Перезапуск службы dns windows server

Restarting a DNS (Domain Name System) server can vary slightly depending on the operating system and the DNS server software you are using. Below are step-by-step instructions for restarting DNS servers on various platforms.

On Windows Server

1. Using Services Management Console:

   • Press Windows + R to open the Run dialog.
   • Type services.msc and hit Enter.
   • In the Services window, locate DNS Server.
   • Right-click on DNS Server and select Restart.

2. Using Command Prompt:

   • Open Command Prompt as an administrator.
   • Type the following command:

     net stop dns
     

   • Then start the service again with:

     net start dns
     

3. Using PowerShell:

   • Open PowerShell as an administrator.
   • To restart the DNS service, use:

     Restart-Service -Name dns
     

On Linux (BIND)

1. Using Systemd (on modern Linux distributions):

   • Open a terminal.
   • Use the following command:

     sudo systemctl restart named
     

   • You can check the status of the service with:

     sudo systemctl status named
     

2. Using Service Command (older distributions):

   • Open a terminal.
   • Type the command:

     sudo service bind9 restart
     

   • For some distributions, it might be:

     sudo service named restart
     

3. For Other DNS Server Software (like dnsmasq):

   • Use this command:

     sudo systemctl restart dnsmasq
     

On macOS

1. Using Terminal:
   • Open the Terminal application.
   • You can restart the DNS service using the following command:

     sudo killall -HUP mDNSResponder
     

   • This command will restart the mDNSResponder service, which handles DNS on macOS.

Notes:

• Backup Configuration: Before restarting, especially in production environments, ensure that you back up your DNS configuration files.
• Check Logs: After restarting the DNS server, check the logs for any errors or warnings to ensure that the server started correctly.
• Impact on Clients: Be aware that restarting a DNS server may temporarily affect clients that rely on it for name resolution.

These methods should help you successfully restart your DNS server based on the operating system and DNS software you are using. If you encounter issues, refer to the documentation specific to your DNS server software for troubleshooting.

Why is my DNS not connecting?

The “DNS server not responding” error message means that the DNS of the domain you want to reach is unavailable or your browser cannot connect to the internet. Possible fixes include restarting your router or modem, checking for network issues, and updating your browser.

How do I restart DNS services in Windows Server?

You can’t uninstall / reinstall DNS from a Domain Controller so if your DNS server has insurmountable problems, make sure that you have a second DC with a working DNS then dcpromo (demote) the problematic DC, make sure DNS has been removed, then repromote that server to be a DC.

Beyond that the next thing to do is restart the DNS Service which you can do through the DNS MMC console or through SERVICES.MMC .

If you have a DNS server that is not working well or has errors indicating partial corruption there are a few ways to kick the server using simple commands:

1. Open PowerShell as an Administrator
2. Type:

   DNSCMD /Config /BootMethod 2

3. Press the ENTER key
4. Restart the DNS service, or just reboot the whole server if want

I found that it took about 20 minutes for the errors and problems I was seeing to go away and for DNS to start functioning properly.

You can also try to view the DNS servers basic configuration to look for anomalies:

1. Open PowerShell as an Administrator
2. Type:

   DNSCMD /Info

3. Press the ENTER key
4. Look for oddities

DNSCMD BACKGROUND:

According to THIS Microsoft article there are four different sources for DNS start up information:

0 – Clears the source of configuration information.
1 – Loads from the BIND file that is located in the DNS directory, which is %systemroot%\System32\DNS by default.
2 – Loads from the registry.
3 – Loads from AD DS and the registry. This is the default setting

If there is a problem with this command you can place the setting directly in the registry manually:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters\BootMethod

and set it to the number 2.

In future versions of Windows, Microsoft might remove dnscmd.exe.

If you currently use dnscmd.exe to configure and manage the DNS server, Microsoft recommends that you transition to Windows PowerShell.

To view a list of commands for DNS server management, type “Get-Command -Module DnsServer” at the Windows PowerShell prompt. Additional information about Windows PowerShell commands for DNS is available at http://go.microsoft.com/fwlink/?LinkId=217627 .

The DNS server, short for Domain Name Server, is where the management, maintenance, and processing of Internet domain names occur. Or in simple terms, a DNS server assigns an IP address to your PC so that you are easily recognizable on the world wide web. And it does so by translating the domain names to IP addresses.

However, often the server might stop running altogether or have other issues like web pages not getting loaded correctly.

That could be due to some error cropping up, though, in such a scenario, one easy and sure-shot method of getting things back on track is to restart the DNS Server, which is exactly what we discuss in this article.

How can I fix DNS client restart issues?

1. Via command line interface

Картинка с сайта: windowsreport.com

Start command prompt: You can do this either by clicking on Start followed by selecting Run or by simply pressing the Windows and R button simultaneously. When the Run dialog box appears, type cmd and press Enter to start the Windows command prompt.

Alternatively, you can simply type cmd in the Cortana search box, right click on the Command prompt app that shows and select Run as administrator.

Type the command net stop dnscache and press enter. This will stop the service. However, it might take a few seconds for the command to take effect.

You will be shown the following messages:

• The DNS Server service is stopping.
• The DNS Server service was stopped successfully.

Next, type the command net start dnscache and press Enter. This will restart the DNS server though again there might be a few seconds’ delay for that to happen. DNS Server runs as a service in your PC and the above command restarts the service.

The following message should confirm the above.

• The DNS Server service is starting.
• The DNS Server service was started successfully.

2. Via graphical user interface

Картинка с сайта: windowsreport.com

Launch Control Panel: You can do this by clicking on Start > Windows Systems > Control Panel. Alternately, you can also type Control Panel in the Cortana search box and selecting accordingly from the search results shown. You can also right click on the Start menu and select Control Menu.

Under Control Panel, click on System and Security > Administrative Tools and open DNS snap-in.

From the list of options on the left, locate server, right-click on it and select All Tasks. Here, there are Start and Stop options for starting and stopping the service, respectively.

3. Restart DNS Server on a remote server

This is done with the help of the utility named sc, which gets installed together with the OS so far as Windows Server 2003 is concerned. To perform the start and stop DNS operations, here is what needs to be done.

To Stop DNS.

C:> sc \matrix stop dns

SERVICE_NAME: dns

TYPE               : 10  WIN32_OWN_PROCESS

STATE              : 3  STOP_PENDING

(STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN)

WIN32_EXIT_CODE    : 0  (0x0)

SERVICE_EXIT_CODE  : 0  (0x0)

CHECKPOINT         : 0x1

WAIT_HINT          : 0x7530

To Start DNS.

C:> sc \matrix start dns

SERVICE_NAME: dns

TYPE               : 10  WIN32_OWN_PROCESS

STATE              : 2  START_PENDING

(NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN))

WIN32_EXIT_CODE    : 0  (0x0)

SERVICE_EXIT_CODE  : 0  (0x0)

CHECKPOINT         : 0x0

WAIT_HINT          : 0x7d0

PID                : 504

FLAGS              :

This is all you need to do.
