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.
