Hi group,

Recently, I tried to increase the range of DHCP server in the scope property. I don't know why somehow it doesn't allow my to, because it said, "The range is extended less than the specified backward extension. Extend the range in integral of 32 addresses."
I tried different ranges, but still received the same message. Is there something else I need to configure first in order to do so? Would you mind to tell me what should I do to solve this problem?

Regards,

-Mak

I wonder what IP range are you using?
If you want to have less than 254 clients then you can use between 192.168.1.1 and 192.168.1.254

Good Luck.

I assume you're on NT or Win2K, from the error message you got.
Microsoft's DHCP does not cleanly allow DHCP range extension, you must delete and re-create the pool. If this is a pain (many options) then alternatively the DHCP manager will allow you to create a second scope for the same subnet, with the new addresses. Just make sure you don't overlap the ranges, this can end up with duplicate IP addressing.....hard to solve fast.

Good luck,

Ian
