we have several servers that are dfs replica's for a folder of 20gb
software install files

one of them I want to remove from this replication and then safely
delete all of the files without it replicating back to the other servers
and deleting everyones files .... how do I do this safely?

im testing this first on a small test lan where i deleted the server
replica from dfs yet when i delete or add files into the deleted servers
folder it still replicates back to the other servers ..... what did I
miss?

FRS configuration is done via Active Directory. This means that once
you delete a replica member in Active Directory (presumably by using
dfsgui.msc), you have written to a single DC. Now you must wait for
the following to happen.

1) Your updated configuration must be sent to other DCs (if you have
multiple DCs). The important part is that the DCs from which the
replica member machines read their FRS configuration get the latest
configuration update. It's simplest to just wait for the changes to
replicate through AD. You can use repadmin.exe to speed this along.

2) Once the FRS configuration in AD has replicated, the FRS service
running on the various replica members must see the new configuration.
The FRS service is set up to poll the AD configuration at regular
intervals. I believe the longest interval is once per hour. You can
use the ntfrsutl.exe tool to speed up the polling period and/or
perform a manual poll. Be careful with the switches -- specify them
in the correct order.

Until the above happens, FRS will continue replicating. So if you
delete files too quickly from the member you are removing, FRS will
still think it's part of the replica set and will replicate the
deletes normally. Obviously you didn't want this to happen.

I believe the safest procedure is to do the following.

1) Update the configuration using dfsgui.msc.

2) Wait for AD replication to complete or use repadmin.exe to speed it
along.

3) Once you know all DCs have the new configuration, use ntfrsutl.exe
to initiate a manual AD poll on all machines.

4) Use ntfrsutl.exe and get the "sets" output on the member you are
deleting. Verify it is no longer showing membership in the replica
set that you have removed.

5) [Optional] Drop a test files into the replica set on the member
being removed as well as on other members that will remain live.
Verify you don't see the files show up. Obviously, the test files
should replicate among the remaining servers but the remaining servers
should not see the files from the ones that you are removing. Also
the test files on the remaining servers should not show up on the ones
being removed.

6) Clean up your files on the servers being removed.
