    I have a great working DFS structure where all links reside on Windows 2003
    R2 machines and a native Windows 2003 infrastructure!

    I basically only run 1 hot site ( the remote location , 11 of them ) and
    then i have one other machine that serves as a "secondary backup if one of
    the primary site's go down ). This is hard coded in the properties of the
    link within the GUI. Basically forcing clients to use the primary one.

    Works great, the backup server is then used to backup the data securely in
    our corporate office! Works great!

    I'm ready to retire the old backup server!
    I'd like to setup a new WINDOWS 2008 r2 64BIT STD server and then install
    DFS and slowly migrate it to being the backup server and remove the links
    from the old one over time.

    Q: Has anyone ran win2k8 64 bit r2 on dfs before? I think r2 is out
    Q: Any issues that you can think of?

    We have a domain based root fyi.

    Bump ? Anyone ran windows 2008 standard SP2 with DFS enabled ?

    Do you mean DFSR (replication) or DFSN (Name Space)?

    Both. Guess I'm not really asking the question right or something.

    I don't want to create a new namspace as I already have one.

    I just want to add this new server into the organization and have it
    participate, thats all. It will just be a windows 2008 sp2 std server and
    not the typical windows 2003 r2 server that all other servers reside on.

    Just trying to put the latest out there!

    I see in windows 2008 dfs under file serverices that you can CONNECT to an
    existing name space and manage it.

    Thats what I'm asking. Looks like I found it. I can't see why I can't make
    this member server part the dfs environment.

    There are two issues. 1) The name space and 2) the replication. I have not used
    W2008 R2 but have W2008 64bit servers.

    It sounds like you have set up the DFS name space with only links and the links
    point to unc shares, similar to me. When I set up the W2008 server first I made
    it a DFS name space server. This copied the name space definition to the W2008
    server DFSRoot but no data is held and the link targets still point to the
    existing server. Next, one at a time, I added new targets on the new server. For
    each I used the wizards help to configure replication for the new link target
    and a soon as possible I disable the referrals to the new target, in theory a
    user could be connected to the new empty copy but I did this out of hours so the
    risk was small. Then I waited for replication to complete, enabled the new
    target and disabled the old target. Last I disabled replication to the old
    target and waited for the event log to confirm replication was removed before
    deleting the old target data.

    All went well.

    Interestingly I had a bit of luck while doing this. The original server suffered
    a disk failure during replication and even though there was raid 5 on the data
    the registry got corrupted. Recovery ended up with the server running but the
    server service had died completely. Much to my surprise I noticed the Network
    was still running flat out. It turned out the DFSR service was happily
    completing the replication of the last two target folders (300GB) from the old
    to the new server. A few hours later and my new server had a full replication
    set of data and I simply switched to the new file server. Phew!

    Thanks Dave for taking the time to share the information. What you did
    sounds exactly like what I had in mind for me! Thanks!

    The nice thing is in my situation 99.99% of the time no user will ever be
    connected to this server. This server(last target) will act as a live backup
    if a branch server goes down(first target). When is say target I mean target
    priority option. You can manually set it to LAST (new win2k8 SP2) or FIRST
    (branch server). So this is how I force them to connect to their branch
    server. A VBS login script maps them to it.

    So I don't want my new server to be a new domain named root server. I hope
    I don't have to switch that! I want to keep the vbs script mapping and
    environment in place.

    It's my understanding that when you create an AD Domain based name space
    that it becomes part of "AD"... That means once you have everything set up (
    replication, links, targets etc any Windows server can manage that info by
    loading the DFS add/in. ( in fact I just tested this and all my links showed
    up but not replication groups. I added all my existing groups so I have two
    management servers!! V- Cool..

    Well wish me luck with this replication action!

    That god you replaced that server in time!

    Everything is working well. I am going to setup replication to begin.

    I wanted to re-iterate, it is two folder targets ( 1 branch ) (1 backend )

    I user OVERRIDE REFERRAL ORDERING on properties of each target to set FIRST
    and LAST .

    The interesting question is what will I set for the new server since it's
    the third!!

    just to let you know, it all worked out fine! I didn't make the win2k8r2
    server a name server because it was not a DC.

    I just added folders and made it a root target and boom replication occured!
    Worked great so far, all my branch server shares are replicated!!!

    Glad to here it went well. Don't be surprised if the off client connect to the
    lower priority link. It happened to me on W2003 R2 in a single site. I never
    worked out exactly why, I assume it was slow response from the high priority
    server and the client decided to use the available alternative. Hence my plan
    now it to disable the alternatives and manually enable them when necessary.

    Yah very happy with it. I don't think I've experienced the fall back issue.
    When I deployed this years and years ago I made sure each XP client had the
    fall back KB patch applied. I even tested this and it worked. If it isn't
    applied the users just keep working off the backup when the primary has been
    repaired. We usually get a call if someone is working off the backup.
    Thanks for the tip! Our branch servers would never be that busy, at most 15
    people connect to it!

    Thanks for sharing. By the way you can run more than one root domain name
    when you apply a patch. Some litature states you need Win2kr3 r2 Enterprise
    to run multiple roots, not true. Apply this patch(forgot) and you can run
    another \\domain\rootname\ "root name"

    Do you have any other tips? I know if your a user and you click on the
    share your accessing then choose properties that you can see what server you
    are running off of. Good for troubleshooting.

    Also do you have each site as a "DC"?

    Q: Has anyone ran win2k8 64 bit r2 on dfs before? I think r2 is out
    R2 is NOT out. SP2 is. R2 is expected RTM on monday (same date as Win7) and then it will be available on MSDN in the days to
    come, however the real release date is probably around oct 22 as Win7 has that date, so it depends on your MSDN membership level.
