I developed a school DBMS using ASP.NET and SQL Server, and I tried to transfer to another system then I installed SQL Server 2014. After going on my through my default page inserting my user and pass all that will display is :
Unable to establish connection to database.
Error information:
Microsoft OLE DB Provider for SQL Server (0x80004005)
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
Other possible cause of this problem:
The database cannot be opened, most likely due to incorrect connection settings or insufficient security set on your database folder or file.
Can you please let know what would be issue.
Had this before, follow this guide
TLDR: Change the provider to SQLOLEDB.1

I want to access another SQL Server to import and update data of that server's database through a stored procedure.
For that I created linked server using sp_addlinkedserver.
EXEC sp_addlinkedserver
#server = N'LINKEDSERVER'
,#srvproduct=N''
,#provider=N'SQLOLEDB'
,#datasrc=N'[DB-Instance.cuprxxxlj.ap-xxxxxxx-x.rds.amazonaws.com]';
Then try to access by SQL query
SELECT *
FROM [LINKEDSERVER].[DATABASE].[dbo].[TABLE]
And getting errors like
OLE DB provider "SQLNCLI11" for linked server "LINKEDSERVER" returned message "Login timeout expired".
OLE DB provider "SQLNCLI11" for linked server "LINKEDSERVER" returned message "A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.".
Msg 53, Level 16, State 1, Line 0
Named Pipes Provider: Could not open a connection to SQL Server [53].
I had created database instance on amazon server and another is also on the amazon server and both are publicly accessible but don't know why I'm getting Server is not found or not accessible. Am I missing any server site setting or something else?
Please guide me if I am going in wrong direction.
I found the answer. The problem was an instance, I had created "Amazon RDS for SQL Server" which is currently not supporting to "Linked servers".
So I create a new AWS EC2 instance for Windows Server 2012 R2 and then I create Linked servers in it and tried to assess remotely. Now its working fine as I wanted.
Here is detailed document to Running SQL Server Linked Servers on AWS
Thanks.
Maybe try changing the timeout settings?
sp_configure 'remote query timeout', 0
go
reconfigure with override
go
This article explains in detail how to link one AWS Sql Server to another (https://aws.amazon.com/blogs/apn/running-sql-server-linked-servers-on-aws/). I am not certain what is wrong in your case, but this has a lot of steps that I do not see in your description.
And the one thing that does jump out at me is that you haven't configured any login security/access control. So unless the target server is open to the world, I would guess that you have to add that as a minimum.
complete Crystal Reports noob here.
I am having trouble runing a Crystal report since I changed database servers. essentially I set up the exact opy of our database including users and passwords with only the IP changing. When I change the IP in the report connection I get the following:
Logon failed. Details: ADO Error Code: 0x Source: Microsoft OLE DB
Provider for SQL Server Description: [DBNETLIB][ConnectionOpen
(Connect()).]SQL Server does not exist or access denied. SQL State:
08001 Native Error: Error in File C:\WINDOWS\TEMP\temp_b87d4210-
ce32-4059-8257-c0441088d08a {815D8B1D-1C68-4B65-9CEE-936A1ACFA47B}.rpt:
Unable to connect: incorrect log on parameters.
I have already opened and checked the firewall on the SQL server to make sure it is open and have used a rule we use for other websites to connect. I have also checked the firewall log for any rejections but this is completely empty.
I have checked the SQL server is running for both named pipes and TCP/IP (and default port).
Has anyopne any ideas why this connection is not working?
Thanks for you time. All suggestions greatly appreciated.

I'm having a hell of a time trying to create a linked server to Informix from SSMS. I can't find anything online that is helping me resolve the problem. I have downloaded the Informix Driver, have successful connectivity with the System DSN, successfully tested pulling data use SquirrelSQL and ConnectTestDemo, but when I go to create the Linked Server from SSMS I receive the following error:
"Cannot initialize the data source object of OLE DB provider Ifxoledbc
for linked server 'myServerName'. (Microsoft SQL Server, Error 7303)"
In the Provider properties I have checked Allow Inprocess for Ifxoledbc. I have also disabled the Firewall to rule out any port blocking.
I'm banging my head against the keyboard and any help would be greatly appreciated.
Thanks
When I create a linked server in SQL Server, it causes an error
Cannot create a instance of OLEDB provider SQLNCLI10 for linked server 'linked server name '(microsoft sql server error 7302)
How can I rectify this error?
The OLEDB provider may not properly installed. What you chose is the SQL Server native client. Do you have SSMS installed on server? This should come with sql native client OLE DB.
I would like to share an experience when I faced following error
Cannot create an instance of OLE DB provider "xxx.YYYY" for linked server "test". Error 7302.
I observed this message from a failed SQL Server job. On analysis it is found that Allow Inprocess was not enabled for the provider. When this is enabled, everything worked fine for me.
Server Objects --> Linked Servers --> Providers

Configuring OLE DB Providers for Distributed Queries
I need to create a linked server from SQL Server 2012 to a IBM DB2 (9.x) on AIX. It is a mandatory requirement to create the connection with SSL.
I was trying to use "Microsoft® OLEDB Provider for DB2 v4.0 for Microsoft® SQL Server® 2012" but I was not able to connect to DB2 by the Data Access Tool from MS OLEDB.
Later I installed the IBM DB2 client tools and GSKIT and with this I can connect to DB2 via SSL. With the installation also came the connection provider "IBM OLE DB Provider for DB2". The problem is that I can't create the linked server.
I always get the error message
Cannot create an instance of OLEDB Provider "IBMDADB2.DB2COPY1" for linked Sever "mydb2" (Microsoft SQL Server , Error 7302)
In some discussions was mentioned to use a specific provider string, but in this case the field of the provider string is greyed out.
I just have the options for Product name and Data Source. Is the Data Source == the DB Name of the Connection form the IBM BD2 Client tools? What should I use as Data Source?
Okay i could solve the problem and want to share the solution.
The mentioned provider IBMDADB2.DB2COPY1 comes from the installation of the IBM DB2 Client tools.
In Server Objects --> Linked Servers --> right click new server you can choose the provider. Using the "IBM OLE DB Provider for DB2 - DB2COPY1" which has access to the configured connection including the SSL Keys, the field Data Source is greyed out.
The key to successfully create a linked server to a DB2 is not the guy but the script. There you can use also provider string information even it is greyed out in the GUI.
EXEC master.dbo.sp_addlinkedserver #server = N'MyLinkedServer', #srvproduct=N'IBMDADB2',
#provider=N'IBMDADB2', #provstr= N'HOSTNAME=hosturl;Port=12345;
DATABASE=DBinDB2Client;UID=ItsMe;Pwd=secret;Security=SSL;', #datasrc=N'DBinDB2Client'
Et voila, as you can see the linked server will be created successfully and can acceess the DB2 Database. The issue is solved.

edit:
the linked server can only! used by it's creator. if other users want to access the server, they'll get this error:
Cannot create an instance of OLE DB provider "MSDADASQL" for linked server "MyDB2"
there is a tutorial how to give the permission to other users:
http://blogs.msdn.com/b/dataaccesstechnologies/archive/2011/09/28/troubleshooting-cannot-create-an-instance-of-ole-db-provider.aspx
after you walk through the tutorial, you also need to reboot.
