Understanding DFSR debug logging (Part 11: Directory created on Windows Server 2003 R2)

  • Artikkeli

In this scenario we will see a folder added and how that change is replicated between servers. This is useful to understand in order to troubleshoot issues where problems within the USN journal, the DFSR JET database, and the network (including RPC) are preventing replication from working correctly.

 

(addedfolderupstream - Dfsr00006 - 2003.log and addedfolderdownstream - Dfsr00007 - 2003.log)

 

These are two Windows Server 2003 servers called 2003MEM01 and 2003MEM02 in the contoso.com domain. The logs are from 2003MEM01 where the folder is created (upstream) and from 2003MEM02 where it the creation is replicated (downstream). Both servers are participating in the TESTRG2 replication group for the TESTRF2 replicated folder. The folder was called “subfolder”.
