    Hi,

    I've trying to join my windows 7 machine (professional build 7600) to windows 2003 domain. My domain is my DNS & DHCP server.
    When I try to join the domain it gives an error "An attempt to resolve the dns name of a domain controller in the domain being joined has failed. please verify this client is configured to reach a dns server that can resolve dns names in the target domain"

    I have done everything manually put the DNS IP address which is my domain controller IP but still same error ..

    Need Help please !!!!

    Welcome to TSG!

    can you ping the Domain Controller using the FQDN? (Fully Quallified Domain Name)
    On the server, right click My Computer, click Properties
    Click the Computer Name tab
    Note the name shown on the Full computer name: line
    On the Win 7 system:
    Click Start, type cmd, press Enter
    Type Ping FQDN and press Enter, using the name you noted above as the FQDN
    Do you get 4 replies, or something else?

    Hi,

    Thanks for replying .... when I ping FQDN it gives me "ping request could not find host please check the name and try again" but when I only ping the domain name not the FQDN it give me a reply ...

    Thanks.

    Sounds like a DNS problem for sure. You should be able to ping the server name, the domain name, or the FQDN and get a reply for all three.
    Here's what I get:
    Server Name - Win2k3-ent
    Domain Name - test.contoso.com

    Code:
    Microsoft Windows XP [Version 5.1.2600]

    C:\Documents and Settings\TheOutcaste>ping Win2k3-ent
    
    Pinging Win2k3-ent.test.contoso.com [192.168.1.1] with 32 bytes of data:

    When you check your DNS Entries, is the server listed?
    If you don't have the Server set to use itself for DNS (127.0.0.1), it may not register itself with DNS, so won't be listed, or findable.
    Click Start | Run, type dnsmgmt.msc, press Enter
    Expand DNS\ServerName\Forward Lookup Zones and highlight the domain. The right side should look something like this:

    Code:
    Name                      Type                           Data
    _msdcs        
    _sites        
    _tcp        
    _udp        
    DomainDnsZones        
    ForestDnsZones        
    (same as parent folder)    Start of Authority (SOA)     [80], win2k3-ent.test.contoso.com., hostmaster.
    (same as parent folder)    Name Server (NS)             win2k3-ent.test.contoso.com.
    (same as parent folder)    Host (A)                     192.168.1.1
    [COLOR=Red]win2k3-ent                 Host (A)                     192.168.1.1[/COLOR]

    Ipconfig /all for the server:
