Cannot run Import-DhcpServer or Backup-DhcpServer in Server 2012

    Question

  • Hi Folks,

    We are moving to 2012 DC's. Things are going well except for importing the DHCP config from a 2008 non R2 server. I'm following the advice from this blog, although I am not importing to a failover configuration, just from a single server to another server.

    I have run the Export-DhcpServer cmdlet successfully on the 2012 server to generate the dhcpexp.xml from the remote 2008 server. However, when I try to run the Import-DhcpServer cmdlet to import the configuration:

    Import-DhcpServer –ComputerName mydc.mydomain.org -Leases –File C:\export\dhcpexp.xml -BackupPath C:\dhcp\backup\ -Verbose

    it fails with the following error:

    backup-dhcpserver : Failed to back up the database on server mydc.mydomain.org to c:\dhcpbackup.
    At line:1 char:1
    + backup-dhcpserver -computername mydc.mydomain.org -path c:\dhcpbackup
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : PermissionDenied: (mydc.mydomain.org:root/Microsoft/...P/PS_DhcpServer) [Backup-DhcpS
       erver], CimException
        + FullyQualifiedErrorId : WIN32 5,Backup-DhcpServer

    I next tried not specifying the -BackupPath parameter to Import-DhcpServer, but it prompted me, so it is apparently mandatory. I then tried running the Backup-DhcpServer cmdlet, but it also fails with exactly the same error message. I have tried a variety of different paths, and fiddling with permissions on the the specified folders with no success.

    Can anyone lend me a hand so I can get this wrapped up? Thanks alot,

    ianc

  • I know you may have already tried this, but I have to ask: Did you run the shell as Administrator?

    Or have you tried to back it up to a folder in your profile?

    I assume both DCs (old and new) are in the same domain.

  • Did you tried with the netsh command ? Seem more easy to move that way.

    Check the wiki article http://social.technet.microsoft.com/wiki/contents/articles/8484.how-to-easily-change-a-dhcp-s-scope-subnet.aspx I did some time ago.

    It show how to change the scoop, but it's the same if you migrate, you migrate and import in your other server.

    BINGO!  I've never had to run a powershell console as admin before, but I guess there's a first time for everything.  Thanks for the (excellent) answer to my (stupid) question,

  • A question is only stupid if you don't ask. :-)

    Glad to hear it was an easy fix!
