How can I find out what the DFS server is using for replication?

Pre Windows 2003 R2 servers can only use FRS for replicating files...

Windows 2003 R2 server and higher operating systems can use FRS (if windows 2003 R2) or the DFS replication service to replicate files.

What operating system do you have?

win 2003 r2 sorry

Look at the Services...

Is the File Replication Service running?

Is the DFS Replication service running?

(the running service will tell you what replication service your server is using...)

However, it could be using both..  This is because in order to provide backwards compatibility and a migration plan, both service are included in Windows 2003 R2  (note: DFS Replication service will only be there is the DFS components have been added using ADD/REmove Programs - windows components -- DFS)

Anyway, another way to tell it to look at the DFS management tools...

You may have two tools...

1) Distributed File System

and/or

2) DFS Management

Both are running.

I thought FRS would be running for replication of sysvol?

DFS Management for r2 right?
I have it open but do not see how it lets me know the replication service.
This all came about of an argument when someone told me I did not know what I was talking about when I was asked if DFS was using FRS and I said Nooo FRS is a seperate service. Am I wrong.  I understand it could have been configured that way but I do not think it is and I need to prove it.

Thanks for your help.

YES! see that is just it, I deleted the shortcut to the old version Distributed File System because I use the DFS Management and the DFS service for replication, It was not in the Administrative tools either.
I have seven groups in the DFS Management replication.

Thanks
