Hi,

I have to set up a new network with a 2003 domain controller, exchange 2003 server etc. I’m still waiting for confirmation on the ip addressing for this network. Are there any risks involved in setting it up with my own private addresses in the meantime, and just changing it later? Will this affect the DNS functionality, exchange server or anything else in any way?

Thank you

Hi woerts,


It's not a great idea to swap ip addresses on a DC and exchange server. It can be done, but you'll have to be careful and check your DNS setup doesn't have a nervious breakdown.


I'd suggest you what until you get the offical addresses. Saves you alot of work.

Indeed, especially if its a global catalog server (check active directory sites and services) is it the only DC on the network? if not ensure another is the GC server and leavi it that way for a day or so. Your biggest problem will be - if your ISP is hosting an MX recoerd for your mail server, if its poiniting straight at the servers IP address it will need to be changed.

Speak to your Network tecchy and find out if you are doing NAT on your network, if you are you will need to chage the static inside outside rule for that servers IP address's (internal and external) If you are NOT doing NAT then your ISP may need to change their MX record accordingly.
