    Hi All
    Active/Passive Ex2k3 with Win2k3 SP1.
    Due to certain file changes, SP1 needs to be reapplied, due to address books
    not functioning correctly, and Public Folders not being seen.

    the Reapply of SP1 works on my Bridge Head Server, and the public folders
    can be accessed now.

    However, looking at this document:;en-us;174799 Talks about
    installing a SP. Doesnt mention the "reapply" of a SP in a cluster.

    Also, if you look at the bottom, specifically for Win2003 Clusters, it
    mentions that "MS DTC service must be started. If a clustered MSDTC resource
    has not been created in a cluster, the MS DTC service cannot be started. In
    this case, the installation of Windows Server 2003 SP1 on the cluster node
    will fail"

    So im confused :-( Can I just PAUSE the inactive Node, reapply the SP1 again
    to update the files, reboot and then fail EVERYTHING over? Or does MS-DTC
    have to be moved onto the NODE that is being updated first?

    Help please
    Thank you So much

  2. Good questions. SP the passive node, it does not have to control the MSDTC
    resource, but it will need to have the local service (Distributed
    Transaction Coordinator) started.

    I have to ask why you are not going to the latest Service Packs for Exchange
    and the OS at this time?

    I have to ask why you are not going to the latest Service Packs for Exchange
    Quite simply, because we operate as a global company, and all changes have
    to be agreed throughout. Once done, we do an implementation. Obviously alot
    of testing goes into this before any rollout.

    But the reapply of SP1 fixes some issues with public folders / address
    books. Unfortunately I cannot test this in a lab on the cluster, as we do not
    have one :-(

    But I will ghost the C: Drive, take an NTBackup as well, then try it on the
    "NON" active node. (which means passive) :)

    Hi Rodney
    Yes, thats correct - alot of testing goes on, but on a "Global" Level,
    rather than each branch office!

    Unfortunately, no test cluster. I have tested this process on a single
    Exchange Server, which worked fine, but in a cluster, its a different ball

    Thanks, S.

    Just to let you know, the reapply of the SP went well.
    Total outage for the users was 2mins and 6 seconds (this was the point I
    initiated a failover and the resources going off line and then coming back
    online. the information store took the longest, but with 600gb+ stores, not

    Still, I felt the failover was quite quick. Any comments welcome.
