RE: DCPromo RPC Error

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

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.

Hello, I have two Win2K3R2x86 servers. One is in Sydney and one in Melbourne.
The Sydney server is the DC and I would like to make the Melbourne server an
additional DC for the existing domain. The Melbourne server is connected to
Sydney via VPN routers (Draytek) on ADSL internet connections. Both machines
are multihomed - one interface for internal and one external.

When I run dcpromo the AD installation wizard goes so far and then fails
with this message -

The operation failed because:
Active Directory could not create the NTDS Settings object for this domain
controller CN=NTDS Settings, CN=Sydney, CN=Servers, CN=Melbourne, CN=Sites,
CN=Configuration, DC=xxx, DC=yyy, DC=zz on the remote domain controller
sydney.xxx.yyy.zz. Ensure the provided network credentials have sufficient
permissions.
"The RPC server is unavailable."

I used the Administrator credentials and I have no problems using remote
desktop or browsing shares on the Sydney server through the VPN.
The Melbourne server joined the domain okay as a result of running dcpromo
and the server was added to AD Sites (as a server) and Services, and AD Users
and Computers (as a Computer).
Needless to say RPC Server is running on both machines.
DNS on the Melbourne machine points to Sydney okay and visa versa.
I turned the firewall off in Routing and Remote Access for the external
interfaces.
I tried reducing the MTU on the network interfaces that connect to the
routers but the same problem still occurred.
I am at my wits end and would appreciate any advice.
Thanks
Dharmpuri
