    You can also use following command to resolve this problem.

    1) net stop dnscache

    2) net start dnscache

  2. Ping uses the DNS Client service and I think nslookup establishes a winsock connection. Try to stop DNS client service to see if it might help. Make sure you are trying to ping from a client that is joined with the ADC.

    Use these commands to reset some of the network states:

    As Torai suggested try to flush DNS resolver cache : ipconfig /flushdns
Reset TCP/IP stack to defaults : netsh int ip reset reset.log
Flush routing table : route /f (reboot required)
Reset WINSOCK entries to defaults : netsh winsock reset catalog

    I hope that helps.

  3. I had an issue like this recently turned out to be the netbios cache was out of date.

    Try flushing it using

    nbtstat -R

    then ping again

  4. Please restart Dnscache services. Go to services.msc --> Click on DNS Client and than restart.

  5. From the Domain controller ping domain.com If still the issue then run below command from cmd devmgmt.msc uninstall the network card from the console. Later select "Scan for hardware changes" and the network will be back again.

  6. You probably need to flush your DNS. nslookup is going to the server for it, but local DNS has it cached.

    ipconfig /flushdns

  7. I had the same problem. I went and turned off firewall and it worked. Usually systems with FireWall enabled do not allow pinging in certain cases. Go to PowerShell. Type in the following.

    netsh advfirewall set allprofiles state off

    The next line should be generated as

    Ok.

    Try pinging your domain name now. Hope this helps! Thanks.
