Hi we are running out of IP's on our network and we want to change the subnet mask to increase the available IP's on our network. We are currently running a mask of /23 and want to move to a /21. We have a flat network with no routers and using DHCP. I will like to know if by changing the mask on our network will cause any issues with AD 2003 and Exchange 2003? We are not running a exchange cluster.
Base on my experience, after we change the subnet mask,please ensure that the network communication between these machine is good. Thus,I think exchange can work normally.
