    DHCP Backup

    Hi. Each month, I backup DHCP on my Windows Server 2003 machines by right clicking on the servername and selecting 'Backup'. I have a case where I need to restore from that backup, so I right clicked on the server name and chose the Restore option. A Window appears stating that the DHCP service needs to be restarted. However, my DHCP scope is still missing.

    Any thoughts?

    The only barrier to knowledge is the perception that you already have it.

    Another case of Windows backup functions at their finest.

    You have probably already seen these:

    Well, I know how to go through the motions......at least I thought I did. When I backed up DHCP, I saved the config to C:\DHCP Backup and then copy that folder to a network drive for safe keeping. The backup consists of a file called Dhcpcfg, which must be a binary file since it's unreadable. There is also a folder called 'new'. Inside that folder are various log files which coincide with the dates I performed the backup, along with dhcp.pat and dhcp.mdb. From what I can see, everything looks fine......it just doesn't work.

    I have just boxed the server up to ship it to the site. I'll try again on Monday. As luck would have it, it's a small office so it won't take long to recreate the scope from scratch, but I think this was an excellent test that apparently has failed.

    For those that want to know, I found a resolution, tested, and confirmed it works:

    netsh dhcp server export c:\dhcp.txt all

    Copy dhcp.txt to the destination server

    netsh dhcp server import c:\dhcp.txt all

    The thread can be marked 'Resolved'

    Thanks for the update. Another case of Command Line beats GUI.
