can't connect to SQLEXPRESS locally

I have SQLEXPRESS installed on a Windows 2003 Server. The SQL Tools show that TCP and Named Pipes are Enabled. I can't connect using either the command line or the Mgmt Studio with either of these protocols.

Following is excerpt from program I'm trying to install:

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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

And this from the command line

C:\Documents and Settings\edulog>sqlcmd -E -S localhost
HResult 0x274D, Level 16, State 1
TCP Provider: No connection could be made because the target machine actively re
fused it.

Sqlcmd: Error: Microsoft SQL Native Client : An error has occurred while establi
shing a connection to the server. When connecting to SQL Server 2005, this failu
re may be caused by the fact that under the default settings SQL Server does not
allow remote connections..
Sqlcmd: Error: Microsoft SQL Native Client : Login timeout expired.

Thanks,

That's expected. Enable shared memory and you'll be good to go.

|||The MS documentation ( in the SQL Server Express Readme) says shared memory is enabled by default. I am trying to connect locally, and have named pipes, and tcp enabled as well as shared memory. All 3 methods fail.

Can't connect to SQL Server Express 2005 using localhost in the connection string.

However it works perfectly if I specify the full server name like this
192-55-55-55\SQLEXPRESS.
Is there any way to configure it so I would be able to connect to it using
localhost?
Thank you,
VladTry using . (dot) as in .\SQLEXPRESS. localhost may or may not be
configured.

The idea is to avoid using a server instance name. Just an IP address.

Cant connect to SQL Server 2005 in Visual Studio, only SQLExpress works?

Hi all,

I'm having a big problem here. I can't seem to connect to a database of MSSQL Server 2005... Here is what I've did:

1. Under the Server Explorer>Data Connections. Right click and choose "Add Connection..."

2. Data Source was "Microsoft SQL Server Database File". Click OK.

3. I browse to the database in the MSSQL.2/MSSQL/Data folder.

4. Click on the "Advanced" button, and change the default DataSource from .\SQLEXPRESS to .\MSSQLSERVER. Click OK

5. Received this 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 setting SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid)

Only .\SQEXPRESS that I was able to connect to... i've tried the solution from Microsoft, opened SQL Server 2005 Surface Area Configuration and enabled "Local and remote connections", checked the option "Using both TCP/IP and named pipes" but it didn't help. This is frustrating because I can't get the Membership provider, login to work on my host. Please help.

Thank you very much,

Kenny.

Hi Kenny,

xuanvu:

Click on the "Advanced" button, and change the default DataSource from .\SQLEXPRESS to .\MSSQLSERVER. Click OK

is there named instance MSSQLSERVER on your host/machine

xuanvu:

Data Source was "Microsoft SQL Server Database File". Click OK.

wondering what did you chose while creating connection for SQLExpress was it Sql Server Database file or SQL Server. could you try to use SQL Server option for .\MSSQLServer?

thanks,

satish.

Yeap the problem lies in the SQL Server instance name... I was able to connect to the database now, but here is the problem that I've been battled for a whole week without success... Reading countless forum for a solution but none seems to work.

Here is the problem that I've posted: http://forums.asp.net/t/1131239.aspx

Thanks,

Can't connect to sql server 2005 - SSL

Hi,
I Receive this message when I try to connect sql server 2005 express...
Cannot connect to LOCAL\SQLEXPRESS.
===================================
A connection was successfully established with the server, but then an error
occurred during the pre-login handshake. (provider: SSL Provider, error: 0 -
La cha?ne de certificat a été fournie par une autorité qui n'est pas
approuvée.) (.Net SqlClient Data Provider)
I don't have a SSL certificate and i don't want to use it.
Do you have any idea how I can fix it ?
Thanks in advance.

Forget it...
I found the solution. I ran REGEDIT and remove the
HKLM/SOFTWARE/MICROSOFT/MSSQLServer/CLIENT/...
... and there were a key about SSL (I already forgot the name).
After that, SQL SERVER ran without error.

Hello guys,

I've got some troubles , by attempting to connect the SQL Server database to my server.

I've got this error message on the SQL Configuration Manager (when i tried to start SQL Server which was stopped) " The request failed or the service did not respond in a timely fashion.Consult the event log or the other applicable error logs for details "

I'm on it since this morning and i haven't been able to fix it , none of the web ressources helped me you're my last chance of sleeping tightly :'(

Thank you so much.

Amokrane CHENTIR

welcome to the forums,

after reading the logfile, i think the Master database is damaged , note that SQL server can't work wothout this database .

you need to re-install the Sqlserver , or repair the installation , go to add/remove programs from control panel ,

and repair the SQl server Express Installation.

Thank you very much , i've just tried it and it worked :)

Can''t connect in Sql Express on local machine

I have SQL Express running on my laptop but are unable to connect to the default database paulm-laptop\sqlexpress

When I try to connect I get the error message

TITLE: Microsoft SQL Server Management Studio Express
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

Everything is on my laptop whcih is running Vista Business as an administrator

Any ideas why,

Thanks Paul

Did you enable remote connections for your SQL Server Instance ? If not, have a look at my screencast for more information how to do this.

Since you are on Vista, you should make sure that you are running Managment Studio as Administrator (right click on the shortcut and on Compatibility, choose Run as Administrator) or you can just right click on the shortcut and choose Run as Administrator each time you run it. I have seen this error when running it without it.
