How to Delete all DHCP scopes from MS 2008 DHCP

Hi,

I have imported a netsh file into my 2008 dev server. Now I want to remove them all and start blank.

I dont want to have to click one by one and select delete. It will take to long. Is there a quick way to delete all without deleted the DHCP server

Thanks

You can try to remove the dhcp server role, specifying that you also remove the data and configuration. Then reinstall the dhcp server role.
The other way around might be to use a netsh script file. Since you have the original file, changing it to delete the scopes it added might be a matter of find/replace command.

Great.  So what would be the command to delete the Scopes if I use find/replace ?

replace
"add scope"
by
"delete scope"

However, add scope has more parameters than delete scope.
Now, if all your scopes have the same subnet mask (or if there are few subnet masks) you can:
1/ replace "add scope" by "delete scope"
2/ replace "255.255.255.0" by "DHCPFULLFORCE"
(I used 255.255.255.0 as the subnet mask to be replaced. If you have 4 different subnet masks, use them all, one after the other, as the string to be replaced by DHCPFULLFORCE)
