    Active Directory Domain Controller (AD DC) Could Not Be Contacted [SOLVED]

    When your users report that they see “an active directory domain controller for the domain could not be contacted” there could be a few different causes for this issue. Most likely, there aren’t any shenanigans happening, which makes this blog different from my usual writing. Users that can’t contact the Domain Controller are most likely having network or hardware issues. A good hacker wouldn’t want to call that kind of attention to their activity –  unless they want to try to steal an administrator login ticket… anyway, this is most likely an easy fix.

    In this blog, we will go through the troubleshooting steps and fixes to resolve the “DC can’t be contacted” issue in Windows.

    Check If Your Computer Has the Correct IP Address

    Step one to troubleshoot the “unreachable DC” issue is to verify that the client has a valid IP address for the network.

    The Windows command to print the current IP address and other relevant information is “ipconfig –all.” The output will look like this:

    First, verify the IP address, does it look correct? If not, reboot the client to get a new IP address and refresh the network stack. If that doesn’t work you might have to go down the hardware rabbit hole, cause not being able to get a DHCP address could be a cable issue or a network card issue.

    Once you have the IP address issues squared away, check that the client can ping the DC. From the command prompt enter “ping domain.com” where the domain is the domain you are trying to check.

    You can also use the “tracert domain.com” command to see all the hops between the client and the DC – it should be very quick.

    If the DC isn’t reachable from the client, and other clients don’t have the same problem, there could be a bad cable or hardware issue on the client or some device in between. Try a different network jack or use wireless to narrow down the problem.

    You can use PowerShell to get the same results with different commands.

    Display IP address: Get-NetIPConfiguration –All

    Ping the DC: Test-NetConnection domainname

    Trace the routes to the DC: Test-NetConnection –TraceRoute domainname

    If none of those things work, it could be a configuration issue on the network (DC, DNS) that you need to check – keep reading.

    Check If the DNS Zone of the Domain Controller Has an SRV Record

    If you made it this far down in the troubleshooting of the “unreachable DC” issue, then you might need to fix your DNS configuration.

    In DNS, there is a thing called an SRV record that defines specific services. The SRV record we need is the pointer to the DC, which lives in the Forward Lookup Zone -> domain -> _tcp folder. The entry is named _ldap.Here are a few commands you can run to retrieve this SRV record if you prefer that to the DNS Configuration GUI.

    From the cmd prompt on the DC:

    nslookup set type=all

    ldap._tcp.dc.msdcs.your_domain_name.com

    You should see the name of your DC in the output.

    You can also run the following PowerShell to see the same output from any machine on the network here.

    If you get a name that isn’t a proper DC, that explains why you are getting the “unreachable DC” error. The system is looking for the DC on the wrong computer. Update this SRV record to point to the correct computer.

    If the name is correct, click Details for troubleshooting information.

    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:

    Check Ping status

    Add domain controller IP in DNS list

    Don’t use Public DNS

    Start DNS Client service

    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.
