SBS 2003 R2 - Can Two SBS Servers Share The Same ISP?
I currently have a SBS 2003 R2 network in place in our office. It's running great. I need to use the same ISP and firewall to temporarily setup another SBS 2003 R2 server with a different domain name for configuration purposes only. I have 5 statice IPs. Can this be done? The second server will be moved to another office once it is configured. Any help will be appreciated.

sure...
if you want the domain name to resolve to your public address just have the authoritative names server for the domain name to point to the IP address.

Do you feel that this may cause "ill" effects to occur in my production environment; only because of SBS limitations? I have heard of SBS servers shutting each other down, etc.

you have one domain name resolving to an IP address and you have another domain name resolving to a different IP address. you forward these to the respective SBS boxes.
These SBS boxes LANs are different subnets.
don't see the problem....
if you try to have 2 SBS boxes [different domains] on the same network, sure your going to have problems, but this isn't the senario you've mentioned. You have a pool of 5 public addresses to use. I assume all 5 go into your perimeter router and that perimeter router then forwards traffic to the appropriate SBS box. Each SBS LAN is a seperate LAN [dual NIC SBS box which is the recommended method for W2003].]

Sharing ISP with SBS
No Problem with having the same ISP. However, inbound mail domain names / static IP addresses will need to be changed when you move to the other office. If you wanted to test inbound mail before shipping then you may have issues with port forwarding in your firewall/router.
If both servers are on the same LAN then DHCP may become an issue since you can only have one authorised DHCP server. Even on different network addresses a DHCP request from a client could erroneously connect to your DHCP if it has become the authorised DHCP server.
I'd suggest connecting the server to a spare switch during initial setup, once all the features are configured turn off the DHCP server service until you ship. You can then test it on your LAN and router functions to ensure mail and web works as required.
