Change the ip of a Exchange Server

Hi,

I need to change the IP of my Exchange production box and i would like to hear from you guys known implications in doing this.

My plan is to first the IP of its entry in DNS, log into the box and then change the ip of the server.

My main concern is how/when the clients will resolve the name to the new ip ? How long should it take for the dns to be propagated ?

I know i could force all clients to flushdns and therefore ask my dns server other than using the machine cache, but that would be quite a work to do in my company.

Suggestions ?

All went fine.
Only thing i want to add is that, once i did all DNS changes and firewall changes and ip reconfiguration, i also had to change the ip on the configuration for IIS for the OWA.
Quick and easy all is fantastic now!!

Thank you all

i thought it would be valid to add this piece of info:

I had to go to the System Manager of my Exchange box and:

Go to Administrative Groups -> Select the name of your Group -> Servers -> Name of your server -> Protocols -> POP3 and change the ip in there as it still had the old ip.

I did that because my ticket management system was not fetching emails.
:D
Hope it helps you, first day of new exchange ip and everybody is happy!
Just this happened so far and a couple of printers had ip hard coded to them
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
