Got "The address range and mask conflict with an existing scope" while trying to add the second scope

We have only two DC (windows 2003 servers). Both are DHCP server. One has been with the scope -- the only one on this DHCP:
10.10.50.101 - 10.10.50.175 / mask 255.255.255.0
When I tried to add one scope
10.10.50.176 - 10.10.50.250 / mask 255.255.255.0 to the other DHCP server, I got the error:
"The address range and mask conflict with an existing scope"

I really cannot figure out why I am not able to do it. Can you please help?

The reason is that your original range already claims the scope of 10.10.50.0 so all you need to do is edit your range on that scope to include the new addresses you want in the pool

Edit your Address pool to go from 10.10.50.101-10.10.50.250

Now on your first server create an exemption for the range 10.10.50.176-10.10.50.250 and on your second server create an exemption for the range 10.10.50.101-10.10.50.175

Thank you for the prompt reply. But I swear I did my way and it was working in the past. Do you know if what you suggest is new?

Never mind. I got it. It is because I had a deactivated scope within the same subnet in the server 2 so I wasn't able to add the other scope. After I deleted the deactivated one, it is working now. Thanks.

No it isn't new but I have found there is usually more than one way to skin a cat.

You may even get a response on how to make your example work but the way I gave is the way I would do it myself.
