Xakamaynta Domain^{(Domain Controller)} Directory Active ( AD DC ) ee bogga lama xidhiidhi karo

Si aad u hagaajiso Hagaha Active Domain Controller ( AD DC ) ee goobta lama xidhiidhi karo, raac tillaabooyinkan:

1. Hubi heerka Ping
2. Ku dar^(Add) maamulaha domainka IP liiska DNS
3. Ha isticmaalin DNS Public
4. Bilow adeegga macmiilka DNS
5. Ku biir^(Join) aaladda bogga Hagaha Firfircoon^{(Active Directory)} ee deegaanka

Si aad wax badan uga barato tillaabooyinkan si faahfaahsan, waxaad u baahan tahay inaad sii waddo akhriska.

1] Hubi heerka Ping

Waxay u badan tahay inay tahay waxa ugu horreeya ee ay tahay inaad hubiso si aad u hubiso in domainku hadda online yahay iyo in kale. Haddii domain-ku aanu adiga kugu habboonayn, kuma xidhi kartid adiga oo raacaya hab kasta. Sidaa darteed, samee waxyaabaha soo socda si aad u hubiso inaad heli karto natiijo ping togan iyo inkale:

• Riix  Win+R  si aad u furto Run .
• Ku qor  cmd  oo taabo  badhanka Gelida  .^(Enter )

• Guji  badhanka OK  si aad u badbaadiso isbedelada

Taas ka dib, waa inaad awood u yeelatid inaad ping domainka oo aad ku xirto.

3] Ha isticmaalin DNS Public

Isticmaalka DNS-ka Dadweynaha^{(Public DNS)} waxay abuuri doontaa isku dhacyo badan markaad isku daydo inaad ku xidho domain. Dad badan ayaa inta badan u dooda in ay isticmaalaan DNS Public^{(Public DNS)} meesha laga  doorbidayo serverka DNS^{(Preferred DNS server)}  iyo  serverka kale ee DNS^{(Alternate DNS server)} .

Waxaad u baahan tahay inaad isticmaalayso server-ka DNS ee uu maamulahaagu bixiyay. Haddii aad tahay maamulaha, waxaad u baahan tahay inaad isticmaasho faahfaahinta server-ka DNS si la mid ah ^(DNS)kantaroolaha Domain^{(Domain Controller)} -ka ama kumbuyuutarka martida loo yahay.

4] Bilow adeegga macmiilka ee DNS

Adeegga Macmiilka DNS^{(DNS Client)} wuxuu u baahan yahay inuu gadaal ka socdo si uu u isticmaalo server-ka DNS ee kumbiyuutarkaaga. Haddii fursad kasta, ay naafo tahay ama la joojiyo, waxaad la kulmi kartaa dhibaatadan. Sidaa darteed, samee waxyaabaha soo socda si aad u xaqiijiso in adeeggu socdo iyo in kale:

• Ka raadi  adeegga macmiilka DNS ^{(DNS Client )} oo laba jeer guji.
• Haddii xaaladdu  istaagto^(Stopped) , dhagsii  badhanka Start  .
• Guji  badhanka OK  si aad u badbaadiso isbeddelka

Intaa ka dib, dib u bilaw kombayutarkaga si aad u hubiso in ay xalinayso arinta iyo inkale.

5] Ku biir^(Join) aaladda bogga Hagaha Active^{(Active Directory)} ee deegaanka

Markaad isku daydo inaad ku darto akoon shaqo ama dugsi^(School) , waxay ku siinaysaa ikhtiyaar aad ku darto ama ku biirto aaladda domainka Hagaha Firfircoon ee deegaanka si toos ah. ^{(Active Directory)}Waxaad isticmaali kartaa doorashadan si aad u xalliso dhibaatadaada. Taas awgeed, raac talaabooyinkan:

• Riix  Win+I  si aad u furto Settings Windows.
• Tag  qaybta xisaabaadka ^(Accounts ) oo dhagsii liiska  shaqada ama dugsiga ^{(Access work or school )} .
• Guji  badhanka Connect 
• Guji  aaladda Ku biir ^{(Join device to a local Active Directory domain )} ikhtiyaarka Hagaha Firfircoon ee deegaanka.
• Geli^(Enter) magaca domainka oo dhagsii  badhanka Xiga ^(Next ) .
• Geli^(Enter) magaca isticmaalaha iyo erayga sirta ah ee maamulka
• Geli^(Enter) macluumaadka xisaabta oo dooro  nooca Koontada^{(Account type)} .
• Dib u bilaw kombayutarkaga

Ka dib marka dib loo bilaabo, akoonkaaga iyo kumbuyuutarka waa in lagu daraa domainka iyada oo aan la helin fariinta qaladka ee kor ku xusan.

