For a SQL Server administrator, there is nothing worse than encountering an error that makes the database inaccessible. One such error is the SQL Server error 17. In this write-up we will take a closer look at the error and will try to understand why this error occurs and how it affects the users day to day workflow.
So without any further delay, let’s begin by understanding more about the error and further find its solutions for a better database accessibility.
What is SQL Server Error 17? Overview
The SQL Error 17 occurs mainly when the client fails to establish a connection with the SQL Server. There can be various causes leading to this issue. Here we will take a look at a few of them to get a better idea of the reasons:
- The desired SQL Server is not running.
- The server name used is incorrect.
- SQL Server is unreachable.
- The SQL Server port is blocked by firewalls.
With these causes, it becomes impossible for the client to connect to the server and further results in errors like SQL Server Error 17, and SQL Server Error 26. We will now take a look at the solutions that will help the users to resolve the error in a much efficient and simpler way.
How to Resolve Error 17 SQL Server? Top Methods
Now, we will discuss the ways that will help the users to fix the error in a hassle free way allowing the users to establish the connection with the server and access the database without any issue. Moving with the first method, let’s see how it will help the users.
Method 1: Verify Server/Instance Name of SQL Server
One of the causes for the error is an incorrect or misspelled server or instance name. Hence, to resolve the error, it is required to check and verify if the server and instance names used are correct. If not, use the right names and spellings to establish a secure connection with the SQL Server database.
This method will help in case the error has occurred due to an incorrect server or instance name in SQL Server.
Advanced Solution to Deal With the Error Professionally
When SQL Server error 17 occurs, users are mainly unable to access the database, which can further risk the safety of their crucial data. Implementing incorrect methods to resolve the SQL Server error can further lead to possible database corruption or loss of data in the database.
For these situations, users need an expert solution that not only repairs the possible corruption in the database but also helps them to restore the data effectively.
The solution we are suggesting is the SQL Database Recovery Tool, a solution that not only helps to resolve database-related errors, but also to recover any lost or accidentally deleted data from the SQL Server database.
Method 2: Check Protocols and Firewall Settings to Fix the Error
There are situations where the users are not able to establish a connection with the application and come across SQL Server error 17. Furthermore, users might also encounter issues if the Firewall blocks the ports required for making a connection with the database. Hence, to repair the issue caused due to these reasons, we will now check if the required protocols are enabled or not, and also if the ports are blocked by the Firewall.
- To check if the required protocols (TCP/IP) are enabled:
- Go to SQL Server Configuration Manager.
- Next, go to SQL Server Network Configuration.
- Look for Protocols for [Required Instance Name].
- Enable the TCP/IP protocols and then restart the server.
- To check firewall settings:
- Check whether the port 1433(default instance) is open to accept incoming connections to the server.
- Also, ensure that port 1434 is enabled and the SQL Server Browser is running.
With the help of these methods, you will be able to resolve the SQL Server error 17 and further establish a secure connection with the SQL Server database. These methods and solutions will help the database administrators resolve the error conveniently and seamlessly.
Conclusion
With the help of this write-up, we have learned the causes for the SQL Server Error 17 and further discussed the ways to resolve the error. By following these solutions, users can effectively resolve the error and access the database in a much simpler and convenient way.
