How To Fix Dns Server Error Windows 7

[Nichol Sadlon]

This problem may occur if there's a duplicate entry for the specified configuration section setting at a higher level in the configuration hierarchy (for example, ApplicationHost.config or Web.config file in a parent site or folder). The error message itself points out the location of the duplicate entries.


Examine the specified configuration file, and compare it with its parent ApplicationHost.config or Web.config file to check for duplicate entries, as suggested by the error message. Either remove the duplicate entry, or make the entry unique. For example, this problem may occur because the ApplicationHost.config file has a duplicate entry for the following code:

Cannot connect the computer to the server because either another software installation is in progress or, the computer has a restart pending. Either complete the installation process, or, restart the computer and try to connect it again.


Note This problem may continue to occur even after you restart the computer multiple times.



Note This issue occurs on the client computer when connecting to the server in the Applied To section. The resolution steps should be performed on the client computer.






I'm trying to install a dotnet core application in IIS on a machine with windows server 2012 R2 installed, but I'm getting Error 500.19 with the following characteristics:


You get this error message when a connection attempt is rejected because of an authentication failure. User logins can fail for many reasons, such as invalid credentials, password expiration, and enabling the wrong authentication mode. In many cases, error codes include descriptions.


A double-hop typically involves delegation of user credentials across multiple remote computers. For example, assume you have a SQL Server instance named SQL1 where you created a linked server for a remote SQL Server named SQL2. In linked server security configuration, you selected the option Be made using the login's current security context. When using this configuration, if you execute a linked server query on SQL1 from a remote client computer named Client1, the windows credentials will first have to hop from Client1 to SQL1 and then from SQL1 to SQL2 (hence, it's called a double-hop). For more information, see Understanding Kerberos Double Hop and Kerberos Constrained Delegation Overview


This error occurs when a user tries unsuccessfully to log in. This error might occur if your computer isn't connected to the network. For example, you may receive an error message that resembles the following one:


Check the event logs on the client and the server for any network-related or Active Directory-related messages that were logged around the time of the failure. If you find any, work with your domain administrator to fix the issues.


To increase security, the error message that is returned to the client deliberately hides the nature of the authentication error. However, in the SQL Server error log, a corresponding error contains an error state that maps to an authentication failure condition. Compare the error state to the following list to determine the reason for the login failure.






When the server is configured for mixed mode authentication, and an ODBC connection uses the TCP protocol, and the connection doesn't explicitly specify that the connection should use a trusted connection.


When SQL Server is installed using Windows Authentication mode and is later changed to SQL Server and Windows Authentication mode, the sa login is initially disabled. This causes the state 7 error: "Login failed for user 'sa'." To enable the sa login, see Change Server Authentication Mode.


So basically I am using anaconda prompt to launch the jupyter notebook on Windows 10.It works but I can't navigate for long in the jupyter "explorer" because very quickly it can't find directories and it shows: server error: error.


For some reasons I moved this folder : (Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL) to another drive, then returned it to the same location, but sql server has stopped working, showing this error when trying to start it again:


Windows could not start the SQL Server (MSSQLSERVER) on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 3417.


Note that this will reset SQL server to its defaults, so you will have to hope that you can restore the master database from E:\backup\master.bak. I couldn't find this file, so attached the existing databases (by browsing to the existing .mdf files), and everything was back to normal.


2018-06-19 20:41:52.20 spid12s TDSSNIClient initialization failed with error 0x271d, status code 0xa. Reason: Unable to initialize the TCP/IP listener. An attempt was made to access a socket in a way forbidden by its access permissions.


The master database records all the system-level information for a SQL Server system. This includes instance-wide metadata such as logon accounts, endpoints, linked servers, and system configuration settings. In SQL Server, system objects are no longer stored in the master database; instead, they are stored in the Resource database. Also, master is the database that records the existence of all other databases and the location of those database files and records the initialization information for SQL Server. Therefore, SQL Server cannot start if the master database is unavailable MSDN Master DB so you need to reconfigure all settings after restoring master db


I copied a master.mdf und mastlog.ldf from another Computer (luckily, we have a lot of Clients with the same configuration, otherwise template data would be perhaps necessary). I backed up the damaged master.mdf and mastlog.mdf. After that I replaced the bad ones with the ones from another Computer. And it worked. I needed to start the MSSQLSERVER Service of course. But, after that I had Problem that the user was already existing but orphaned (error code 15023), I executed the query


I encountered this issue after changing database location. And I solved it by moving system databases back to their default locations. Although I will recommend not to move system databases like master and model to some other location. But if you want then you can refer to this article: -us/sql/relational-databases/databases/move-system-databases?view=sql-server-2017


Example: If for some reasons you have moved this folder (Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL) to another location then returned it to the same location. So, though it was returned to the same location the server may stop working and show error code 3417 when trying to start it again.


In my case problem was about evaluation period expiration. I also went through this thread of StackOverFlow.You can investigate your problem by going to Event Viewer --> Windows Log (Application) and then search for your error id. For Step by Step guide to view error id in event viewer visit this...


Mohammed ShahedI know this thread is pretty old but I'm hoping that this may help someone. I had the same error on Windows Server 2008 R2 activation. Plus I had many other certificate errors when browsing websites. The solution was download the Microsoft update for the Windows Root Certificate Program.


The Windows activation error code 0x80072f8f usually occurs while updating, when the computer is trying to connect to the online activation service, or when the product key is not verified during activation. When the error appears during Windows installation, it could indicate that the computer settings were found invalid during the verification.


I am trying to build a windows based container and i get the same error. It seems to be an issue with latest release, i have installed 10/31 release and it works fine. For some reason docker engine is not showing up in the windows services with the latest release. After trying multiple things , i finally gave up and installed 10/31 release and everything works. hope this helps someone


I am facing an issue accessing my WD MYCloud Home for the past 5 days. I enabled my local user for my network and i was able to see and access my files on both Windows and Mac devices inside my house. For the past 5 days it stopped and shows me the attached error. I tired to login to turn off the local sharing and enable it again but I am getting another error:


Thank you for the update and never mind about the reset of MCH as this server error is most likely caused by a Samba error from the My Cloud Home which requires an update of the firmware from WDC.


I am affected by this issue after our NextCloud server was updated from samba 4.11.3 to samba 4.12.3 (using the samba-heimdal AUR workaround for the broken Archlinux samba 4.12.3 package). Applying the patch #20622 (comment)

gives us back the SMB external storages. Deleting/recreating the shares was not neessary.


Are You the Web Manager? See Fixing 500 Internal Server Error Problems on Your Own Site towards the bottom of the page for some better advice if you're seeing the error on one or more of your pages.


5xx server errors on Instagram (from 500 to 511) indicate a problem with Instagram's servers. The best course of action is to wait for the problem to be fixed, but you can also try a few things yourself. Double-check your connection, try logging out and back in again, or reinstall the app or check for app updates.


If you see Hulu 500 error, it's most likely a problem with the website and maybe a problem with the stream. Refresh the web page and try again. If you're still getting the error, try a different web browser or change to a different streaming device. Also, test your internet speed to make sure it's fast and stable.


There are a variety of reasons these types of DNS errors can occur. Fortunately, most of them have simple resolutions. In fact, fixing the issue could be as easy as restarting your computer or changing web browsers.
