Hi Guys,
My company is moving to a new premises at the end of this month.
We are currently using SBS2003 Basic with 5 clients.
May i know what setting need to be changes, we will be having a new
ISP, which means new static ip address (single) and DNS.
We are also currently using SMTP for emails.
many thanks

Basically, you only need to rerun CEICW to change DNS forwarders and IP
settings (if you have a router in front of SBS you don't even need to change
the IP settings).
Also, you would need to change your *public* DNS records to reflect the new
IP on your A/MX records.
Cheers,

To embroider upon Javier's reply...
If you use an external firewall appliance (which you really should be, with
SBS Standard), it should be doing NAT for you. So all you need to change is
the public IP information in the firewall/router, and perhaps your DNS
forwarders in your SBS DNS server (although that isn't even required; you
can get away with using other ISP's DNS servers). If you don't have a
hardware appliance of your own and were relying upon NAT in your current
ISP's equipment which is going bye-bye, get thyself a firewall. I personally
like Sonicwalls, but there are many decent options out there. I don't
recommend the built-in SBS firewall to protect your network, although some
like it just fine.
And then contact whomever hosts your public DNS to have them update the IP
address in the A record that your MX record points to.
Before you do this, make sure you have another MX record that points to
someone else, for backup (aka store & forward). If you can't find anyone to
do this for free, such as your new ISP or DNS host, look at MailHop BackupMX
from www.dyndns.org - it's inexpensive and works well. That way, you won't
lose mail. |
