Servers:
Exchange 2000 SP3 +  patches via WSUS

Windows 2000 server Sp4 Patches

DDNS /DHCPrunning on Linux Bind 9.  

I have changed a subnet from 255.255.255.0 to 255.255.254.0, but now I need to go one stage further and change and change the IP address and subnet
from a 192.168.0.0/23 to a 172.18.0.0/16 address.
Firstly is this possible? I believe that it is.
Also what should I lookout for, I was planning just to update the DNS (DHCP will be changed for desktops)  and then change the addresses on our 2 DC W2k Boxes (one has exchange), then change the ip restrictions we have inplace on the SMTP and IMAP servers.
I will aslo update any site information, firewalls, routers etc.

Is there anything else I should note?

Thanks


Mike

It certainly sounds doable, but I think that should be 172.16.0.0, not 172.18.0.0:

Exchange doesn't care if it's IP address gets changed.  You might want to check in ESM and IIS Manager that the Virtual Servers are all set to listen on 'All Unassigned'.  If not, then this is something else you will need to change.

Mind you, there's nothing to stop you using 172.18.0.0 - it just seems an odd place to start.
