Topic: Error of establishment of connection with a SQL Server at object button click "Login"
Kind time of days, !
Started to try to do the web application under ASP.NET. Created 1 form added some objects, launched to check up - all is loaded, added an element "Login". There was an error - after login and password input, and button click "to Fulfil an input" (all is object elements "Login") to me instead of discovery of new page produces an error (more in detail in a picture):
"At establishment of connection with a SQL Server there was an error connected to a network or with a certain copy. The server is not found or inaccessible. Be convinced that the instance name is specified correctly and that on a SQL Server remote connections are resolved. (provider: SQL Network Interfaces, error: 26 - an error at detection of the specified server or a copy)"
Database to the project generally yet did not connect.
Prompt please in what here business and as it can be corrected.
