Cannot connect to MSSQL2005 (Local) Server?

Hello,

I can't connect to MSSQL2005 Standard when providing (Local) for the "data
source=" property in the connection string.
When setting the computer name instead of (Local) it does connect!

Why I can't connect with (Local)?

Thanks in advanced,
Asaf

You might want to provide a bit more information, such as the connection string you are using and
any error messages that are being generated.

Hello Paul,

The C# Connection string is:

workstation id=TestCOMP;packet size=4096;user id=sa;data
source="(Local)";persist security info=True;initial
catalog=TestDB;password=12345


Error message:

[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access
denied.

Do you actually use quote mark around "(local)", as you showed? In the
connectionString, it should be

....data source=(local);...

Not

....data source="(local)";...

Hello Norman,

I am using only (Local).

I can Login to SQL Server with the "SQL Server management studio" using
(Local) at the "Server Name".

But when I place a "sqlConnection" control on a Windows Form I *can't*
connect to (Local).

Asaf

Is SQL Server configured for SQL Server Authentication? It's possible that it may only be configured
for Windows Authentication.

Hello Paul,

The server is not configured to use only Windows Authentication as I can
login from the "SQL Server Managment studio" using (Local) at the name server.
 
Hi,

I have found the solution.

At SQL Server 2005 configuration manager -> SQL Server 2005 Network
Configuration -> Protocols For MSSQLSERVER.

TCP/IP must be enabled with TCP port 1433

Now I can login from my connection string to (Local) name server.


Regards,
Asaf
 
I had to enable TCP/IP - it's disabled by default. Did that and
verified the port was 1433 and everything worked great for me too.
Thanks!
