Problems of DNS on Windows 7 ping a host within a child domain

Hi, I have a few interesting problems with windows 7 DNS.

Here are the details:

Windows 7 Enterprise 32 bit computer, joined a Win2k3 AD.
my domain name for example of purposes is called corp.example.info.
I have a child domain: prod.corp.example.info and in this child domain
is a host: 'test '.   COMPLETE the test domain name is: test.prod.corp.example.info.
In this case, 'test' is a CNAME, but the error occurs regardless
the type of DNS record.

My problem is that if I ping test.prod I get host not found.
If I ping test.prod.corp.example.info, everything works fine.

If I do a nslookup on test.prod, I get the correct results.
If I do a nslookup on test.prod.corp.example.info I get the correct results.
(This tells me that the files work correctly in DNS)

I have no firewall on my Win7 machine, or something funky.

I have other operating systems in the field: machines RHEL4 and RHEL5, WinXP, HP - UX
and each of them can properly resolve "test.prod" correctly. I have not tried on Windows Alaric, as there is no shortage of it here.

There is no entry in my C:\windows\system32\drivers\etc\hosts file and it is not damaged.

I tried ipconfig/flushdns / release / renew, /register/ etc. nothing works.

I have an IP address in the DHCP scope for this particular machine,
but the machine receives its IP address from the DHCP server (not sure that it of important, but including at least)

All advanced settings on my Win 7 IPV4 stack corresponding parameters of the functional XP machine.

I made trace wireshark on my machine Win7 and XP machines, and here are my results:

WinXP:

(1) client machine sends a query to the DNS server (in this case, my domain controller)
'test.prod '.
(2) DNS server returns a "No Such Name" standard query response

(3) client machine sends a DNS query for "test.prod.corp.example.info."

(4) DNS server returns a response of standard query with the correct record.

Win7:

(1) client machine sends a query to the DNS server (in this case, my domain controller)
'test.prod '.
(2) DNS server returns a response of "No Such Name" use query

At this point, the Win7 machine gives up and returns could not find host.
Naturally, I checked my settings advanced IPv4 and verified that they are identical to the work
XP machine.

Microsoft gurus out there have a preview?

Thank you!

John.

Hi Johnny Soj,.

Your question of Windows 7 is more complex than what is generally answered in the Microsoft Answers forums. It is better suited for the IT Pro Technet public

  • Problem of DNS in Windows 7 wireless connection

    New computer laptop gateway with Windows 7 was to connect to the internet for a month, until a few days ago, when I started to lose the wireless connection often. The only solution was to wait that it will eventually reconnect again. Other computers are connecting wireless with no problems. I get a message that it is a problem of DNS server. He usually tells me that I am connected to the wireless but the connection between the router and the internet is broken. Wired works fine. Suggestions?

    Hi lisina10

     

    You can follow the steps below to check the NIC in Device Manager.
    You can check if you have any exclamation point beside the devices listed. If you have, then there is problem with the card is installed.
    I suggest you to uninstall and reinstall the NIC drivers and check:
    a. click Startand then click Control Panel.
    b. click system and Maintenance, click Systemand then click on Device Manager.
    Note If Control Panel is in Classic view, double-click System, and then click Device Manager.
    If you are prompted for an administrator password or a confirmation, type the password, or click allow.
    c. in the NIC, expand adapter, right click on the devices listed and then click Uninstall.
    d. When you are prompted to confirm that you want to remove the device, click on OK.
    e. restart the computer.

    After the computer restarts, the drivers will be installed automatically. Check after this procedure if you are able to get access to the network.

  • Problem of DNS in Windows server 2012

    Hi guys,.

    I'm a newbie here and I hope to get help with my question.

    I have a server DNS (192.168.1.55/24). Everything is already configured, the IP address and host names are already mapped and is already working. Now the problem is... I example. Metro.com, when I'm in the same segment (192.168.1.x 24) I am able to access example.metro.com using only his "example" hostame in run. (windows + R, then \\example). When I ping, he also responds with the correct address w/c IP is 192.168.1.11 being. Now, I have another VLAN in my network is 10.1.1.0/24 and 10.1.2.0/24, these VLANS are able to see the 192.168.1.0/24 because I have a cisco layer 3 switch. When I use the DNS 192.168.1.55 segment both 10.1.1.x and 10.1.2.x, so I am able to still ping example.metro.com and able to access. But what happens is, I'm not able to access using only the host name-example term. Is there something I need to configure on the DNS server to have it working? I might have exhausted all procedures, but still can't make it work, and I'd really appreciate that someone can give me a help and advice.

    Once again...

    1. I'm on the 10.1.1.0/24 network

    2. I use 192.168.1.55 as DNS (which I am able to ping, btw)

    3. it can translate example.metro.com to 192.168.1.11 when I ping.

    4. IM NOT in MEASUREMENT of ACCESS IT USING ONLY \\EXAMPLE term I can when I'm in the same segment as the server DNS 192.168.1.0/24.

    Thank you!!

  • Nslookup or DNS in Windows 7 problem

    Hi, I ran into the following issue today - I am able to browse the internet normally, however not able to ping a host by name. By address works very well. nslookup is as follows:

    C:\>nslookup localhost
    Server: unknown
    Address: 8.8.8.8

    Unknown can't find localhost: no response from Server

    If the DNS server is set to dynamic, I have the same problem

    C:\>nslookup localhost
    Server: unknown
    Address: 75.75.75.75

    Unknown can't find localhost: no response from Server

    To book more strange, the (java) application I'm working on some crashes - JVM crash, with out even throw a SocketException or anything when I try to connect to a socket on VMnet1, 8, or even on localhost, regardless of whether I use an ip address or a host name.

