Understanding DFSR debug logging (Part 10: File Conflicted between two Windows Server 2008)

  • Article

In this scenario we will see a file that has been changed on two servers in between replication convergence and how that conflict resolution is replicated between servers. This is useful to understand in order to troubleshoot issues (or perception of issues that are actually expected behavior) leading to conflicts.

 

(conflictwinner - Dfsr00001 - 2008.log and conflictloser - Dfsr00001 - 2008.log)

 

These are two Windows Server 2008 servers called 2008x86FSRV10 and 2008x86SRV11 in the contoso.com domain. The logs are from 2008x86FSRV10 (where the conflict is won) and from 2008x86SRV11 (where the conflict is lost). Both servers are participating in the TESTRG3 replication group for the TESTRF3 replicated folder. The file was called “confile.rtf”.
