Connecting to sql server database mdf file without installing sql server on client machine?
I am creating a window application that need to use sql server database. I want to install this application to client machine without installing sql server so that my application can still connect to a database i.e mdf file that i will be providing at client
system.
How can i connect to a database(mdf) on client machine through my window application without installing sql server. ? I dont know is it possible or not.
If possible what will be the connection string in that case. Database need not be used in network.you cant connect and view the internals of mdf file unless it being attached to a sql server instance as a database.
The sql server instance can be installed in any box which is in the same domain and then you can connect from your application to it.

Error connecting to SQL server 2005 from Dreamweaver 8
Hi I have a database in SQL server 2005.I just started using
dreamweaver's server behaviours.When I use the "log in" behaviour I
get the following error.
Microsoft VBScript compilation (0x800A0401)
Expected end of statement
/MyBlog/Connections/connBlog.asp, line 9, column 38
MM_connBlog_STRING = Provider=SQLOLEDB;workstation
id="FAZ-F6EE655890B";integrated security=SSPI;data
source="FAZ-F6EE655890B\SQLEXPRESS";persist security
info=False;initial catalog=MyBlog;
-------------------------------------^
First thing that came to my mind was obviously my database
conn isnot right but when I define a conn using the built in
dreamweaver's dialogue and test it, it says that the test
succeeded.Also in the dialogue for the "login page" it shows the
values of fields from the database, so it is definitely connecting
to the database.So I don't know why am i getting this error.Please
someone help!See if this TechNote helps:
ASP error "VBScript compilation error '800a0401' "
http://www.adobe.com/go/15717
Are you using the ASP VBScript server model?
Try creating a simple recordset that displays all records
from a table and
see if you can get that to work. It's less complex code than
the user
authentication server behavior and might help to isolate the
problem.

I have tried from so many forms. This is so frustrating. Thank for everyone/anyone who wants to help. So this is what happened: I had to uninstall my previous sqlserver 2012(which worked great) for some reason, and I uninstalled everything from that download.
Then I installed the trial edition of sql server 2012 (64 Bit) and It wouldn't connect to the database. (Error mentioned above.) My local DB is COWBOYS. (COWBOYS is also my computer name.) After this, I have tried downloading sqlexpress and sqlserver 64bit
many times and cannot connect to my local DB.
How do I connect to my Local DB?
Also, I think this might help: (When I run sqlserve.exe, which I was able to find in C:\Program Files\Microsoft SQL Server\110\LocalDB\Binn, I get an error: Your SQL server installation is either corrupt or has been tampered with(Error getting
instance ID from name). Please uninstall then re-run setup to correct this problem.
I would happily re install it, if it wasn't my 20th time.
I don't have any remote connections, I don't use username/password, only window authentication. I work mostly on visual studio, but without able to store /retrieve data, I don't know how to survive.
May be the solution is very simple, but I am too frustrated.
Some of the things I have tried:
From a command prompt, enter one of the following commands:
net start "SQL Server Agent (MSSQLSERVER)" OR
net start "SQL Server Agent(instancename)"(for instance)
on my sql configuration, I cannot start anything because there is nothing there to start. I can post more details, if that would help. Also, some more details about the error:

Any one that can help me, I will be greatful. Thank you so much. p.s. please ask me anything if you have any questions.It sounds like there are a couple things going on here. First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance. Once you find this, make sure the service is started.
If not started, try to start it and see if it throws an error. If you get an error, post the error message your hitting. If the service starts, you can then launch SSMS and try to connect. If you have a default instance, you can use the machine
name in the connection dialog. Ex: "COWBOYS" where Cowboys is the machine name. However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format. Ex: COWBOYS\Romo (where Romo
is the instance name you set during install).
You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install. Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

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.
larryNamed 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.

IV. Server not started, or point to not a real server in your connection string.
Check out: Open SQL Server Surface Area Configuration and ensure all the required services are started, Remote Connections are configured.

