SQL server error 1326 – How to fix

by | Feb 8, 2021

Stuck with SQL server error 1326? We can help you.

Often SQL server error 1326 pops up when we connect to the SQL server.

Usually, this happens when the IIS Service does not have any rights to use the named pipe.

Here at Bobcares, we often receive requests to solve such SQL errors as part of our Server Management Services.

Today let’s see how our Support Engineers fix this error for our customers.

How to fix SQL server error 1326 on Windows 10?

In order to gain access to Windows NT named pipe, the client must be validated by the Windows NT server

Before going to the steps to fix this error, we will do the basic troubleshooting steps given below:

  • Checking whether named pipe/TCP enabled or not.
  • Remote connections allowed or not.
  • Checking if Windows Firewall is off.
  • Ensuring that there is ping the SQL Server box.
  • Verifying that the SQL Services are running.
  • Checking the port number which the SQL Server is using.

Now let’s see some of the methods that are used by our Support Engineers to fix this:

1. Creating an exception for port 1433 in Windows firewall.

The steps to follow are given below:

1. First, go to Control Panel and click on Windows Firewall

2. From there go to the exception tab.

2. Then we click on Add Port and enter the port number and name.

3. Here we can see the SQL name in the exception tab list.

4. Finally click on the OK button.

2. Enabling mixed authentication.

If we are using the SQL Server Authentication we can enable the mixed authentication for fixing this error.

The steps to follow are given below:

1. First, go to the Properties, then take the Security page under the Server authentication section.

2. Then we will choose the SQL Server and Windows Authentication mode radio button.

3. Finally, we will restart the service.

This will fix the error being faced.

( Or )

1. First, go to Run and give services.msc
