You need to update all references to your IP addresses.  That is why it is better to use computer names (DNS) instead of IP addresses.  So, you need to check your firewall settings, any config files that use IPs, any source code that (heaven forbid!) has hardcoded the IP addresses, the hosts file, and so on.  When you have found anything that references the IP address, by all means, change it to the name!  One quick way to find them (but it won't find everything) is to search all of your files for the current IP addresses.  You can use Windows Grep or TextPad to do that.  When you have found something that needs changing, record it in a file for the next time this happens.  Good luck.

do you have a firewall or does the server have the public IP assigned to it?

If your network was setup by a professional then you would need to change the IP address on the WAN interface of your firewall.

you will also need to change the DNS of your public services to reflect the new public IP Address

if your public IP address is configured on your server you should probably call a professional to assist you.

Greg HejlPrincipal ConsultantCommented:
they need an external firewall, small business server 2003 is no longer supported by microsoft.  it is an insecure platform.

the 2003 server has one interface as wan, the other is the lan.

all you have to do is change the wan interface IP,  check the internal dns for the old wan IP Address.  update their external DNS records to reflect the new wan IP

MX Records are wherever you manage public DNS for your domain.

do a who is lookup on their domain.  find the domain registrar and determine where their DNS records are hosted.

if your client has an outside service that forwards their mail to your client, they would know
