Error 40 , could not open a sql connection

I have recently bought Kaspersky Internet Security 2014. Before the installation of Kaspersky, SqlServer 2008 R2 express edition was working without any error. But after it's installation I got error saying:
" A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.
(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)".
Please help me to get out of this. I have checked all the ports, TCP/IP enabled, SqlServer borwser services.

Ya, Kaspersky was not the problem. I was connecting to wrong instance. Before, i used to connect with
"Data Source=MANCHANA123\SQLEXPRESS;Initial Catalog=Musicworld;Integrated Security=True".
And it was working fine.
Currently, it is not working with same command, I need to make change like this..
Data Source=MANCHANA123\\SQLEXPRESS;Initial Catalog=Musicworld;Integrated Security=True
Use of "\\" instead of "\" .AND now i have no problem here.
Thank you so much Shanky_621 for answering me..

Could not open odmuserId.sql

HI,
I'm a new comer in odm.
I have problem when i try to configure oracle data miner 10g in my oracle db 10g.
I follow the configuration instruction from oracle data miner tutorial.
But when i execute:
SQL><MY_ORACLE_HOME>/dm/admin/odmuserId.sql <MY_ODM_USER> <MY_ODM_USER_PASSWD> <MY_ORACLE_HOME> /tmp/
in sqlplus then i've got this error message "Could not open odmuserId.sql"
could anyone help me,please..
Note:
i used
RH AS4
oracle db 10.1.3

Could you cd to $ORACLE_HOME/dm/admin and check whether you have all the DM files? odmuserld.sql should be there if installation is correct.
Also make sure use @ sign in front of the script at SQL prompt.

Named Pipes provider, error:40 could not open a connection to sql server. Only happens on one of the front end SRS servers

when testing a datasource connection I get the following error.
Named Pipes provider, error:40 could not open a connection to sql server.
I've read all the posts on this and nothing works. This is a scale out deployment and the connection
works from the other server I have setup with SRS that is connected to the same backend SRS databases. It just doesn't work from one of the SRS front ends. I'm at a loss.. please help

Enable both named pipe and TCP communications.
Make sure client is using the same (named) pipe name as server for connection.

Reporting Services 2008 R2 configuration error: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

Hi, I am using SQL Server 2008 R2 and on one of our dev boxes I am trying to setup ReportServer using ReportingServices Configuration manager. This is was installed longtime back and during installation they created a service account for reporting services.
When I try to configure the service account I do not get the service account created during the installation in the pull down and if I were to use something different I get this "Named Pipes Provider, error: 40 - Could not open a connection to SQL Server"
error.
Thanks in advance...........

Re: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

Hi,
I'm encountering an issue with "Named Pipes Provider, error: 40 windows" and am having problems determining how to fix it due to the environment I'm using. I have two SQL Servers installed on two separate Win2K3 Server boxes, one is SQL Server 2000 and the other is SQL Server 2005. The SQL Server 2000 contains the actual application data. The 2005 database is used only for Reporting Services. I've set up the reports on SSRS such that their datasources hit the 2000 server. This is using SQL Server authentication.
When testing the reports via SSRS (in Visual Studio 2005), the connection to the data works and the reports are generated fine. When I deploy them to the reporting server and launch IE to test locally (still on the 2005 box), I get this "Named Pipes Provider, error 40" issue. I made sure that Named Pipes and TCP were enabled and the port set at 1433 (to match that on the 2000 box).
Now I changed the datasource's authentication from SQL Server to Windows authentication. I tested this in SSRS and this works too. When I redeployed the reports with this authentication change, testing the reports via IE locally (on the 2005 box) worked. Great. Now when I open IE on an external box, i.e. on the 2000 box, and try to test the reports, I get this same error 40 issue. I've been through a few threads describing the error 40, fiddling around with the SQL Server configuration as well as SSRS, to no avail. I have a feeling this error 40 issue has to due with permissions/authentication between the SQL Server boxes but I can't really be sure. Anyone have any ideas on how to troubleshoot my situation. Thanks.

