    I have been given a task of migrating NLB from Windows 2000 OS to Windows
    2003. My current setup is,

    a) 2 boxes with Windows 2000 Advanced Servers OS running NLB.
    b) NLB setup with single adapter with unicast mode.
    c) Only allowed ports are 80 and 443.
    d) Rest of the settings are as per NLB.
    e) All nlb servers are member servers to a Windows 2003 Active Directory

    Here is what I intend to do.
    a) Backup the configuration on the boxes. ie. ip settings, routing table,
    nlb settings, nlb registry, host files, web server config etc.
    b) Install Windows 2003 on the same box (no hardware upgrade).
    c) Apply the config back onto new Windows 2003 setup.

    My doubts are
    a) Will this work? What tools can I use to backup the existing config?
    Will all my settings be restored eg ip address, routes, nlb settings, etc.
    b) Is there an easier way to do this?
    c) I dont want to go through the route of upgrading to Windows 2003. I
    rather prefer to do a fresh install. Is that ok?
    d) Has anyone done this before and has it worked?
    e) Do I need to be aware of any other details before doing this migration?

    Thanks in advance.

  2. Hello nirvana,

    To upgrade/migrate IIS with load balancing better choose IIS newsgroup:

    or maybe:
