    It seems DNS issue. Before creating the trust you need to setup the DNS.How do you setup your DNS?

    You can use NSLOOKUP for DNS troubleshooting. See the below example.
    cmd---nslookup
    set q=srv
    _ldap._tcp.dc._msdcs.trusteddomain.com
    _ldap._tcp.gc._msdcs.trusteddomain.com
    _ldap._tcp.pdc._msdcs.trusteddomain.com
    _ldap._tcp.dc._msdcs.trustingdomain.com
    _ldap._tcp.gc._msdcs.trustingdomain.com
    _ldap._tcp.pdc._msdcs.trustingdomain.com

    If above test is passed we can say DNS seems OK.

    thanks for the reply, i  guess the problem because of DNS yes as the domain name is ( abc. ) not .local or .com or anything like that it look like a root domain any idea how to fix that.

    How to fix it?


    1. The preferred "fix" (in a one line summary), is to install a fresh new domain properly named and use ADMT to migrate user, group and computer accounts into the new domain from the current domain.

    2. An alternative is to perform a domain rename, (difficulty depends on the operating system and which version of Exchange is installed).

    3. As a temporary resort, you can use the patch/bandaid registry entry to force resolution and registration that is mentioned in the following link. This must be applied to every machine. Unfortunately it must be done on every machine in the domain, including the DCs, member servers, workstations and laptops.
