Cannot connect to MS SQL 2008 R2 locally or remotely.

When I try to connect to my SQL 2008 I get the following error:
TITLE: Connect to Server
Cannot connect to <machinename>.
ADDITIONAL INFORMATION:
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) (Microsoft SQL Server, Error: 53)
I have a SQL 2000 instance, and a SQL 2008 R2 instance, running on Windows Server 2008 R2. The sql 2000 instance is functioning correctly, as is the management studio. I can connect to other SQL 2008 servers, just not my local one.
Named pipes and TCPIP are both enabled. The SQL Browser service is running, as is the SQL Server service.
Any assistance would be greatly appreciated.

Hello,
Please see the following post:
http://blogs.msdn.com/b/sql_protocols/archive/2007/03/31/named-pipes-provider-error-40-could-not-open-a-connection-to-sql-server.aspx
Error 53 means the instance is not reachable. Since the SQL Server 2008 instance is a named instance, verify the dynamic port is not blocked by Windows firewall. Verify again TCP/IP and Named Pipes are enabled.

Cannot connect to ag-sql-listener from Secondary Server

Greetings,
I have a Azure VM setup with two SQLs SQL1 and SQL2, they run a High Availability setup with SQL-AG-Listener as the listener name.
My problem is currently is that if I have SQL1 as Primary, when I'm logged into SQL2 I can't use the SQL-AG-Listener as target to get the Primary server. However I can do a connection to SQL1 directly.
On the Primary server I can however use the SQL-AG-Listener and will get the local server as expected.
The SQL-AG-Listener works perfectly from outside the local network of Azure.

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) (.Net SqlClient Data Provider)
===================================
I don't know what else I can try and do now. I have run through most of the issue handling as I can, all from Opening all ports to and from both the SQL servers on the domain level. Made sure that named pipes, TCP/IP connections on both SQL servers was enabled.
As I can run towards them from the outside, and can connect to them directly on name from the SQL servers themselves, then I know that they can take remote access.
Any idea on what I might be missing would be welcome.

Yes, I know I had a typo in the above, where the ag-sql-listener was typed wrong.. It was ofcause SQL-AG-Listener.
But it is still a problem. I don't know if there are some DNS things that can be done, as it seems this is a problem from within the same subnet and not from outside.

Failure - Cannot connect to Microsoft SQL Server on localhost

Hi!
I have a sqlserver installation on localhost and I want to connect with sqldeveloper.
I fill connection name, username, password, hostname: localhost port: 1433
and then click on retrieve database.
I get the following error message: "Status: Failure - Cannot connect to Microsoft
SQL Server on localhost"
I don't know the reason. I can use another connection to another ms sql server
and it's no problem, but can't connect to localhost.
I have special signs in my computername, for example a "-". Is this the problem?
How can I solve it?
Thank you
Andreas

I am able to successfully connect to my local SQLEXPRESS instance using the following settings:
Hostname: localhost
Port: 1433/DBName;instance=SQLEXPRESS
Even though I use this to connect, I cannot open a tcp connection to port 1433 via telnet. I believe this goes hand in hand with specifying the instance. As I understand it, there are two ways to specify the port, one is directly, the other is through a named instance (another port is used as a service to look up the correct port). SQL Server 2005 appears to prefer named instances instead of specific ports. When "instance" is specified, the port can actually be any number, the driver apparently ignores it.
The Retrieve database (list) appears to be only for informational purposes. I have to specify the database in the Port field (DBName) regardless of what I have selected in this list.
Hope this helps!
PS: Retrieve database will give that error until instance is specified in my case.

