Mboppe - what do you think ISA server is? What did you think the Publishing rules within ISA do?
Rifai,
Nothing much really to change on ISA server itself except any public IP addresses on the external ISA nic. Becasue you will be natting outbound the trffic, this will not change. As you publish the internal services to te internet, that part will not change either.
If you hve public IP(s) on the external NIC these must all change to match your new ISP's allocated range. If you do not use public IP's on the external ISA nic but forwar taffic from your extrnal rout, then this is where the changs will need to occur.
The link that Mboppe has given is a good coverage of he DNS changes required to set up your new MX records. Be aware that the DNS canges are not instantaneous and need to propagate around the Internet and could, in some instnces, take a number of days fo everyone to pick up the new addrsses.

Not much,Correct me if I am wrong.
Isn't ISA a another firewall where you need to allow the incoming trafffic on particalur port.Rifai is using the public IP for the exchange server when is changin the IP does he need to change in the ISA to allow smtp traffic to the new IP(new rule)

on ISA you need to change all the enetries which are pointed to your current real IP.Like you might have opened port 25 for your current Ip.you need to change it.
Why don't you have a firewall and then use NATing with private addresse to your internal network.
