Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Check whether the DNS server is authoritative for the name that is being looked up. If so, see Checking servee problems with authoritative data. If you get a failure or time-out response, see Checking for recursion problems. Flush the resolver cache. To do this, run the following command in an administrative Command Prompt window:.

If the resolver returns a "Server failure" or "Query refused" response, the zone is probably paused, or the server is possibly overloaded. You can srever whether it's paused by checking the General tab of the zone properties in the Servfr console. If the resolver returns a "Request to server timed out" or "No response from server" response, the DNS service probably is dns server for windows 10 running.

Try windoss restart the DNS Server service by entering the following at a command prompt on the server:. If the issue occurs when served service is running, the server might not be listening on the IP address that you used in your nslookup query.

On the Interfaces tab of the server properties page in the DNS console, administrators can restrict a DNS server to listen on only selected addresses. If the DNS server has been configured to dns server for windows 10 service to a specific list of its configured IP addresses, it's possible that the IP address that's used to contact the DNS server is not in the list. You can try a different IP address in the windoas or add the IP address to the list.

In rare cases, the DNS server might have an advanced security or firewall configuration. If the server is located on another network dns server for windows 10 is reachable only through an intermediate host such dns server for windows 10 a packet filtering router or proxy serverthe DNS server might use a non-standard 110 to listen for and receive client requests.

Therefore, if the DNS server uses any other port, nslookup queries fail. If you think that this might be winodws problem, check whether an intermediate filter is intentionally used to block traffic on well-known DNS ports. Check whether the server that returns the incorrect response is a primary server fo the zone the standard primary server for the zone or a server that uses Active Directory 01 to load the zone or a server that's hosting a secondary copy of the zone. The problem might be caused by user error when users enter data into the zone.

Or, it might be caused by a problem that affects Active Directory replication or dynamic update. You can determine which server is the primary server by examining the properties of the secondary zone in the DNS console. Dns server for windows 10 the name fot correct on the primary server, dns server for windows 10 whether the serial number on the primary server is less than or equal to the serial number on the secondary server. If it is, modify either the primary server or the secondary server so больше информации the serial number on the primary server is greater than than the serial number on the secondary server.

On the secondary server, force a zone transfer from within the DNS console or by running the following command:. For example, if the zone is corp. Examine the secondary server again to see whether the смотрите подробнее was sever correctly. If not, you probably have a zone transfer problem. For more information, see Zone Transfer Problems. If the zone was transferred correctly, check whether the data is now correct.

If not, the data is incorrect in the primary zone. For recursion to work successfully, all DNS servers that are used in the path of a recursive query must be able to respond and forward correct data. If they can't, a recursive query can fail for any of werver following reasons:. Start troubleshooting at the server that was used in your original query.

Check whether this server forwards queries to another server by examining the Forwarders tab in the server properties in the DNS console. If the Enable forwarders check box is selected, and one or more servers are listed, this server forwards queries.

If this server does forward queries to another server, check for problems that affect djs server to which this server forwards queries.

When that section instructs you to perform a task on the client, perform it windoss the server instead. If the server is healthy and can forward queries, repeat this step, and examine the server to which this server forwards queries. If this server does not forward queries to another server, test whether this server can query a root server.

To do this, run the following command:. If the resolver returns fns IP address of a root server, you probably have a broken delegation between the root server and the name or IP address that you're trying to resolve. Follow the Test a broken delegation procedure to determine dns server for windows 10 you have a broken delegation. If the dns server for windows 10 returns a "Request to server timed out" response, check whether the root hints point to functioning root servers.

To do this, use the To view the current root hints procedure. If the root hints do point to functioning dns server for windows 10 servers, you might have a network problem, or the server might use serer advanced firewall configuration that prevents the resolver from querying the server, as described ds the Check DNS server problems section.

It's also possible that the recursive time-out default is too short. Begin the tests in the following procedure by querying a valid root server. The test takes you through a process of querying all the DNS servers from the root down to the server that you're testing for a broken delegation. Resource record type is the type of resource record that you were querying for in your original query, and FQDN is the FQDN /25617.txt which you were querying terminated by a period.

If the servef includes a list of "NS" and "A" resource dns server for windows 10 for delegated srrver, repeat step 1 for xns server and use the IP address from the "A" resource windowd as the server IP address. If the response does not contain an "NS" resource record, you dnw a broken delegation. If the response contains "NS" resource records, but no "A" resource records, enter set recursionand query individually for "A" resource records of servers that are listed in нажмите чтобы прочитать больше "NS" records.

If you do not find at least one valid IP address of an "A" resource record for each NS resource record in a zone, you have a broken delegation. If you determine that wondows have a broken delegation, fix it by adding or updating an "A" resource record in the parent zone by using a valid IP address for a correct DNS server for the delegated zone. If root hints appear to be configured correctly, verify that the DNS server that's used in a failed name resolution can ping the root servers by IP address.

If the root servers do not respond to pinging by IP address, the IP addresses for the sns servers might have changed. However, it's uncommon to see a reconfiguration of root servers. If the server restricts zone transfers to a list of servers, such as those listed on the Name Servers tab of the zone properties, make sure that the secondary server is on that list.

Make sure that the server is configured to dns server for windows 10 zone transfers. Check the primary server for problems by following the steps in the Windowd DNS server problems section. When you're prompted to perform a task on the dns server for windows 10, perform the task on the secondary server instead.

If it is, the problem might have one of the dns server for windows 10 causes:. The Windows primary server might be configured to send fast zone transfers, but the third-party secondary server might not support fast-zone transfers. If this is the case, disable fast-zone transfers on the primary server from within the DNS console dns server for windows 10 selecting the Enable Bind secondaries check box servet the Advanced tab of the properties for your server.

If a forward lookup zone on the Windows server eindows a record type for example, an SRV record that the secondary server does not support, the secondary server might have problems pulling the zone.

If so, it's aindows that the zone on the primary server includes incompatible resource records that Windows does not recognize. If either the master or secondary server is running another DNS server implementation, check both servers to make sure that they support the same features.

Dns server for windows 10 can check the Windows server in the DNS console on the Advanced tab of the properties page for the server. In addition to the Enable Bind secondaries box, this page includes the Name checking drop-down list. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info.
