DFS-R with an DFS-N path

    hi,

    i would like to know if the following would work.

    I would like to setup a 2 node fileservercluster (clusterservices) with
    DFS-N (that should work :) ).

    I also would like to setup a 2 node NLB cluster.
    both nodes in the nlb cluster will be DCs.

    On this NLB cluster I would like to use DFS-R with FRS.
    One source for the FRS should be the unc path of the filecluster.

    is this possible?
    or is there a better way to do somthing like this.

    the goal is to never have to change names for shares again even if there is
    another cluster added running clusterservices.

    i hope this was still understandable ...

    I would like to know more about what you think you are accomplishing by
    enabling NLB on Domain Controllers.

    well,

    i have 4 physical server and 1 san.
    at the moment thes are used all separately in a mixed structure of
    windows and novell.
    i the future I want the sestem completely on windows server 2003.

    i would like to use 2 server to share the san for clusterservices.
    this way i have a redundant file- and printserver.

    i would like the 2 remaining server to host dns and dhcp services.
    using nlb i will only habe one ip to access both and there will be no
    interruptions in the event of an error on on of the machines.

    i would make them both domain controllers to have more then one copy of
    the active directory database.

    we habe another san that connects via scsi to just one server. I would
    like to use this a my second frs target in te DFS-R. Since this second
    san sits in another part of the building, it will server as a backup from
    where i can make the "real" backup to the tapes then.

    basically it's all about redundancies and high availability.

    but since i have not started jet, I'm open to better sugestions.

    the system might grow in the future. so with DFS-R I would like to make
    sure, that I will not habe to change scrips and mappings in the future.

  4. There's no need to use NLB to make DNS and DHCP and AD highly available
    services. Simply make both servers DCs running AD-integrated DNS and use
    DHCP split-scopes. With multiple DCs, each automatically has a writable
    copy of the AD Database (until you get into RODCs with Server 2008 and
    read-only copies that don't participate in replication - but that's a
    different story. :-> )

    Cluster your 2 remaining servers (remember, you need W2K3 Enterprise or
    Datacenter) for your File and Print solution.

    thank you ryan,

    i just read some more articles about the subject and I think I'm really
    getting there.

    what i still can't find is an answer to the dfs question.
    on the fileserver i would like to use dfs-n.
    but since i can not use fsr with dfs-n i would like to use dfs-r with the
    ad where one path is pointing to an dfs-n root of the fileserver.

    i'm not sure if this is still understandable.
    maybe there is a much more elegant way to solve this.

  6. Sure, it can host a server root name space. Why would you want to do that,
    though? If you need redundancy in the namespace, make it a domain name space
    and it will be redundant in that each DC hosts the namespace.

    Chuck and I discussed this several times, and I summarized all of this here:
    http://msmvps.com/blogs/clusterhelp/archive/2006/10/10/DFS-and-Clustering.aspx
    Why in the world would you want to do that? The NLB IP address will not be
    registered in DNS with the DC SRV records, so it would kind of defeat the
    whole purpose, plus, DCs don't need NLB for redundancy or load balancing as
    DNS provides location information for multiple DCs for clients to access as
    needed.
    Nope, you can't do this. Again, see the above link re: DFS and clustering.

  7. You can do this, but be aware that you will not receive full support for
    your configuration if it is not purchased as a complete solution from the
    Windows Server Catalog.
    You can provide redundancy for these services just by deploying them on
    multiple servers. Read this for more info:
