Help! getting errors when trying to connect to SQL Server Management Studio

Hi All,

I have Windows 2003 Server with MSSQL 2005 Standard.

I am able to connect via Windows Authentication, but when I try to change it to SQL Server Authentication with user 'sa' I'm then being prompted with the error msg:

A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (.Net SqlClient Data Provider)
Here is the entire list of msgs that are showing up:

===================================

Cannot connect to SOLELL-QGL5PG9D.

Hi,

didi you enable mixed authentication or did you just enable the Windows Authentication ?

|||Hi Jens,

I installed the MSSQL a week and a half ago, and I believe it was set to Mixed. I simply don't remember.
Is there a way to know?
Can it be changed to Mixed mode in the event that I missed that? or do I need to uninstall and re-install from scratch?

thanks,

-Alon.
|||Hi Jens,

Since I didn't have any database created yet, I've uninstalled MSSQL and Re-installed it.
This time, I made sure it was set to the Mixed Mode.
I don't know if there was a way to verify an early install or if there is a way to change from
Windows Auth Only to Mixed mode, but Uninstalling and Re-installing took only 30 minutes and I had no databases that I needed to check previously,. so that was my solution.

Thanks for the interest.

Hi,

just for the completion of your answer, the authentication mode can be investigated by using the SQL Server Management Studio and right clicking on the server, choosing the properties and viewing the setting in the Security pane. If you don′t have any visual tool for editing this you can use the registry key

Default instance:
"HKEY_LOCAL_MACHINE\Software\Microsoft\MSSqlserver\MSSqlServer\LoginMode"

to 2 for mixed-mode or 1 for integrated.

Have in mind that changing the setting will need a restart of the server to apply.

|||Hey,

I had this same issue. My MSSQL 2005 server was setup on a port other than the default 1433. Once I added the port number to the connect string, I was able to connect. ie.: SERVERNAME, 9999

Good Luck.
