We can address the issues users face when authenticating each of our shared SQL queries with server-side fixes. Some of the possible modes will help the user eliminatebugs by checking and enabling the following options in SQL Configuration Manager as described below:
There are two more SQL servers on the web. All direct calls are made using the TCP / IP process. There is a standard port for installing SQL Server, such as 1433. This port can be changed as needed using SQL Server Configuration Manager. For an accurate SQL Server connection, TCP / IP must be enabled. However, if it can be disabled, do the following:
- Open MS SQL Server on your system.
- Access specialized configuration tools, then open SQL Server Configuration.Manager on your system >> SQL Server Network Configuration.TCP / IP
- Select an option and right-click to activate it.
When the process is complete, restart the SQL server so that the changes are immediately saved.
Shared Memory Protocol is used to connect to SQL Server running on the same system. For the most part it is useless when dealing with a database. Sometimes custom authentication does not work when the shared memory protocol is disabled. It’s easyif you activate several possible steps as described:
- Go to Start -> All Programs -> MS SQL Server -> Configuration Tools -> SQL Server Configuration Manager.
- Select a SQL Server network configuration.
- Then right-click the alternate shared memory and select Enable.
How do I enable TCP IP connection in SQL Configuration Manager?
From the appropriate Start menu, select All Programs> Microsoft SQL Server 2012> Configuration Tools> SQL Server Configuration Manager. Click SQL Server 2012 Services. Expand SQL Server 2012 Networking and select Protocols via MSSQLServer (SQL instance name). Right-click TCP / IP and select Enable.
Named pipe protocols are configured locally for target networks. Some of the memory is used by a process returning to a procedure that passes information to most other processes. Another possibility might be on the same system or on a great networked system. The user encounters an error because the named channels are clogged. To enable them, user can follow the same procedure mentioned above by opening SQL Server Configuration Manager – SQL Server Networking – Named Pipes Protocol -. ‘Activate.
VIA is a virtual adapter, an interface that works with VIA hardware. Even a gamer runs into this when the VIA error might not be enabled on your system. To fix the problem with the error, enable the optionVIA in SQL Server network configuration.
How do I allow SQL Server to accept remote connections?
Log in to your server, click your server and click properties. Go to the Security page and select SQL Server and Windows Authentication Mode for Server Authentication. Then go to the “Connections” page and make sure “Allow remote connections to specific servers” is checked and click “OK”.
Windows Firewall acts as a wall between the main server and your system, providing complete protection against all malicious attacks. However, firewalls have traditionally ignored various ports and services. Even the SQL Server ports are ignored by the firewall. SQL Server ports are started on the system, added to an exception to this rule, and then the firewall filters all vehicles from those ports. By default, SQL Server always depends on port 1433, if a standard port is configured, the new port will be larger until an exception is thrown. This can be done in the next step:
- First enter the control panel into the system.
- Now select Windows Firewall – Change Settings. Click on
- in Exceptions, then Add Port.
- In the window that appears, enter the port number and click the “OK” button.
- Then activate your current SQL.
It also happens that enabling a remote connection is important. If this feature is clearly disabled, then SQL Server is working correctly on your system. However, if your function is enabled, perform the followingnext actions:
- on the server node – select Properties.
- Select the Club option from the tab on the left. Activate the option “Allow connections to this server outside the site”
The above article describes some good solutions for removing SQL Server Authentication Error 233. If the user is currently experiencing an error, they will most likely use a different method, which is sqlbrowser.exe. Another way to avoid this error is to simply locate sqlbrowser.exe on the SQL drive where the server is located. Then copy the sqlbrowser.exe approach and create an idea file exception on the firewall. This helps to fix SQL error 233.
