Hi @ all,

we have 3 Windows 2003 Sp2 R2 servers, 2 of that are the namespace-server.
All 3 Servers are only member server, not DC.

There are 6 folder targets, and the target referral per target are only
active on 1 of the three servers.

Problem: There are many files & folders, that are moved to the
conflict&delete folder in DfsPrivate-Folder.

In the event log the ID 4412 are logged:

Event Type: Information
Event Source: DFSR
Event Category: None
Event ID: 4412
Date: 05.06.2007
Time: 12:28:55
User: N/A
Computer: server02
Description:
The DFS Replication service detected that a file was changed on multiple
servers. A conflict resolution algorithm was used to determine the winning
file. The losing file was moved to the Conflict and Deleted folder.

Additional Information:
Original File Path: D:\data\xxxxxx\xxxxxxx
New Name in Conflict Folder:

File ID: {657A4CE1-6830-4821-92B0-189BF7561348}-v88878
Replicated Folder Name: DATA
Replicated Folder ID: EBB6D131-6831-4AFC-BBE4-7241AFAA4F77
Replication Group Name: domain.intranet\dfs\data

Member ID: E86CF603-FEC1-42CF-94BD-C80172EA540B


This event are logged on all 3 servers, on the server, who was the referral
server, most often as the other servers.

Past 1 week we installed Service Pack 2 on this servers and a few days ago
the error went away.
Since 1-2 days the failure is coming back.

On the servers we have not running a virus scanning application and i donŽt
know, which service/program are open/change the files, so the dfsr service
thinks, the files are changed on both or 3 servers.
This are only file-server.

The clients are windows XP Sp2, on the same network, but in different
subnetŽs, routet via RoutingSwitch.

Can anyone reconstruct this problem? Or has anyone the same problem and
knows, how to "repair" it?

Thanks for your help

File conflicts (event ID 4412) are not an error condition. The event is an
informational event telling you a file was updated on more than one member
before the changes had time to replicate. Since you have three servers
replicating with DFSR, and all three servers are accessible to users as DFS
targets, it is possible that users themselves are causing this. If one user
changes a file on server A at the same time another user changes it on
server B, DFSR resolves the conflict for you and moves the conflict loser to
ConflictAndDeleted.

In the DFSR debug logs, the USN Consumer (USNC) entries have a Reason: field
that shows what type of change was made to the file. To tell who/what made
the change, you need to enable NTFS auditing on the folders you care about
monitoring.

There are only 1 referral per dfs share active, so the user canŽt change the
files on the other servers.
No Virus scannning software on Servers.
Service Pack2 installed

IŽve opend a PSS call now, i will see, what heppendŽs here.

Thanks for your support

I've seen that in a few cases:

1. A bug - but you put SP2 on and that loophole is closed with the latest
DFSR.EXE service executable.
2. Poorly written anti-virus software - it was scanning the replicated
folders, adding alternate data streams to files and causing conflicts and
reanimations that led to conflicts.

Buuuuut... you cut both of those out nicely. :)

In order to troubleshoot this we will need access to your DFSR debug logs
from all three servers, file system filter driver info, as well as the
conflictanddeletedmanifest.xml data. I suggest opening a case with us here
in PSS for deeper analysis - conflict cases like this are pretty much
one-off's usually if not the above 2 things. If you have a Premier contract
you can open through normal channels. If not, you can open a per-incident
case with our Professional support here:

Hey andre..

m facing the similar issue here we have two server and replication from Primary to other server is not happing. i am getting multiple below events in event viewer

The DFS Replication service detected that a file was changed on multiple servers. A conflict resolution algorithm was used to determine the winning file. The losing file was moved to the Conflict and Deleted folder.

Additional Information:
Original File Path: E:\Data\DDOC1\Data\Opodo\data\r\rrieaaaa.b
New Name in Conflict Folder: rrieaaaa.b-{3FA94DA0-079A-4A7A-88BC-29BF8AD5ECD7}-v2867669 The problem i am suspecting is that be have cleaned out primary folder some time ago and those contents still exist in other server. i belive that is making this issue..

also the other server has Waiting for initial replication error in DFSR logs

any help?
