Re: DCPromo RPC Error

Hi Drampuri,
Apologies for the delayed response
This problem is complicated by the fact you have multi-homed DC's.
What's the technical reason for this?

Regards,

Austin

Hi Emmanual,
Yes, sorry I forgot to put that in my post.
Sydney internal is 192.168.0.x and external is 192.168.1.x
Melbourne internal is also 192.168.0.x and external is 192.168.2.x
I have Melbourne and Sydney sites in AD Sites and Services and the Melbourne
server appeared in the Servers folder under the Melbourne site after running
dcpromo. Subnets are also defined.
I still don't know what's up?!
Thanks
Dharmpuri

Hi,

Do you have separate subnet for melbourne?
If your melbourne server's Ip address falls in the same subnet of
sydney's.Then no issues.
If not then either create a separate subnet and associate with the
respective site or create a new site for melbourne and associate the newly
created subnet.
Also follow the steps mentioned in the KB article 272294 to avoid failure of
replication.
