Configure Disjoint Namespace for Exchange Migration

    Question

  • hi guys

    need help to verifiy some things . i am about to start Excahnge 2007 to Exchange 2010 Migration and Since i found there is  Disjoint Namespace on Domain, some addtional Steps need to be done. here are the details

    Root- Child Domain

    Root Domain : myroot.local( NetBIOS Name - myroot ) , DC = DC1.myroot.local , DC2.myroot.local

    child Domain : company.myroot.local ( NetBIOS Name - Cool ), DC = AD1.company.myroot.local , AD2.company.myroot.local

    Since My Netbios Name is Diffrent , it's beleive i have to configure "Disjoint Namespace" - as per - http://technet.microsoft.com/en-us/library/bb676377.aspx & Exchagne deplyment Assitment Tool.

    i am wonder i need some help to verify name for this change.

    1: Configure the DNS Suffix SearchList - which name should be included on Steps no 8 on this ( http://technet.microsoft.com/en-us/library/bb847901.aspx )

    **********is it "company.myroot.local, Cool" ( FQDN for child domain & DNS Name )

    2: modify msds-allowednssuffixe attributes - which name should be included on Steps no "d" on this  http://technet.microsoft.com/en-us/library/aa998420(v=exchg.80).aspx

    **********is it same "company.myroot.local, Cool " ( FQDN for child domain & DNS Name )

    i am confious with this names and any once can help me to verify this, that would be great.  "cool" my NETBios Name for Child Domain

  • Hi ,

    We need to add the primary DNS suffix of the disjoint computer :“myroot.local”

    the DNS domain name: From a Command Prompt window, type set. The variable USERDNSDOMAIN displays the DNS domain name.

    And also type any additional namespaces for other servers with which Exchange may interoperate.

    If the child domain also be configured NetBIOS domain name different with DNS domain name, it need to do above same steps.

    We need to add DNS suffix use msDS-AllowedDNSSuffixes whenthe DNS domain name for the computer does not match the Active Directory domain name. that is the name you asked is DNS suffix of the disjoint computer.

  • hi thank you for the reply. in my case , only Child domain DNS name is diffrent. so as i understood, my guess is correct.

    1: Configure the DNS Suffix SearchList - which name should be included on Steps no 8 on this (http://technet.microsoft.com/en-us/library/bb847901.aspx )

    **********It is  "company.myroot.local, Cool" ( FQDN for child domain & DNS Name )

    2: modify msds-allowednssuffixe attributes - which name should be included on Steps no "d" on this  http://technet.microsoft.com/en-us/library/aa998420(v=exchg.80).aspx

    **********it is  "company.myroot.local, Cool " ( FQDN for child domain & DNS Name )

    thank you
