Sql Network Interface Error 25

• Error 26 Error Locating Server
• Sql Network Interface Error 25 Connection
• Sql Server Error 17

Apparently, different editions of SQL Server set network protocols differently for security purposes, as you can see from the table below taken from the documentation. In this case, I was in fact using Developer Edition for the MSSQLSERVER2016 named instance, so TCP/IP connections – which would be used for remote connections – was disabled. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 28 - Server doesn't support strong text requested protocol) (Microsoft SQL Server, Error: -1) I have enabled the firewall - that's not it.

I have been having a problem trying to connect to a SQL Server. I have installed the Developer edition on an MS Small Business edition 2003 serverI also installed MS Sql Manager and I was able to create a database and connect to it.

The ASP.NET process account, unless you have set it or changed it, is ASPNET or NETWORK SERVICE depending on operatiing system. It is unlikely you chose this account for access to SQL.

But normally you would get a mdifferent error if that was the problem.Take a look at connectionstrings.com for some possibilities in changing your connection string. You may want to use a standard authentication with SQL user and password rather than rely on a trusted connection.Is your SQL on a different server than the web server? I wouldn't think so but you use the IP address of the SQL server in your connection. You should just need to enable TCP/IP, which you said you've done.Jeff.

Sql Server Error 17

Okay so a lot of people have posted a similar question, however I don't seem to be able to find a solution to my problem in any of them. So this is my situation.Yesterday I was working with my SQL Server Express through SQL Server Management Studio. I close my projects as I've done multiple times before and then this morning when I tried to connect again with the tool is gives me this error:TITLE: Connect to ServerCannot connect to.SQLExpress.ADDITIONAL INFORMATION:A network-related or instance-specific error occurred while establishing a connection to SQL Server.The server was not found or was not accessible.

Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)I think my main question here is if there is a solution to this problem, or if I have to install SQL Server Express all over again?PS: Here are some system stats. I'm working on a Windows 10 machine, and the SQL Server Management Studio version is 2014.