Named Pipes Provider, error: 40 - Could not open a connection to SQL Server :
I. Incorrect connection string, such as using SqlExpress.
Check out: http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=558456&SiteID=17
https://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1245564&SiteID=1
The typical error when dealing with Express includes:
a. User is not aware of SqlExpress was installed as a named instance, consequently, in his/her connection string, he/she only specify ".","localhost" etc instead of ".\SqlExpress" or "<machinename>\Sqlexpress".
b. Np was disabld by default after installing SqlExpress.
c. If Sqlexpress was installed on the remote box, you need to enable remote connection for Express.
Please read the following blog for best practice of connecting to SqlExpress.
http://blogs.msdn.com/sql_protocols/archive/2006/03/23/558651.aspx
II. Named Pipes(NP) was not enabled on the SQL instance.
Check out: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=136253&SiteID=1
Oppose to SQL 2000 which turn on all protocols, SQL 2005 SKUs turn off NP by default. So, when you see this error, please check:
1) Go to SQL Server Configuration Manager, See Server has NP enabled.
2) %windir%\program files\microsoft sql server\mssql.1\mssql\log, notepad ERRORLOG, see whether Server is listening on NP. You should see "Server named pipe provider is ready to accept connection on [ \\.\pipe\sql\query ] or [\\.\pipe\mssql$<InstanceName>\sql\query]"
3) Notice that "sql\query" is the default pipe name, so you need to know server is listening on which pipe name. eg: if you specify server pipe name is "sql\query1", then you would see in the errorlog that server listening on [ \\.\pipe\sql\query1 ], and go to SQL Server Configuration Manager, click client Named Pipe properties, see whether the pipe name is same with the one server listening on.
4) If you are using SQL Native Client ODBC/OLEDB provider({SQL Native Client} or SQLNCLI), go to SQL Configuration Manager, click client protocols, make sure NP and TCP are both enabled. Right click properties of NP, make sure client is using the same pipe name as server for connection.
5) If you are using MDAC ODBC/OLEDB({SQL Server} or SQLOLEDB) provider, in command line, launch "cliconfg.exe" and make sure NP enabled and right pipe name specified.
III. Remote connection was not enabled.
Check out: when you right click on the Server in SQL Server Management Studio, in Connections, the Remote server connections part, you have enabled the "Allow remote connections to this server" check box

If you are making a remote connection, namely, your target SQL Server is on the different box as client application, you might need to check whether:
a. "File and Printer Sharing" was opened in Firewall exception list.
b. Please see the blog for enabling remote connection for express and troubleshooting tips of remote connection.

Check out: Open SQL Server Surface Area Configuration and ensure all the required services are started, Remote Connections are configured.
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=348662&SiteID=1
a. use "sc query mssqlserver" for default instance or "sc query mssql$<instancename>" to make sure SQL Server was started. Sometimes, reseason behind the broken of your client application w/ this error:40 might be SQL server restarted and failed, so, it'd better for you to double check.
b. User specified wrong server in their connection string, as described in the forum discussion, "MSSQLSERVER" is an invalid instance name. Remember, when you connect to default instance, <machinename> could be best representitive for the instance, when you connect to a named instance such as sqlexpress, you should specify <machinename>\<instancename> as data source in your connection string.
V. Other reasons such as incorrect security context.
Check out: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=192622&SiteID=1
Such error also occured during user operation such as moving database or db mirroring or cluster, any DB OP that might invovle different sql instances, namely, the destination database is located in another sql instance and user is not aware of the state of the destination. I recommend you first isolate whether this fail is during connection stage or data operation stage.
a. During data operation, you are normally asked to type in the destination server name whether it is default to "(local)" or another server "<remotemachinename>". So, remember the exact string that represent the target instance, then when the error repros, open command line, use "sqlcmd -S<representitive> -E" ,see what happens, if the connection fail, please follow up above I - IV troubleshooting lists. otherwise continue.
b. If you can make basic conection, but still face the error, then there must be something that server reject the connection or client close the connection for some reason.
VI. Please try basic connectivity tests between the two mahcines you are working on. One simple way to verifty connectivity is to use command line tools, such as osql.exe. For example, osql -E -Stcpervername\instancename. If it connects cross-machine successfully, please also verify that your connection string in your scenario is correct.
Here are some blogs which could be helpful: just follow the basic connectivity troubleshooting guidelines on the SQL Protocols blog, see:

Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

This was originally posted in the SSIS Forum, but a member of the IS team suggested it be moved here. "Most recently I got this error (Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) so does this mean that SQL Server is still trying to use named pipes even if I only have TCP/IP enabled in SQL Server Configuration Manager?"
I'm having the same issue, and here's our scenario:
Installed SQL Server 2005 Developer Edition on a machine with WinXP SP2 and enabled remote connections over TCP/IP
Installed SQL Server 2005 Standard Edition on a machine with Win2003 SP1 (remote connections over TCP/IP enabled by default)
Attempted to 'Copy Database' from Developer Edition TO Standard Edition using 'Detach and Attach' method and recieved the error on the Win2003 machine: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
Attempted to 'Copy Database' from Developer Edition TO Standard Edition using 'SQL Management Objects' method and recieved the error on the Win2003 machine: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
Reinstalled Standard Edition on the Win2003 SP1 machine
Checked all the settings on both machines several times, restarted services etc., and read every post I could find referencing the error.
Same error
Lost my last hair
Thanks in advance,
Steve

Nan,
Before I get on with this post - thank you for your reply.
The XPSP2 machine actually had the firewall disabled, and I verified that it could accept connections on the the associated ports with the Shields Up utility. I tested this on both machines.
I can connect to the server from the XPSP2 machine, Import / Export, manage, view logs, and do everything EXCEPT get the Copy Database package to run. SQL Server Agent always fails on the last step with the following error:

HELP ME!!!! itunes wont open, error says could not open key......

