Deployed Application Isn't Connecting To SQL Server
Jan 30, 2007When deploying my application that uses sql server it doesn't connect to the server.
I checked the connection string & it's ok the server instance is the same.
The computer name isn't the same & i use the .SQLExpress as the data source.
I get an error saying 'sqlserver does not allow remote connections error 26 locating server / instance specified'.
Connecting To SQL Server Express From An ASP Application
Aug 31, 2006I have an ASP application which is currently using a SQL 2000 Database, attaching via SQLOLEDB. I am getting ready to migrate my ASP application to .NET using SQL Server 2005 Express. The only problem, is that I am unable to connect successfully from my ASP applcation to my DB under SQL Express.
I have taken all of the steps that I have read, including the blog by Ming Lu. I still cannot be through.
I have included both the messages that are thrown and comments about the drivers and connection strings.
I have enabled TCP/IP and Named Pipes for SQL 2005 EE. I have also included the executable, port 1433, port 135, etc. in the firewall exceptions.
I have defined the DB in ODBC using both the Native Sql driver and the SQL Driver. Connection authentication is via SQL Server Authentication.
If anyone has any input, I would be grateful.
Error Messages:
Named Pipes Provider: Could not open a connection to SQL Server [53]. - using SQLNCLI - SQL Native Driver

Problems With Connecting To Sql Server 2005 From Java Application, HELP!
May 27, 2007Hello, Everybody.
Help me please with one problem which I'm facing with while deploying java server application on my computer (this java app is jBilling). I have configured it as it was said in docs, I have added environment variable CLASPATH as Microsoft documentation said. I'm using SQL Server JDBC driver 1.2 by Microsoft. The result is that I find this message in log file:
2007-05-27 17:21:41,906 WARN [org.jboss.resource.connectionmanager.JBossManagedConnectionPool] Throwable while attempting to get a new connection: null
org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Failed to register driver for: com.microsoft.jdbc.sqlserver.SQLServerDriver; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: com.microsoft.jdbc.sqlserver.SQLServerDriver))
at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.createManagedConnection(LocalManagedConnectionFactory.java:168)
... and so on.
I have copied sqljdbc.jar to lib folder of the server. That's how I specified connection string:
jdbc:microsoftqlserver://localhost:1434;DatabaseName=Billing;integratedSecurity=false;
Can not think out what to do else. Maybe somebody knows what to do about it?
Many thanks
SQL Server Admin 2014 :: Application Connecting To AG Listener Static IP Address - Not Name
Jul 22, 2015We have a bought in application written in Visual Basic 6 using ADO 2.7 to connect to SQL Server. The application has two connections strings and uses internal logic to determine which of the two connection strings connects to a read-write database. It does something as simple as trying an update that makes no changes to a very small table somewhere.
Previously this application connected to a Mirrored Database hosted on two Windows Server Failover Clusters and SQL Server 2005.For the future the App will be connecting this application to a SQL Server 2014 Availability Group.The Availability Group is made up of four servers, in a cluster, two at one site on Subnet A and the other two at a second site on Subnet B. The Availability Group has been given a Listener with a DNS name of AGLISTEST on port 1433 with two Static IP addresses, one for each subnet.
Our Contractor has configured the Application’s connection strings to connect to the two Static IP addresses assigned to the AG. He is of the opinion that although ADO has zero understanding of an Availability Group, at least one of the Static IP Address will translate to the Availability Group primary server because it is a Cluster Resource and so act like a Cluster IP Address on Windows Server Failover Cluster; i.e. sort of mimicking the previous configuration. This does work and he has demonstrated it, however I can’t find any article that proves to my satisfaction this is intended behavior not something that accidentally works. If it is accidental behavior then that would be something that might stop working at an unexpected point in the future.
All the research I have found relates to connecting to the AG Listener name, and all the multi-subnet issues and Active Directory issues that go with connecting using what is a legacy client.So; the question is, is this translation / redirection of static IP Addresses assigned to an Availability Group listener documented and safe?
Connecting An Application Server To DB Server
Apr 7, 2008 Hi all....
I'm not good t adatabases and never had to install one before, but I have an easy question....
I need to install a big application that needs a database server in the back end to run, I have a box with SQL2005 installed on it and I need to let the server be the database server for this application that will be installed on a seperate box....
How would I be able to point this application to the database server? (in general) do I need to install a SQL client on this server and point it to the SQL2005 server in the back?
Do I need to create a "new database" on the SQL sever and give it a name and credentials then point the application to that database? if that is the case, how would I do it?
Thanks.
Application Not Connecting To DB On Restart Of PC??
Mar 6, 2007Hi,
i am stuck in a strange situation.
I
have successfully built my application setup through InstallSheild 12.
Which first installs SQL Express user define instance as a
pre-requisite and then install my application files. First time when i
run my application (without restarting the pc), it connects
successfully with user define instance.
But as i restart my PC and try to open my application, it is not connecting with database.
i am using the following command line to install SQL Express 2005 user define instance:
"/qn ADDLOCAL=SQL_Engine INSTANCENAME=MyInstance SECURITYMODE=SQL SAPWD="test" AUTOSTART=1"
if
i change Remote connection to "using both TCP/IP and named pipes"
through "SQL Server Surface Area Configuration" and then restart my pc
again. My application connects successfully with Database.
Please
guide me where i am getting wrong in building setup. do i have to add
something in my command line to not get this error

