Question

  • We have a DFS namespace called ADMgmt that we have on our Domain Controllers (we use it to hold our AD scripts and some other stuff).  Our writeable DCs are namespace servers in DFS.  So the DFS looks like this:

    Namespaces -> \\DC01\ADMgmt, \\DC01\ADMgmt, \\DC03\ADMgmt

    The ADMgmt share on each DC replicates to the others, and here is where I am confused.  There are no replication groups for the entire domain.  In DFS, if I click on "Add Replication Groups to Display..." and then search the domain, nothing shows up.  But replication is most definitely working. 

    I know that SYSVOL has some information for replication partners in ADSIEdit, so I thought I would check there.  Sure enough there is a listing for the ADMgmt share in ADSIEdit, under Default naming context -> DC=<domain>,DC=com -> CN=System -> CN=File Replication Service -> CN=DFS Volumes -> CN=ADMgmt.  There are 3 folders, one for each writeable DC (so DC01, DC02, DC03), showing the objectGUID for the DC.   In each folder, there is a nTDSConnection object for each of the other DCs.  So DC01 folder has a nTDSConnection object for DC02 and DC03.  This all makes sense as far as what is happening.

    My question is:  how did this information get in ADSIEdit if DFS says there are no replication groups in the entire domain?  Were these ADSIEdit entries added manually by my predecessor?  I took over this environment about a year ago, and this is the first time I am adding a new DC to the environment, so need to have the ADMgmt folder replicate to the new server. 

    Any help would be appreciated.

  • Hi,

    Domain based namespace will be stored in AD. As you mentioned ADMgmt is replicated to new server before, which means the replication created in the past.

    You could have a test to create the replication again if it is fine to sync ADMgmt folder to all DCs --- check if there is any error occurs when creating the replication gorup, and if the values stored in AD will be deleted once you delete the replication group.

    I figured that it must have been an old replication group.  So I created a new DFSR group and deleted the old one in ADSIEdit.  All the replication is working fine.  Thanks for the additional information.