I attempted to update itunes to the newest upgrade, and the upgrade was unsucceful, and now this error comes up everytime i try to open itunes (it wont open at all). the error says
Could not open key:
HKEYLOCALMACHINE\Software\Classes\.wav\OpenWithList\iTunes.exe.
Verify that you have sufficent access to that key, or contact your support personnel.
This makes no sense since this is on my home PC

hmmm. okay, if you're currently just getting the "itunes has encountered an error ..." let's try the following technique.
preliminaries
download and save a fresh copy of the itunes 6.0.1.3 installer to your hard drive. (eventually we're going to run the install from there rather than online.)
iTunes 6.0.1.3 Installer
switch off any antivirus and antispyware applications prior to any uninstalls, installs or repair installs.
uninstall
use the complete uninstall instructions given in the following document to remove your existing itunes and quicktime:
Troubleshooting iTunes, iPod Software, and QuickTime installation on Windows
... and if you run into problems on the uninstall, try using the Installer Cleanup utility:
Description of the Windows Installer CleanUp Utility
reboot after uninstalling.
reinstall
remember to switch off your antivirus and antispyware.
reinstall itunes using the 6.0.1.3 installer you downloaded previously.
if you get the "itunes has encountered a problem ..." error message again after that install, first check to see if your Quicktime will launch. if you get an error message when you try to launch quicktime, try using the following technique:
iTunes 6 for Windows unexpectedly quits when opened

Error 1402: Could not open key: HKEY_LOCAL_MACHINE... During Installation

Hello,
When I try to install LabView (v7.1 or v8.0) I get the following error:
"Error 1402: Could not open key:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\LVDB.Application\CLSID. Verify that
you have sufficient access to that key, or contact your support
personnel."
I have full administrator privileges on my computer and I am able to
modify that key manually using the registry editor. When I click the
"Yes" button to continue the installation it will complete but then
when I launch LabView I get the following error:
"The requested feature is unavailable on "localhost"".
Can you help me get LabView up and running?
Thanks,

The Adobe knowledgebase article actually pointed me in the right
direction and I was able to solve the issue. Thanks to all who gave
advise, you guys are the reason these forums work!
The error message was actually coming from the Microsoft Installer, not
from anything related to National Instruments. Also, ironically, what
the message said was spot on with one exception, while I personally had
access to the registry key, the installer didn’t. What I ended up doing
was going into the registry using regedit and setting the permissions
on the key in questions such that “Everyone” had full access. After
that I uninstalled LabView then reinstalled and it worked fine this
time. The step by step follows:
1) Open the registry editor by selecting "Run" from the start menu and then typing in "regedit".
2) Browse through the registry and select the entry mentioned in the error message.
3) Choose "Permissions..." from either the edit menu or by right-clicking on the registry key's parent directory.
4) Click the "Advanced" button to add a new user.
5) Type in "Everyone" as the new user and click OK (it may not be
necessary to give everyone full control but this is what I did and it
worked).
6) Configure the permissions for user "Everyone" to "Full Control"
7) Uninstall LabView (if necessary) and re-install.
Best regards,
-Ben

After removing any program I clear out the registry of left over keys from it. Just something I do. I find I can still miss some. This program Windows XP Manager is very good at finding what I miss, and can also defrag the registry. It will also back up the registry for you also. You might want to take a look at it, where you problem seems to stem from the registry.

Scroll down to Cleaner in the link on XP Manager, it explains what it does in the registry.

I already have installed successfully the Labview 6.i student edition. I tried to uninstall all national application and reinstall the labview 7.0 but same error appear.
My opinion is that the key cannot be opened because it doesn't exist.
What can I do to install the new labview 7.0?

Error message Could not open file....on application server

Hi Experts,
we are using 3.1 production server which has four application servers, after harware upgrdation we are facing connectivity problem with datastage.
daily the infospkoes and abap programs are faling with the message "Could not open file........on application server".
when we trigger manually on one server then it gets success, means we are facing problem with other 3 appliction servers. we do not know how to go about this issue.

Hi,
This is error RSBO214 and can be due to upper/lower case letters within your destination path.
Maybe you have changed the path in transaction SE16?
In case you change the destination manually, you have to make sure that that the directory exists and that the authorizations are set up correctly for the extraction user.
Rgds,