Connecting To Web Database From Desktop Application.
Jun 24, 2007I am thinking of using my web database as the database to use for my program, though not sure how feasible due to connection speeds and having to transfer that info.
what I am using as the connection string is
con.ConnectionString = "Data Source=databse ipadress inserted here; Initial Catalog=databasename here;Integrated Security=True"; with real data obviously inserted into the ip and tables, but when i try and send values there it just hangs and then crashes. I am thinking its not finding the database. Is there something else im to do?
I am using the exact same code as when i use my own machine as the server, and it works great that way, only thing different is the trying to send to the web server.
Connecting To SQL Express Database In C# Application
Mar 8, 2007I'm trying to connect to a sql express database on my local machine, using the following connection string:
SqlConnection thisConnection = new SqlConnection(@"Data Source=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf");
However, I keep getting an error message saying "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."
Why would my application be trying to connect remotely when the database is on my local machine? And how can I fix this problem?
Thanks
Error Connecting To SQL Express DB From ASP.NET 2.0 Web Application.
Sep 28, 2006How do I get rid of this error message when tring to log into my web site user account stored on the default ASP.NET 2.o generated database on my local computer?
Server Error in '/FundACure.org' Application.
Cannot open user default database. Login failed.
Login failed for user 'LANBOYASPNET'.
Where "LANBOY" is the name of my computer. I am logged in as myself "LANBOYKEVIN" My web page is trying to log into the server using the name "ASPNET" which I assume is a standard ASPNET user name.
I thought it was failing because I needed to grant access to this user in the server, so I added the account for the server. Same problem.
So I thought I needed to create this user in my Windows XP user list. When I tried it said "this user already exists" even though it isn't displayed in the list. That is when I realized that it is a standard user established by ASP.NET. It is probably supplied in the C# code through a base class.
So, how do I get this DB to connect? Is the user missing, or is it that my connection string is wrong?
Connecting To Local Database After Application Install
Jan 26, 2007
I have created an application which uses a SQL Express database. The program runs fine on the the computer where I built the app, however when I install the app on another computer I get an error telling me that under default SQL Express does not allow remote connections. The problem is that I dont want a remote connection I want a local connection, the database file is on the commputer. How can do get my application to look for the database on the local machine.
My connection string is:
Data Source=(local)SQLEXPRESS;Initial Catalog="C:DOCUMENTS AND SETTINGSADMINISTRATORPLDAQ.MDF";Integrated Security=True
I have made sure that the file is in the correct directory.
Any help would be greatly appretiated

