Hi

Is there any risk if I change the IP address of Domain Controller.
Dns server is configured on DC.

Hi,

Well there are risks in everything in live bud but there should not be
in this case.
Just remember after following the article below run the following from
the command prompt
ipconfig /flushdns & ipconfig /registerdns & net stop netlogon & net
start netlogon.

Make sure to change the clients to point to the new address.

Good luck

just to be sure...

before the IP change, if the DC is hosting DNS AND it is pointing to itself
as preferred DNS, configure the DC to use ANOTHER preferred DNS and use
itself as alternate....

Then change its IP

Then:
ipconfig /registerdns
nbtstat -RR
net stop netlogon & net start netlogon
net stop dns & net start dns
reconfigure TCP/IP settings so that it points to itself for DNS as preferred
and to another DNS server as alternate..


besides that you need to change EVERY system/application/service that points
to that DC (because of something it hosts, e.g. DNS or WINS) by its IP
address.... servers/clients may need to change their TCP/IP settings and
DHCP scopes may need to be adjusted. And there may be more!
