Transfer child domain objects into primary domain

We have a domain (domain.corp) with two sites (NY, SF)  and a child domain (London.domain.corp). The child domain seems to be causing problems. In the past it was having replication issues and Exchange queing problems. Another tech preformed some pretty radical DNS changes and now we are having extremely long logins in two of the sites in the primary domain. I think that the child domain's default domain policy is being applied to other sites in the primary domain over a slow VPN link. Also a GC in the child domain seems to be advertising for the primary domain. As the child domain only has 6 users and 2 servers (Exchange and DC), it seems unessecary to have it as a seperate domain. I'd like to tear it down and rebuild it as a new site in the primary domain. Anyone have any experience with this?

Here's my plan so far:

1. Convert london from a child domain to a site in domain.corp
    a.  Transfer London mailboxes to PSTs.
    b.  Remove London mail server from domain.
    c.  Demote child domain DC and remove child domain
        1. If the child domain is still visible in primary domain follow this white paper to remove the orphaned objects: http://support.microsoft.com/default.aspx?scid=kb;EN-US;230306
    d.  Promote london DC server as a DC in domain.corp
    e.  Add LondonDC to the London site as a Global Catalog.
    f.  Add the London Exchange server to the domain.
    g.  Recreate users, mailboxes, shares
    h.  Import old mailboxes from PSTs

Any ideas to streamline improve this plan? Thanks for any help.

Hi mrpez1,

Make sure you have a DSNS server on the London Site as well,

i agree there should be no child domain in this scenario - make sure you configures sites and services optimally as you can greatly increase your use of bandwidth and slow links

As far as I can see All that you have mentioned can be summerized in to the following para:

""""" In the past it was having replication issues and Exchange queing problems.
the primary domain over a slow VPN link. Also a GC in the child domain seems to be advertising for the primary domain. """""""

Well for solution :

HAVE YOU TRIED "ZONE DELEGATION" OF DNS. BY THAT YOU CAN SOLVE THE EXCHANGE QUEING PROBLEM AND REPLICATION PROBLEM. AS YOU KNOW WHEN USERS UNDER CHIELD DOMAIN WANTS TO LOG IN OR WANT"S TO MAIL THEY HAVE TO USE DNS AND YOUR DNS IS ON THE OTHER SIDE OF THE SLOW VPN LINK CAUSING THE REPLICATION ISSUES AND EXCHANGE QUEING PROBLEM. MORE OVER, YOU HAVE ALSO CONFIGURED GC IN THE CHIELD DOMAIN CAUSING THE GC REPLICATION IN THE SLOW VPN LINK.

If you take the above in consideration then the solution will be in right direction, I guess.

Thanks and waiting for comment

Sorry to add this part:

YOUR CHILD DOMAIN'S DNS IS POINTING TO THE PRIMARY DOMAIN CONTROLLER AS IT"S DNS AND CAUSING ALL THE USERS IN THE CHILD DOMAIN TO GO THROUGH THE SLOW VPN LINK EVEN TO LOG IN TO THE DOMAIN LET ALONG FOR THE MAIL.

THAT IS WHY YOU CAN HAVE YOUR OWN DNS IN CHILD DOMAIN AND CONFIGURE A DELEGATION IN THE PRIMARY DOMAIN CONTROLLER. THEN CLIENT OF THE CHILD DOMAIN WILL ONLY SEARCH WITHIN IT"S OWN DNS AND WILL FIND IT"S ACTIVE DIRECTORY SERVICE AND WILL NOT GO ACCROSS THE SLOW VPN CONNECTION.

First of all "sorry for the capital letters" I have got no negative intention. But I haven't found the logic behind the solution that's why i commented on the topic.
