    Did you try looking into %windir%\system32\sysprep ?

    Yes I did look into Sysprep.  If I use sysprep it will wipe out the IP settings and I will not be able to remote-in after reboot.

    Let me know if there is any alternative

    try psexec tool from SysInternals
    On management workstation install above tools and run below command in elevated command prompt
    psexec \\remote_computer_IP cmd
    This will open command prompt on remote computer
    then navigate to %systemroot%\system32\sysprep folder and run below command
    sysprep /oobe /generalize /reboot
    the command will change SID and hostname of machine and reboot the machine
    note that this will take machine out from domain

    Note that you have to have local admin rights on remote machine

    I am hoping for a tool that will keep my IP Settings.  Is this possible?

    If this is 2003 server, SysInternals tool is available to change SID without changing IP address
    However utility is not available for 2008 onwards
    One possibility could be setup dhcp server to lease IP after sysprep, find out IP from DHCP and connect to server again and then change IP to desire one.

    My machine at the remote sites only uses static IP addresses so I am guessing there is no way out.