    Thoughts?

  • Has anyone ever solved the problem of resolution DNS in Windows 8?

    I had my first Windows 8 PC (inspirion 660) and had immediately DNS resolution problems.  Updated to 8.1 and still had problems with DNS resolution.  I am connected to the router via an ethernet cable, no wifi.  I have to flushdns every 30 minutes or more often, just to be able to use the internet.  Have searched and tried the answers online and the only one I see that actually worked for everyone must replace the router.  All the other solutions seem to fail.  All my other computers and devices work fine.

    There is not a widespread (or even localized, as far as I know) problem with the DNS on Windows 8.  If other devices work fine, but your laptop is affected, then there is a problem with your specific machine or settings.  Have manually set you the IP settings on the PC, including DNS servers?  If so, put everything to DHCP.  If this is not the case, try to define the servers DNS 8.8.8.8 and 8.8.0.0 and see if it works any differently.  If so, it's your router or ISP DNS.  If this isn't the case, then it may be that something went wrong on your computer.  Make sure that all Windows updates are installed and that you have the latest chipset and network drivers and the latest firmware BIOS and NIC.

  • Unable to connect to the Internet - DNS error - Windows 7

    Hello

    I have a new (3 months) desktop XPS from Dell with Windows 7 (64-bit), the Motorola SBG6580 Wireless Modem/Gateway and Comcast is my ISP.

    My computer is connected to a modem with an Ethernet cable. Nothing unusual in the installation program. I just plugged my PC and it worked.

    In the last three months everything worked well. Then all of a sudden, from Friday last I can no longer access the internet.

    The connection at the bottom right shows that I'm connected, and every few minutes a yellow exclamation icon above him. Some sites Web opens very, very slowly, some are open to all and another just give a straight error that I'm not connected. It's weird - I can connect to the first seconds when I restart the computer and the speed is extremely fast, and then all of a sudden I can't connect.

    When I right click on the connection icon for helps out sometimes it says "The DNS does not" and sometimes he can't detect any problem (but I can still access all Web sites).

    Now, I also connected with Ethernet cables to the modem game both consoles and they work very well - I can get online, play games, stream movies etc. My wife and I can also connect our iPhones over Wi - Fi, and I can also connect my laptop running Vista by Wi - Fi.

    The problem is just the Windows 7 PC.

    I already googled the problem and tried all the solutions offered - I rinsed and renewed the DNS using the commands ipconfig, I put the DNS manually but nothing seems to work!

    Could this be a virus any? I have McAfee running and I did a scan, but it does not detect. My feeling is that there is a virus which changes the DNS.

    Any suggestion on how I can confirm to you, or what other measures can I take?

    Thank you!

    Hello

    I have a problem with the local domain name resolution when connected via a VPN SSL using anyconnect.

    I've identified it is due to the fact that the assigned DHCP DNS is not by adding a domain suffix.

    I proved this by adding the local domain after the host name, I'm ping.

    On the the ASA5505 ASDM I ensured that the appropriate field is identified on the DNS, but this still does not work.

    Please could someone guide me in the right direction. It should be on the profile that is downloaded or a configuration that automatically adds the correct suffix when DNS queries are sent to the DNS server.

    Hi again,

    I just figured my DNS suffix name resolution problem and I thought I'd share my solution in case it helps you:

    • Connect to ASDM, select VPN remote access, expand access to the network (Client), highlight the group policies.
    • On the right, edit the group policy that you connect your remote users.
    • Screen that comes up, highlight the server on the left and then click on the small arrow to the right to display other editing options in group policy.
    • Fill in the default domain with your internal domain name (for example, mydomainname.local)
    • Click Ok to save and save config to Flash running.

    Test of reconnection to with a client AnyConnect and performing a ipconfig/all.

    For me, I can now see the suffix dns that I defined in the group policy and successfully, I can ping internal hosts by name.

    Good luck!

  • VMWare HA issues / problems of DNS ESX3.5.0U4

    Hi guys,.

    I have the following problems with my VMWare farm.

    VMWare HA:

    I have setup a HA Cluster where I wanted to add two hosts (HP DL585). One installs and configures the HA Agent without any problem. Else we come up with an error message (not enough resources...).  My quality of configured failover is 1 with VC saying I got 0 for the moment. Reservations are not made on only VMs. Strict admission control is turned off.

    There are currently only a single machine virtual on this cluster, which is a virtualized VC, so I didn't get the chance to disable and configure HA

    I read that it was a problem some time earlier with U2, but I guess this should be fixed now...

    Another point is that I have problems with DNS. I have two connections in service at the present time console, one in my backend for iSCSI Connections with IP VMKernel 10.0.0.1/8 and one for management with 172.16.1.180/24 for the frontend. In my opinion the iSCSI SC didn't need to have a connection to the gateway (172.16.1.1) because it is only for an iSCSI SAN in the backend and will be forever. When I try to ping my DNS servers of the console ESX (172.16.1.180) he's trying this address of 10.0.0.1 ping... Do I have to fill my separate LANs to get a connection to iSCSI SC to the bridge or what? Sounds a bit insecure...

    Thanks for advice or comment on that.

    See you soon,.

    Timo

    In this simple case use files static hosts on ESXs and VC with the only front-end SC.