Can't Connect .Net Application From Windows Server 2003 To Database Server (SQL Server 2000)
Apr 3, 2008Hi,
I am having a problem connecting my .net applications from the application server to the database server. When I run the application from my windows xp (sp2) box it works fine. When I try to connect via SQL Management Studio to the database server from the application server I get the same error.
Here is the error:
System.Data.SqlClient.SqlException: 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Here is the Environment:
App Server:
Windows Server 2003 Standard Edition
Inside Company's Firewall/ Network
Database Server:
Windows Server 2000 Advanced Edition
SQL Server 2000 SP4
Remote Connections to the Server is checked
Enable Protocols: Named Pipes & TCP/IP
TCP/IP Port: 1402 (I don't know why it isn't the default of 1433)
The db server is sitting out side the Company's firewall (don't ask me why). I can access it fine from inside the firewall on my XP box but not from windows server 2003. There is a web server outside the our network that also connects to the db server with no problem and that is running Windows Server 2003 Web Edition.
I can ping the db server from the app server using the IP address.
I tried using the IP address and the port 1402 in my connection string but that didn't work from any machine (XP and Server).
I imagine the issue is somehow related to the company's firewall but why would it only block Windows Server 2003 and not XP?
What do I tell the network admin to change?
Any help would be appreciated.
Thanks,
Oran
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.
Jan 22, 2008My site works fine in VWD2008 express, but I get this error when I try to use it on my live website.
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.
According to this article: http://support.microsoft.com/kb/914277 I am supposed to:
1.
Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
Ok, there is no such program in this folder. The only thing in there is "SQL Server Error and Usage Reporting"...
The other thing I am greatly concerned with is this: All is want is for my webpages to be able to access my database for user authentication. I DO NOT want to grant the internet rights to remote connect to my database.

Dec 10, 2007I get the following error and have been trying to figure out why I keep getting it. Initially, I had placed my project under wwwroot folder and ran it under IIS and it gave this error. Then I moved it to my local C drive and same thing. I am sharing this project with two other co-workers and all our config files and code files are same...they don't get this error but I do. I checked that SQL Server Client Network Utility has TCP/IP and the 'Named Pipes' enabled. I thought maybe I have setting in the Visual Studio 2005 that I'm not aware of that's causing this problem...it can't be the server since my co-workers aren't having this error and can't be anything in the code since all of us are sharing this project through vss. I dont' think using different version of .net framework can create this error. I changed the version from 2.0 to use 1.1x and it gave same error... Any help would be greatly appreciated. Thanks in advance.

SQL Server Management Studio - Connecting To Server Never Connects To Server
Sep 20, 2007I am trying to connect to a sql server 2005 server using either windows auth or sql server auth but I can not. When I click on the connect button to connect to a server it never connects. I can not cancel once I press connect. It never times out after I press connect. I removed all registered servers that were registered previously. I have uninstalled all software that involved sql server (and sql2000) run a registry cleaner(not microsofts), installed the software to a new directory and still I can not connect to the sql2005 server (the only db).
Any ideas?
I am running Windows XP with latest services packs for both windows and sql server. I have visual studio 2005 installed on my machine and I have had sql express installed on it previously.

As a result, how can I solve this problem.