Sideen u hagaajiyaa maamulaha domain-kayga DNS ?

Si aad u xalliso arrinta maamulaha domainka ee DNS , waxaad u baahan tahay inaad geliso faahfaahinta server-ka  DNS saxda ah ee guddiga Xiriirinta Shabakadda ^{(Network Connections )} . Waa inaadan isticmaalin DNS Public^{(Public DNS)} midkoodna.

Sideen ku xidhi karaa maamulaha domain AD?

Si aad ugu xidhidhiyaha Ad Domain Controller^{(AD Domain Controller)} , waa inaad gelisaa dhammaan server-yada DNS ee saxda ah ee ku dhex jira  guddida ^(DNS)Xidhiidhada Shabakadda ^{(Network Connections )} . Marka labaad, waxaad furi kartaa qaybta  "System Properties  panel", guji  badhanka Beddelka ^(Change ) , u beddel  menu Domain  , oo geli domainka aad rabto inaad ku xidho.

Waa intaas! Kuwani waa qaar ka mid ah xalalka shaqada si loo hagaajiyo arrinta Xakamaynta Domain AD^{(AD Domain Controller)} .

Active Directory Domain Controller for the domain could not be contacted

While connecting to a domain or changing the compυter name, if you are gеtting An Active Directory Domain Controller (AD DC) for the domain “domain-name.com” could not be contacted error, here are some troubleshooting tips and tricks to fix this issue. It may appear due to a typing mistake or some other internal issues. Either way, you can fix it by following these guides. The entire error message says:

An Active Directory Domain Controller (AD DC) for the domain “domain-name.com” could not be contacted.
Ensure that the domain name is typed correctly.
If the name is correct, click Details for troubleshooting information.

The Details menu doesn’t always help you fix the problem, and that is why you should follow these tips and tricks to get rid of it.

An Active Directory Domain Controller (AD DC) for the domain could not be contacted

To fix An Active Directory Domain Controller (AD DC) for the domain could not be contacted, follow these steps:

1. Check Ping status
2. Add domain controller IP in DNS list
3. Don’t use Public DNS
4. Start DNS Client service
5. Join device to local Active Directory domain

To learn more about these steps in detail, you need to keep reading.

1] Check Ping status

It is probably the first thing you should check to ensure that the domain is currently online or not. If the domain is not up for you, you cannot connect to it by following any method. Therefore, do the following to check if you can get a positive ping result or not:

• Press Win+R to open the Run prompt.
• Type cmd and press the Enter button.
• Type ping domain-name.com and press the Enter button.

If it shows ping results with multiple and continuous replies on the Command Prompt window, you can go ahead with other solutions.

2] Add Domain Controller IP

The host and all the other computers should carry the same DNS servers to be connected to a Domain Controller. However, the computer shows the aforementioned error message; it is most likely causing due to the wrong DNS servers. To confirm that, do the following:

• Press Win+R to open the Run dialog.
• Type ncpa.cpl and hit the Enter button.
• Right-click on the Ethernet and select Properties.
• Double-click on the Internet Protocol Version 4 (TCP/IPv4).
• Make sure you have the correct IP address, Subnet mask, and Preferred DNS server.
• If not, ask your admin to provide the correct details and enter them accordingly.
• Click the OK button to save the changes.

After that, you should be able to ping the domain and connect to it.

3] Don’t use Public DNS

Using the Public DNS will create more conflict when you try to connect to a domain. Many people often tend to use Public DNS in the place of Preferred DNS server and Alternate DNS server.

You need to be using the DNS server that your administrator has provided. If you are the admin, you need to use the DNS server details the same as the Domain Controller or the host computer.

4] Start DNS Client service

DNS Client service needs to be running in the background in order to use any DNS server on your computer. If by any chance, it is disabled or stopped, you may come across this problem. Therefore, do the following to verify the service is running or not:

• Search for services in the Taskbar search box.
• Click on the individual result.
• Search for the DNS Client service and double-click on it.
• If the status is Stopped, click the Start button.
• Click the OK button to save the change.

After that, restart your computer to check if it resolves the issue or not.

5] Join device to a local Active Directory domain

When you try to add a Work or School account, it offers an option to add or join the device to a local Active Directory domain directly. You can use this option to solve your problem. For that, follow these steps:

• Press Win+I to open Windows Settings.
• Go to the Accounts section and click on the Access work or school menu.
• Click the Connect button.
• Click on the Join device to a local Active Directory domain option.
• Enter the domain name and click the Next button.
• Enter the administrator username and password.
• Enter the account information and choose the Account type.
• Restart your computer.

After restarting, your account and computer should be added to the domain without getting the above-mentioned error message.

How do I fix my domain controller DNS?
