How to change my FQDN in exchange

Hi all,

We have recently had emails from some clients rejected due to them doing a reverse dns on our emails, so i have setup the appropriate a and ptr records with our ISP

The a record is now

Trouble is the fqdn name in our virtual server is still myserver.mydomain.local

If i try and replace this with and click the check dns it is unable to resolve it.  Do i need to add a record into my local dns? if so how and what do i need to add

Hello pfocus,

you need to ask you isp for a change of the a-record of, which need to be pointed to the external ip of your sbs server.
After that you need to rerun the CEICW (connect to the internet wizard) in the server management console and change the server certificate to the FQDN of your server.

hi suppsaws,

The a record is already setup, i've tried running the wizard but i get an error saying the wizard cannot set the dhcp scope options.

I thought it was just a case of changing the fqdn in smtp virtual server and maybe creating a local dns entry?

In sbs there is ONE golden rule .... use the WIZARDS.
Don't try to do anything manual on sbs or you will get a messed op domain environment.
Make sure your SBS server is the ONLY dhcp server in the network.
Make sure all the clients point to the sbs server and are dhcp clients.
After the dhcp is setup correctly rerun the CEICW.

My bad, someone had stopped the dhcp service and set them up on static ip's?

grr why doesnt anyone tell the IT support guy these things

Thanks for you help
as far as I can see, the CEICW wizard doesn't offer a chance to change FQDN or Masquerade Domain settings - I thingk for thses u gotta go in and change it in the exchange config

but fair point about using wizards where possible - i thonk this is one level of customisability BELOW the wizards...