Karl,
Perhaps the TNSNAMES.ORA entry (on your database server) needs a domain suffix (eg TG_SQL_SERVER_S0168SS0068.mycompany.com = )

PeopleTools 8.49 PeopleSoft Database Cannot Connect with MS SQL Server 2005

Folks,
Hello. I am working on PeopleSoft PIA. My system is Windows Server 2003, MS SQL Server Express 2005 Standard, PeopleTools 8.49. I am setting up PeopleSoft Database \PsMpDbInstall\setup.exe and got the errors as follows:
Error: Setup fails to connect to SQL Server. The default settings SQL Server does not allow remote connection.
Then I type in "sqlcmd" in Command Prompt and got the same error as follows:
Name Pipe Provider: Could not open a connection to SQL Server. MS SQL Native Client: the default settings SQL Server does not allow remote connection.
In order to fix SQL Server 2005 remote connection problem, I have done the 3 steps as follows:
Step 1: In SQL Server Surface Area Connection, enable local and remote connection, TCP/IP and Name Pipes, SQL Server browser Startup type "automatic" and status "running".
Step 2: Create exception for SQL Server 2005 and SQL Server browser Service in Windows Firewall.
Step 3: Add the default SQL Server Port 1433 into Windows Firewall.
But the above 3 steps cannot resolve SQL Server Express 2005 remote connection problem. Can any folks help to resolve this problem ?
Thanks.

Folks,
Management Studio can connect with SQL Server 2005 successfully.
I have turned off Windows Server 2003 firewall completely. But "sqlcmd" in Command Prompt still connect with SQL Server 2005 because its remote connection is not allowed.
Is the "not allow remote connection" problem caused by Windows Firewall or SQL Server 2005 itself ?
Thanks.

8.8 Client cannot connect to Windows Server 2008 error -1102

SAP Business On 8.8 on PL 18
This is not the first time I have had this issue with Windows Server 2008.
however everytime the resolution was diffrent. Now this site is causing trouble.
The issue is the client cannot connect. We have the log on window, can see the company list. type on the password and we get a -1102 error.
The client on the Server itself can log on. It is the cleints that cannot.
I checked these below.
1 SQL Native client is installed and ok.
2. Licence server is configured and ok
3. The user has admin access to locl PC
4. The SAP user name and password are correct ( client on server can connect fine )
5. The ports 1433, 30000 and 30001 are open on the server.
6. Through SQL server configuration the named pipes and TCP are enabled.
7. SQL server browser is running
The only things I have not tried are
The Firewall is running on the server and I have not yet stopped it. Will try that tomorrow.
Do you have any other ideas please ?

I have got this working but I am not confidant of the outcome - yet - I really need your expert advise here.
This is what I did. In that order.
1.     As Owen suggested I checked if there was a specified Port for the instance. What I found was TCP Dynamic ports were enabled ( SQL server config manager | network configuration | tcp properties ) and there was no TCP port specified. Assuming ( ai may be wrong) that the system assigns a dynamic port to this instance I set it up so the Dynamic port does not happen and manually specified the Port 1433. Restarted the SQL Service. ( still having the Port 1433 open in the firewall). This did not solve the issue.
2.     With the above setting still on, switched off the firewall. Went to the PC client and SAP can log on now. Now keeping the SAP client running, switched on the Firewall on the server. Log off SAP on PC client and log back in ( with firewall off ). SAP now can log on.
3.     I had to do the above step for all PCs to get them working.
4. Currently the firewall is on and clients can connect
So what could be happening? I have no clue. It is apparent there is some setting that gets saved within the PCs ( may be user profile) after the first log on with the Firewall off - to say its safe ?
However I have no idea what will happen if the server is restarted u2013 this server we cannot restart any time we want as itu2019s a critical server and runs other things.
I would still like to get to the bottom of this to understand what is happening.
I have a SAP message running too and will ask them this same question.

Console cannot connect to Admin Server in a local network

Hi,
This issue may has been asked before, but I didn't find corresponding answer. So I ask again:
The Directory server 5.2 P4 is running on Windows XP and a console running on the same server (192.168.1.80) works fine. However second console which is running on 192.168.1.50 can not connect to admin server. Error message is:
Cannot connect to the Admin Server "http://homeserver.keiban.com:5201/" The URL is not correct or the server is not running.
I noticed that if I use http://192.168.1.80:5201 to connect admin server instead of http://homeserver.keiban.com, it took 10 seconds to show Initialization Failure:
Connect connect to the Directory Server "ldap://homeserver.keiban.com:5200" LDAP error: failed to connect to server ldap://homeserver.keiban.com;5200 Would you like to attemt to restart the Directory Server?
In Control Panel -> Windwos Firewall -> Exceptions, I have added port number 5201 for Sun ONe Admin Server 5.2 on TCP.
In etc/host file, an entry is already added:
192.168.1.80 homeserver.keiban.com homeserver
Both computers are in a local network and via cable DSL to connect to Internet. Is there some thing I am missing?
Your help will be appreciated,

