While connecting to SQL Server 2005, I am getting the following error.
"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (Provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)"
I restarted the Server and then tried to connect to SQL Server, it is allowing me to connect. Whenever the problem comes, I am restarting the server. But I want the actual solution for this problem.
Can anybody help me out in solving this issue.

are you connecting to the local server or remote server?

connecting using windows login/sqlserver login?

Yes, I am connecting to a local server.

Using SQL Server Authentication.

Check if all the Services are running in sql server configuration manager

check the protocols if they are enabled.

You sometimes get the same error, when you have entered a wrong userid/pwd.

hi,

im getting the same error but im using windows authentication - any suggestions? Thanks :o)

no worries, managed to solve it myself. basically i made sure all services were running as previously posted, and then, funnily enough, running SQL Server Management Studio as administrator did the trick!

Thanks anyways :o)

Administrator shouldn't matter, it's the accounts that are set up in SQL Server. Likely the local administrator's group is set up as a login in SQL.

Im not sure what 'instance' means. :unsure:

Please correct what i have done wrong.

Assuming the ff.

name of my computer = HOMELAPTOP

Username= ASHH

Server type: Database Engine

Server Name: HOMELAPTOP/SQLEXPRESS

Authentication: windows authentication

Username: HOMELAPTOP\ASHH

Password: "left blank"

you can check your instance name by looking at the services maybe SQL service

It should be back slash: SQL Server Name\instance

To find instance name:

Click on Start> Programs > MS SQL ..2008 > Configuration Tools > SQL Server C.. Manager > SQL Services and the instance is SQL Server (MSSQLSERVER) so if you didnt make any changes during the instalation MS names it MSSQLSERVER.
