We currently have a couple of servers in different locations with Windows 2012 R2 Standard installed and all are set up the same. As an example (File server = F1,2,3 etc)
F1 is located in Gothenburg, F2 Stockholm, F3 Northern Europe. All three have a connection of at least 100mbit up / down
F1 and F2 work perfectly and sync / replicate almost instantly when data is written in both directions.
In contrast, the sync / replicate between F1 / F2 to F3 does not work at all. What is written on F3 is perfectly synced to F1 and F2, but the data written on F1 and F2 does not appear at all on F3 and if you check resource monitor for what data is written on F3 then DFS is about 1000 b / second ie it takes years and days to sync / replicate the amount of data we have.
What can this be due to as all of the servers a replicated in settings?
