Hey...ok so i have dfs running in 2008 domain...one namespace and 3 target servers...
Servers called A-B-C...Users use Server A,when that goes down they go to B and when that goes down they go to C...So as a test i shutdown Server A....Complaints of users....

1) when they switch over to Server B...some files where lost or outdated...i am assuming some files didnt get replicated from A to B fast enough...or at all....
2) connection times where real slow...so connecting to the namespace was very slow...like 1-2 minutes...

does anyone have any clue as to why this would happen and how to fix??

Cliff GaliherCommented:
Sounds like expected behavior to me. DFS is designed to provide a server-agnostic view of the file system through namespaces and solve some remote office pain points with replication. What you describe is more of a disaster recovery scenario, which was not the intended use for DFS. The feature set isn't really designed or meant for rapid failover. Windows has a completely unrelated feature set for those scenarios, and to really solve what you want, you'd be better served setting up a file server cluster.

You need to first verfify the health of DFS by runing  Diagnostic Report for DFS Replication
http://technet.microsoft.com/en-us/library/cc754227.aspx and check this parameters as well listed in the link:http://networkadminkb.com/KB/a279/dfs-r-health-check.aspx

Checked the DFS event log for any errors and warming and post the same.

For slow replication see this:
Top 10 Common Causes of Slow Replication with DFSR:http://blogs.technet.com/b/askds/archive/2007/10/05/top-10-common-causes-of-slow-replication-with-dfsr.aspx

Configure Staging if not configured correctly.http://social.technet.microsoft.com/Forums/windowsserver/en-US/4c7d8022-9f26-4e54-9c5a-c101ecc68e78/dfs-replication-slow-in-one-direction-opposite-works-fine

Hope this helps