When Connecting To SQL Server 2005, This Failure May Be Caused By The Fact That Under The Default Settings SQL Server Does Not A
Mar 2, 2008My environment:
Home PC
Vista Ultimate
SQL Server Developer 2005
I'm about to go absolutely nuts. I've tried so many things including:
1) Of course making sure Remote connections and both TCP/IP and named pipes are enabled for SQL 2005
2) Verified my connection string works. I even tested it in Enterprise Library using the tool and it connects successfully via windows authentication
3) Made sure of course my logged in user is a member of the administrator group and that my user in SQL 2005 logins has db_owner and full rights to the DB I am connecting to. I also made sure the NT AUTHORITY as well as the 3 sql service users have db_owner rights as well as the adminstrator in the SQL Server logins all have db_owner to the DB
4) Started the SQL Server Browser service, SQL Server DB engine, and SQL Server Agent
5) Made sure my site is setup right in IIS 7. I checked the connection string in there as well as it shows up in IIS7 in one of the sections. Using Windows authentication and it is enabled for my site
6) Tried running the .net site using both localhost (IIS) and also tried using the Visual Studio built-in web server. Both give this message still

Error 26: When Connecting To Local Server With SQL Server 2005 Standard Edition
May 20, 2006Hi,
I've been trying to fix this error for two days! and I really need the advice of the experts please!
Computer XP Professional Service Pack2, SQL Server 2005 and Visual Studio 2005 (both Standard Edition)
ConnectionString:
<connectionStrings>
<add name="MyConnectionDB" connectionString="Data Source=(MyServerSqlServer2005);Initial Catalog=MyDB;User ID=sa;Password=PasswordforSA" providerName="System.Data.SqlClient" />
</connectionStrings>
C# code
string myConnectionString = ConfigurationManager.ConnectionStrings["MyConnectionDB"].ConnectionString;
SqlConnection myConnection = new SqlConnection(myConnectionString);
myConnection.Open();
Here I get the 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 settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"}
What I checked so far:
ServerName and Instance Name OK!
Database, Username and password OK!
SQL Server 2005 Surface Are Configuration - Remote connections using both TCP/IP and Pipe Names OK!
SQL Configuration Manager - Protocolos Enabled (TCP/IP, Pipes, shared) OK!
SQL Server Browse running and active OK!
Am I missing something? I never had this problem with SQL Server 2000 and Visual Studio 2003.
Thanks in advance for any help or suggestion you can give me.

Problems Connecting To SQL Server 2005 SP2 On Windows Server 2008 (both 64bit)
Apr 3, 2008
Hi All,
After I installed sql server 2005 64bit standard edition on Windows Server Enterprise 2008 64bit, I cannot connect to the sql instance using the sql management studio on the same machine!
I verified that:
service is running,
in surface area configuration: remote connections to local and remote are enabled, for TCP/IP and named pipes.
ran the command netstat -avn| findstr 49279 to make sure that the server is listening.
firewall is off, but this does not matter since I'm connecting locally to local instance
I'm using domain controller account to login to sql server / also tried the sa account.
what else can be wrong?
thanks.
Assistance In Connecting A SQL Server Client To SQL Server Sitting In A Shared Environment
Dec 5, 2006Hi,
I need to connect to a SQL server thats running in say abc.trident.com and also sits in a shared environment..
I have couple of questions
1) That SQL server is accessible from my network, yet when I swtich on my enterprise manager I am unable to view that in the list of running SQL servers in the populated list.
Is it because its sitting in a shared environment I am unable to view that?
2) What is the connection striing I should use to connect to the server..When I try to configure a SQL server registrations it normally asks for SQL Server name along with the user authentication
Should I mention fill the Server: field as
abc.trident.com
or
// abc.trident.com/abc.trident.com
to connect to the clustered server.
Can some one tell me the proper connection string if both aforementioned ones are incorrect?
Thanks in Advance
Help Connecting Ole/db Linked Server To Msaccess Database In A Different Machine Than Sql Server Resides
Jun 29, 2007Hi,
I have a msaccess linked server that I use to execute sql 2000 stored procedures from a front end in adp (access data project) format without any problem, if it is used on the same machine where the sql server resides (with any user logged on). In any other machine on the local network where I also need to use it, I get an ole/db error message saying that the microsoft jet database engine can not open the file because it's allready opened exclusivly or because it do not has permissions. I created the linked server with both UNC and normal path with the same result.
Thank's for all the help/clues you can give me.
