2nd DFS Server Erasing Files

I have a pair of Win2K3R2 servers.  I used RoboCopy with /COPYALL to copy folders from one machine to another and set up appropriate share.  When I start the DFS by adding name space server and target referral folders plus setting up full-mesh replication with the primary server being the first server, the 2nd server deleted some but not all folders!  It's not exactly replicating folders between two machine.  What causes this?  All the time stamp and security settings are the same, copies are exactly the same and it refuses to grab a new copy from first server after deletion.  I'm at loss here, after spending 40 hours trying to get this to mirror each other.

Regards,

John

AshlandSG:

DFS under Windows 2003 R2 doesn't work they way it did in previous versions, and has (for all intents and purposes I see) been rendered useless by Microsoft removing he file locking capabilities. We fought with MS over this exact thing and their solution was, "Buy SharePoint".

It's not a lock problem.  I'm aware of lock problem and have a seperate disk for shared workbooks, quickbooks and stuff that won't work with DFS.  However, my problem is after setting up DFS between two identical hosts, the 2nd host wiped out 50% of the files as "preexisting" and/or "conflicted", and never re-replicated the original file off from the first host.  So, what am I doing wrong, or is DFS broken?  Do I need a different software to mirror servers two-way, such as Double-Take or NeverFail?

I've allowed DFS to do the initial replication multiple times without issue. Set your primary server, and allow it to replicate to a fresh folder on the second server.

Going to give that a try on the 2nd LAN server.  But, boy, we're talking about 3 other WAN servers that are also experiencing similiar issue and that's going to take forever.

The funny thing is that it only removed SOME folders (roughly 50%) and left the rest alone.

OK, I deleted the entire DFS/DFSR, stopped services, removed DFSRoot, removed DFSRPrivate on both servers and restarted service.  Came up clean.  Recreated DFS Namespace, added folder targets and enabled replication.  I told the replication service to replicate one folder containing 63 subfolders on the primary server and the secondary server only replicated 19 of those subfolders before it said it was done!  No further replication was taking place.  This is still the same situation, whether I prepopulate the 2nd server myself or let DFS populate it from scratch.  Why is it not completely replicating all subfolders?  All of the folders have full domain admin privs, including the share.

Yes, this is sure going to be worth 500 points to anyone who could come up with the correct solution.

Apparently, no one has the slightest idea.  However, I seem to have found a solution, though not a fix.

I think the problem may be related to corrupted folders.  When I drag and drop folders (save DfsrPrivate) out of DFS area on the first server, it of course deletes on the 2nd server.  When I dragged them back into DFS area, it populated all except one folder.  I could not drag that folder back in.  It created an empty folder and the folder becomes "locked".  I get an access denied error (and I'm ad Admin) and there's no "security" tab to change anything.  I had to reboot the server in order to get rid of that stuck folder.  I then created a new folder and dragged the content of old folder into the new folder, leaving the old folder out.  Everything replicated fine.

Funny thing is that there were no errors, no access denied, nada at first.  Oh, well, so much for a lucky guess moving folders out and in DFS helped.  I've seen similiar postings elsewhere saying files weren't fully replicating and I suspect the same workaround will solve their problem.

500 points for me. :-)  We can now close this case.
