Windows Server: DFS Replication monitoring and troubleshooting

http://www.hardforum.com/showthread.php?p=1033831473#post1033831473


Seems like there were multiple horrible-nesses occurring.

However, for the sake of future reference here’s what I did:
1) DFS issues may be related to NTDS/Active Directory replication between the DCs that the DFS members are getting their DFS configs from. Checked NTDS replication by forcing a replication through AD sites and services… reviewed via replmon or repadmin /showreps

2) used WBEMTEST to connect to the \\[DFS Member server]\root\MicrosoftDFS namespace (tests DNS entries (maybe WINS too), RDC connectivity, TCP, etc)

3) Ran WMIDiag.vbs which revealed no critical errors

I could not find any errors.

I then restarted the DFS Replication service on the member reporting the WMI errors, and it took a long time.

After restarting, I started getting hits on the following counters on both servers:
dfs replicated folders{DFS replicated folder GUID}\total files received
dfs replication connections{DFS connection GUID}\bytes received per second

[here’s a great article on dfs: http://blogs.technet.com/askds/archive/2007/10/05/top-10-common-causes-of-slow-replication-with-dfsr.aspx]

However, I still have a single replicated folder not receiving updates (monitored via dfs replicated folders{DFS replicated folder GUID}\total files received). I think I need to further investigate how to monitor staging, etc to see what the hell is going on.

Any suggestions are appreciated!
