asp.net Website can't connect to SQL server - login error

Question

out of the blue i am getting intermittent error from my website saying:

A connection was successfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)"}

any suggestion on what might be wrong? seems like the connection to the db can't be established but i don't understand why it would be complaining about the login process

Answer 1

Please try following and let me know if you find it useful.

1. Login with windows authentication.
2. Right click on the Instance name - Server Properties
3. Security page
4. Set the Server Authentication - 'SQL Server and Windows Authentication mode'

Then close the sqlserver and restart. It should work.

if the above steps donot work then try thebelow ones: Make sure the user is not disabled 1. Login as an Administrator into the SqL Server
