Domain DHCP Scope Change/Re-Add Question

We have a set DHCP scope for a particular VLAN, the problem is the original scope was not defined wide enough and we're running out of leases.

In short, is it possible (Windows 2008 domain) to extend the scope of an originally created scope in DHCP (say the current is from .100 to .200, changing it to make it .30 to .200 for example)?

If not, what is the best way to re-create/copy/migrate that scope over for the new changes?

Unfortunately you will have to delete the current scope and recreate it with the desired ip range.

Simply follow the instructions to increase the range, not the scope.  You could also create a larger subnet as long as you're using only a switching network.

Hello
No, I think you can do it

I have done it in a Win 2003 environment

But you have to accomplish that in a downtime period. No client has to be alive.
Also I suggest, 2-3 days before that, to change the DHCP lease to the minimum time required because either way you will have many conflicts
