Hello Dochelp,

In paragraph " DATA_EXTENSION_RETRY_TIMEOUT" we have information about FirstTryTime and Count related to REMOTE_CO command, but it seems that it's not explained how the client should use this information nor when the server should increase the Count attribute.

In paragraph " NTFRS Replica Set Object" msFRS-Topology-Pref: 
Attribute not used by FRS. It seems that it's as when you create a replication of a DFS replica this attribute is set and changing the value in the interface has changed the value stored in the AD database.
Does this mean that what ever the topology is set to the replication scheme is always the same ? If so can you clarify it or point me to the place of the documentation where it's specified ? Is it the same for FRS replication of DFS replica and for SYSVOL ?

The documentation didn't explain very well or I didn't understand how to find the parent of a replicated object, after my investigation it seems that the objectGUID of replicated object is the same on all the replica and a downstream partner use this information when it needs to compare 2 files/folders for modifications or when it needs to find where to store/change/delete a file or folder.
It seems also that for the sysvol replica, it's the GUID of the NTDS object that is used as GUID of the frsRootPath.
Can you confirm or precise the correct information about this ?