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:

Hi,
I have been trying to get a very simple WebJob developed and deployed onto Azure with little to no luck. I have a MVC Website which has a common project which handles my Data Access Layer with Entity Framework. I have created a WebJob project
using Visual Studio and added the following lines of code to the Manual Trigger Function
[NoAutomaticTrigger]
public static void ManualTrigger(TextWriter log, int value, [Queue("queue")] out string message)
RitualDBEntities db = new RitualDBEntities();
log.WriteLine("Function is invoked with value={0}", value);
List<Location> locations = db.Locations.ToList();
string msg = string.Empty;
foreach (Location location in locations)
msg += location.Name;
message = msg;
log.WriteLine("Following message will be written on the Queue={0}", message);
In my app.config of my WebJob i have the following connection strings:
<add name="RitualDBEntities" connectionString="metadata=res://*/RitualDBEntities.csdl|res://*/RitualDBEntities.ssdl|res://*/RitualDBEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=ritual-pc\sqlexpress;initial catalog=RitualDB;integrated security=True;persist security info=False;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
<add name="RitualContext" connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=RitualDB;Data Source=ritual-pc\sqlexpress" providerName="System.Data.SqlClient" />
<add name="AzureWebJobsDashboard" connectionString="DefaultEndpointsProtocol=https;AccountName=ritual***;AccountKey=tQAP0gyMYKtWPJeIbsqk2iT2k69gyd1FwcyRf3+5Mc9b9EdYzpj0Dq8X2VHUmF*****"/>

When i test locally (F5 Debugging) the webjob runs successfully and does the loop of the objects returned from the database. When i deploy this Azure the WebJob fails with the following error:

If i remove any of my database code and use just the basic Stub code my webjob will run successfully so i know that my connection strings (outside of the DB ones) are correct. My MVC web application also runs perfectly using the same connection strings
in Azure so i also know that they have also been configured.
I am now lost and need some guidance, so if someone is able to assist me that would be much appreciated.
Thanks
Ritual.Can you try to log the connection string you are using in both cases to make sure they are the same?
Also can you share your site name, either directly or indirectly?
This will help us investigate.
Thanks,

Dear all,
I know that this topic may be a bit old school; but it really make me mad as I tried all solutions i found and it still cant be resolved....please give a hand...
The situation is like this,my company divided different platform as a status of project, like DEV, SIT and UAT. I got a project that require me to upgrade an vs2003 project to vs2005. I upgraded it completely and
successfully, it works fine in development and UAT platform; EXCEPT, the SIT platform.
The situation is very strange that, once I move the source to SIT, it return the following error:
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
but it never happen in either DEV or UAT platform and even do I copy the workable web.config from DEV or UAT platform to SIT, the error still here and unable to resolve it.
I search a lot in the internet by Google, but solution suggested are not suitable or fail in my case. Most answer suggest that "enable remote control", "check fire wall", "check server" etc......But as I can connect well the
DBServer in DEV and UAT properly, I dont think those are the cause(but still, I check them all, and all are enabled properly, except my firewall setting is OFF, so adding port is ignored).
After all the searching and testing, I believed and have reason to believe that, the cause is inside my web.config:
<appSettings>
<!-- User application and configured property settings go here.-->
<!-- Example: <add key="settingName" value="settingValue"/> -->
<clear/>
<add key="Environment" value="UAT v1.31"/>
<add key="DBServer" value="DB_UAT"/>
<add key="cnBPSS.ConnectionString" value="data source=DB_UAT\BPSS;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096;pwd=theloginpwd"/>
<add key="UTBPSSConn.ConnectionString" value="data source=DB_UAT\BPSS;persist security info=False;user id=theloginid;workstation id=RP_UAT;packet size=4096;pwd=theloginpwd"/>
<add key="UTDSBDBConn.ConnectionString" value="workstation id=RP_UAT;packet size=4096;user id=theloginid;data source=DB_UAT\DSBDB;persist security info=False;password=theloginpwd"/>
<add key="cnDSBDB.ConnectionString" value="workstation id=RP_UAT;packet size=4096;user id=theloginid;data source=DB_UAT\DSBDB;persist security info=False;password=theloginpwd"/>
<add key="Timer1.Enabled" value="True"/>
<add key="Timer1.AutoReset" value="True"/>
<add key="cnbpss.ConnectionString" value="data source=DB_UAT\BPSS;password=theloginpwd;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096"/>
<add key="cnbpss1.ConnectionString" value="data source=DB_UAT\BPSS;password=theloginpwd;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096"/>
</appSettings>
</configuration>
I know such kind of setting is old school; But due to this program runs for few years from tons of ppl...I dont dare to modify it unless I am very sure they are the cause.....
May I ask if anyone cna give me some advice and help in this issue please? I already tried for weeks and turning mad....Please I really need some help...
Many thanks.
Ksun ChanChecklist of possible reason of this error
1. Check SQL services are running
2. Check SQL Browser service is running
3. Check remote connections are enabled
4. Network connectivity between database & application servers by TRACERT command
5. Check TCP/IP protocol enabled at SQL server
6. Check talent connectivity – telnet <IP address> <port no on SQL server running>
7. Check UDP port 1434 is open or not on SQL Server
8. Check firewall is running or not Check
9. If firewall running, SQL Server & UDP port must be added in exception in firewall

