Is SQL Server running? Can you connect to that instance of SQL Server? Is SQL Server configured to allow connections correctly?

You have a communication issue with your server. Here is a great posting that explains how to diagnose and fix it (and don't miss the tool near the end that helps in the diagnosis process):

Solution 2

First and foremost make sure that the SQL Server services are running. Other reasons could be, incorrect connection string or some Firewall blockage.

Here, have a look at this blog post to troubleshoot the issue : MSDN Blogs: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified[^]

If needed, look at these one:
Exception - error 26 - Error Locating Server Instance Specified[^]
provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance...[^]
"Specified SQL server not found" o..[^]
