Re: Migration from sbs 2003 to 2008 standard

Hello matttt897,

Nothing will replicate with DNS server change but the client will renew it's ip address from the DHCP server after the half lesae time. At that moment the client will get the new settings from the server, if you have changed the scope options in the DNS management console.

If you do not need the SBS DNS server remove it from the scope options and use only the 2008.

Think i missed somewhere the part with DNS on the new DC. I assume it is installed, if not install the DNS server role from the server manager, choose roles and checkmark DNS server. On the SBS machine make sure to use AD integrated zones, highlight the forward/reverse lookup zone and in the left pane you see the kind of zone. If not AD integrated change them to, easier with adding new DNS servers. Every zone information will be copied to the new DNS without any configuration.

Best regards

Hello Meinolf, Thanks also for the quick response
As i'm still not the brightest network guy on the planet can you help
me
with the "You have to change the DNS server on the clients with the
DHCP
scope options(cahnge
the order if both are still in), or unfortunal manual at the machine
if you
use fixed ip's, next reboot or DHCP lease refresh the clients will use
the
new settings"
Do you mean I need to change the client machines to Preferred DNS (new
2008
box) secondary (old box)???? Also you mention that somehow it will
replicate
over to the clients.
thank you too for your patience!

Hello matttt897,

Ace gave you already the proper configuration detail's for DNS. To
disable IPv6 seee this article:

You have to change the DNS server on the clients with the DHCP scope
options(cahnge the order if both are still in), or unfortunal manual
at the machine if you use fixed ip's, next reboot or DHCP lease
refresh the clients will use the new settings.

Also keep in mind that normally only the SBS DC can have the FSMO
roles, so you should think of removing the SBS if everything is
runnning with the new DC.

Additional as Ace already pointed out you should not multihome the
new DC. Better connect your router to the switch awhere also the new
DC is connected. This prevents you from problems in the future with
GPO processing, logon problems, etc.

For remote access, if needed configure an additional member server,
do not use the DC for that.

Thanks for being so responsive to this. I changed the DNS settings
on
both
the server side nic from the SBS and the 2008 nic too. Each one has
themselves as the preferred DNS. I went into DHCP, under ipv4 i
right
clicked
and added the two options which already had option 006 and 015. I
left
ipv6
alone. which i can hopefully remove later.
I should be able to check the config now?
Do I need to manually change the DNS on each client to preferred
(2008
box)
and secondary (SBS) or does it magically work.
I like when things magically work.

Thanks ace for being so patient. I'm having trouble figuring out
how
to
set
themselves as the first entry in DNS, also in DHCP. Do I change
the
DHCP
on
the new box only?
I haven't done this kind of stuff in ages!
Thanks again
Patience is a virtue!

On the DCs, I assume you know how to get into network properties.
Control Panel - Network Properties, on 2008 it's Manage Network
Settings. Go into the NIC properties, IP properties, and change
just the DNS address section. Make its own IP as the first one, the
partner DC as the second one.

Yes, if you are using DHCP on the new server, go into DHCP
properties, expand the scope, you will see the Scope Options. Right
click, configure options. Change it in there. Also make sure you
have your WINS addresses set in Option 044 and 046 as:

044 = new server IP
046 = 0x8