Hi!
I'm using consume adapter service> sqlbinding > to connect to sql database in order to generate sql schemas.
I'm getting below error:
Connecting to the LOB system has failed.
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:
SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified).
ChristianeHi,
As suggested earlier this seems to be a DTC related issue. It can only occur if the DTC settings are not proper or if firewalls don't allow the default ports to communicate.
Check DTC settings on both SQL and BizTalk Box and also check if MSDTC service is up and running.
Go to Start
à Run
à (type in) Dcomcnfg. You should be inside Component Services MMC.
Expand Component Services
à Computers
à My Computer (right click)
à Properties
à MSDTC tab
à Security Configuration button.
Select the checkboxes as following :
Check the below article from Microsoft Support Team, they have listed all the errors which may come during setting up a new system. They also have your MSDTC error listed.
Resolving the issues you may face during BizTalk Runtime Configuration

Hi all,
I have three central sites with each having a Front End server pool (standard).
Site A and Site B are paired for resiliency. Site C is on its own.
On two of my Front Ends (Site A and Site B), when I click on response group tab i get the following warning on the top of the page:
"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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
I have check out the following articles about dont think they apply to me:
http://unifiedme.co.uk/2014/01/network-related-instance-specific-error-occurred-accessing-lync-control-panel-response-group-tab/
I dont see any Event logs that would direct me to a cause.
Which database it is complaining about? RGSDYN and RGSCONFIG are local databases as it is an standard installation. What could be the possible cause for this issue?
Thanks in advance.My latest change was the addition of Site C.
Going through logs (i must have missed it the first time, with all the noisy EWS errors), i found event ID 31147. I am investigating network issues although I have MPLS running to that location.
Does Lync set up open correct ports on the machine itself? -
Hi All,
I have started receiving this error in the logs for the last 10 days and the Schedules Jobs for the database have stopped running. My MS CRM application is working fine.
Can anyone guide me what could be the problem.

Network related or instance specific error occurred while establishing a connection to sql server
Hi all,
I am getting a SQL error - 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified).
Problem is when a user tries to connect with remote SQL Server
through VPN from Domain, it throws this error, and when the same machine tries to connect with Remote SQL Server through VPN as a standlone machine, it is getting connected.
I checked all the settings but ....... There is no any policies deployed in Active Directory.
Any suggetion?
Rajneesh
Rajneesh Kumar MCITP - SA, MCSE, CNAcheck these
1) Make sure your server name is correct, e.g., no typo on the name.
2) Make sure your instance name is correct and there is actually such an instance on your target machine.
