Dear all,

 Anyone can advice what is the correct step to migrate my Windows 2003 DC which also is the primary DNS server in our network to another IP address?

 Just change the IP address of this machine and then make sure that the DNS setting is pointing back to its own?

Exactly but do this as well to force the settings:

from a command promt

net stop dns
ipconfig /flushdns
ipconfig /registerdns
net start dns

Then you will be up quickly again after changing the IP.

Cheers,
Stefan

Change the IP address

Then restart the server service and netlogon service (or reboot of course)

Note you MUST restart the netlogon service to change all the SRV records in DNS - otherwise people cant logon :)

Keep in mind you'll need to update your DHCP settings if this DNS server is listed in the scope options / server options.  If you have a backup DNS server listed you should be OK until your clients have a chance to renew their ip addresses.

So the overall step is :

1.Change the IP address of that machine and then make sure that the DNS setting is pointing back to its own.
2.Reboot.
3.type in command prompt:
               a.net stop dns
               b.ipconfig /flushdns
               c.ipconfig /registerdns
               d.net start dns
4.Restart netlogon service by restart the service from the server's "Service" MMC.
5.Done

is that right?
