W2K to W2K3 Upgrade - DHCP & WINS questions

    I'm preparing to upgrade our Win 2000 domain to Win 2003, but two of the W2K
    DCs are the primary DHCP and DNS servers for the company which means the IP
    addresses cannot be changed. However, I prefer to do fresh installs of Win
    2003 so I was planning on bringing up a new Win 2003 DC with a temporary
    static IP address. I'l configure DNS exactly as the old W2K DC. I'll
    configure WINS to replicate with an existing WINS server ahead of time so it
    has a copy of that DB.

    Last of all I was planning on shutting down the DHCP service on the old W2K
    DC, backing it up, and then restoring it to the new Win 2003 DC using these

    I would plan on keeping the DHCP service on the Win 2003 DC disabled until I
    had demoted and shut down the old W2K DC and used it's IP on the new Win 2003
    DC. Once this step was complete, I would enable the DHCP service after
    ensuring conflict detection was enabled.

    Does anyone see a problem with my WINS and more importantly my DHCP strategy
    since I'll be keeping taking the IP address from the old W2K DC and using it
    on the new Win 2003 DC? Any suggestions or recommendations? Thank you!

  2. I have attempted to use the backup and restore from the gui and have had
    limited success, I would recommend you follow KB325473.

    As far as decommissioning a DC there are a whole bunch of things you also
    need to look at besides dns and dhcp. Have a look at the article I have
    wrote on this at:

    To make life a bit easier, you should consider making your dns servers
    Active Directory Integrated. It will make this migration much easier.
