can not remove superscope form DHCP
HI all,
I have a windows 2003 cluster and DHCP is in cluster mode.
I have 2 remote sites
head quater: 192.168.10.x/24
remote site 1: 192.168.11.x/24
remote site 2 192.168.12.x/24
both remote site are connected with a lease line to the head quater.
my dhcp is giving addresses to all sites.
when I create my dhcp I made a mistake. I create a super scope and then I create my 3 network range (192.168.10, 11 and 12)
after a few weeks, I found that the superscope was a problem so I just right click on all scopes and select "remove from super scope" and everyting is going fine.
BUT, when the DHCP service is restarting (cluster faild over, server reboot, service restart), every scope return in the superscope. it does not seems to save the configuration
when I right click my DHCP server, and select "restart" I receive the error message: not unough storage is available to complete this operation
and the hard disk with the DHCP database that is associated with my dhcp cluster group has 16Go free in event viewer I only have "application hang" event id (101)
Hanging application mmc.exe, version 5.2.3790.3959, hang module hungapp, version 0.0.0.0, hang address 0x00000000.

It's pretty easy to backup DHCP:

I know I can backup my DHCP, uninstall DHCP service, reboot, re-install dhcp and retore DHCP database
but, will I backup my superscope problem too?

ok, it seems to be way more complicated than I expect...
DHCP is installed in cluster. (node 2 is the owner)
So I backup the DHCP database (action, backup), it works
the I take the DHCP group and "take offline"
on node 1, I uninstalled DHCP, re-install DHCP
start DHCP console
add a new server (put the IP of the server, nothing to do with cluster)
I now have a DHCP running on this server in "local mode"
the I select action, restore, select my DHCP backup
I reveive a message saying that service has to restart to complet the operation. click ok.
then again: not unough storage is available to complete this operation
DHCP console freeze
then, don't know why, the cluster DHCP restart...
