SYSVOl folder replication issue

Question

Hi,

I'm seeing lot of issue with SYSVol folder replication

ConflictAndDeleted keep filling up after i do an clean up using https://learn.microsoft.com/en-gb/archive/blogs/askds/manually-clearing-the-conflictanddeleted-folder-in-dfsr

What do i need to do to check and fix the issue with SYSVol folder replication

What firewall ports are required for replication because issue is happening between different data centre and all of our DC are firewalled in

Also

Do we need to install DFS Namespace or/And DFS Replication on all our domain controllers

Answer 1

The ports listed here need to be open between sites.

as to broken replication, assuming not yet tomebstoned you could try a non-authoritative sync
