Hello everyone,

is there anyway to edit the value of the "first replication partner" of
a DC in win2k AD using Ntdsutil ora any other utility.

any info will be higly appreciated.

thanks

What are you trying to accomplish?

You can create manual CONNECTIONS in Sites and Services.
 
let me try to explain, things in detail,
we have a single domain, mydomain.com, the
PDC machine with the name pdc is at locarion A,
is the global catalog server(i.e pdc.mydomain.com is GC)
also the AD integrated DNS is on pdc.mydomain.com.
An ADC at location A is the Infrastructure Master.
Hence the site A has 2 servers pdc.mydomain.com
and im.mydomain.com.

We have a number of locations across various cities.
We have ADC's at all of these locations. None of
them is a GC, all have the DNS pointing to pdc.mydomain.com.

In in inter site links, we have set up links
for all to replicate with location A. i.e say location B
adc_B.mydomain.com, will have a intersite link
between pdc and adc_B. ADC at location C (adc_C.mydomain.com)
will hav intersitelink between pdc and adc_C, and so on.

Now , when i run a dcpromo on site D, to join the domain as ADC
with an intersitelink between pdc and adc_D, why does it pickup
any random location like adc_B as its "first replication partner"
i want it to take pdc as its first replication partner, becos suppose
if i continue with dcpromo, and subsequently try to demote
this server, then again it looks for its "first replication partner" the adc_B
even when there are no intersite links between them.

i hope u undertand wht i am trying to say ...

plz help

Ok, two DCs (It's a poor idea to name them this way as these
roles can be moved from one DC to another as need dictates.)
We have a number of locations across various cities.
We have ADC's at all of these locations. None of
them is a GC, all have the DNS pointing to pdc.mydomain.com.

You should have at least one GC in each SITE -- probably in each
location.
In in inter site links, we have set up links
for all to replicate with location A. i.e say location B
adc_B.mydomain.com, will have a intersite link
between pdc and adc_B. ADC at location C (adc_C.mydomain.com)
will hav intersitelink between pdc and adc_C, and so on.

DC's don't have "site links" -- sites have site links.
The KCC uses these Sites Links to decide how to create connections
between actual DCs.

You can create your own connections but it is usually preferable and
easier to let the KCC do this.
Now , when i run a dcpromo on site D, to join the domain as ADC

Because of Site Link costs probably.
if i continue with dcpromo, and subsequently try to demote
this server, then again it looks for its "first replication partner" the adc_B
even when there are no intersite links between them.

Make sure all sites that have wan links are joined using a SITE LINK in
Sites and Services. Let the KCC then create the connections.

Do not (bother) to directly join sites that have no actual WAN connections.

Make the Site Link "costs" ROUGHLY in inverse proportion to the WAN
speed (add a penalty for any that are the same speed but less desirable),
e.g.,

T3 == cost 3
T1 == cost 100
ISDN == cost 1000

Something like that.
