I have a current DHCP scope of 192.168.1.X with a subnet of 255.255.255.0. I am planning to increase the DHCP capacity by changing the subnet to 255.255.252.0. I recently moved the current DHCP server from a 2003 server to a 2008 server. I have already changed all the static devices. I think I need to unauthorize the current server. change the subnet and reauthorize. If I do this will I lose my reservations? Is there an easy way to do this? I am new to 2008. So far everything I have done has gone without a hitch. I want to keep it that way. Thanks in advance for your help and advice.