1. Make sure your FQDN is set up correct on both
client and Server.Victor, you are right! I setup FQDN on server properly, but forgot to have FQDN setup to map FQDN to IP address on client. So the Console goes to Internet to find the directory server in which it causes failure.
Thanks your hint,
a. ping xxx.xxx.xxx.xxx from client to Server
Check the Admin Server for Client Access Control
configuration.

Sample Servlet code that connects to Microsoft SQL 2008

Does anybody have sample Servlet code that connects to a Microsoft SQL 2008 Resource Pool?
Thank you.

JDBC is used to talk to databases. Not database utilities. As an example SSIS is not a database.
So the question would be is the 2008 "Resource Governor" (of which "Resource Pools" are part) a utility or a database entity?
[http://technet.microsoft.com/en-us/library/bb933866.aspx]
I would guess that it isn't a database entity.
Thus the only way to access it is if a database entity allows you do access it. And for that you would need to look for SQL Server system proc(s).

I cannot connect to Microsoft SQL Server 2008

I am getting a cannot load when I am trying to download SQL Server 2008.

Hi,
>>1)Can you look into the application log in the eventvwr for a detailed error message and post it here
Where should I look into?
Go to All programs-->Microsoft SQL Server-->configuration Tools-->Sql Server configuration manager-->SQL Server services in the left pane-->right click SQL Server -->
start..you can also see properties where in you can see Log on as tab.
In my machine i have only default instance..Based on the instances running in your machine you can see services running accordingly in here
You already told your SQL Server service is not starting..now you have tried again to start the services and the error would have been logged in the eventvwr.
Start-->cmd-->eventvwr-->Windows Logs-->application-->You can see the errors logged at the time when you tried to start SQL Server on why SQl Server was not able to start on the right side pane.
Please go through that and post those error messages in here. Since you are using it after long time there might be chances you moved your master DB's mdf and ldf files to someother location. Without master DB coming up, your instance will not come up.
Thanks

Unable to Remote connect to a SQL 2008 server

I just set up a virtual server with Godaddy with CF and SQL Server 2008
The SQL server appears to be running because if I RDC into the server and connect using the Server management Studio, it works. To find the instance I have to look at network devices and I find it under MACHINENAME\SQLINSTANCE
The problem I have is that I want to connect to this instance using server management studio on a computer with SQL2005 installed. I guess/hope that a 2005 can connect to a 2008
I'm not 100% sure what the exact correct format is for the "Server Name" when trying to set it up. I've tried everything I can think of
ServerName\IPNumber\Instance
IPNumber\ServerName\Instance
IPNumber\Instance
Nothing seems to work, it kicks back with a big error, aying it can not connect:
A network-related or instance-specific error occured while establishing a connection to SQL Server.
The server was not found or was not accessible. Verify the instance name is correct and that
SQL Server is configured to allow remote connections (provider: SQL Network Interfaces, Error: 26-
Error Locating Server/Istance Spcified) (Microsoft SQL Server)
The firewall on the server is off, I checked the properties of the instance and the option to allow remote connections is also checked
Anybody have any ideas?
Thanks
Mark

Solved this myself.
I was trying to log in with the user name of the adminstrator for the server, which worked locally while on the server but when I tried to use SQL SERVER AUTHENTICATION , tapping in the user name and password, it failed in the same way, even though the password was correct. Connecting using WINDOWS AUTHENTICATION worked, so I checked the users and found that user name did not have a password set because it was the admin I guess, so it just rejected all attempts using SQL SERVER AUTHENTICATION.
What I then did is tried the 'sa' user, and saw that it did have a password set when I viewed it in USERS... so I tried to connect remotely using that, and it worked... problem solved
Thought I'd post that, just incase anybody else came across the problem
After posting this I reversed a change that I had made from info found on another forum, and it stopped working! I put the change back again and it works, so it looks like a combo, here is the info that I found that helped fix the problem
"In the SQL server configuration manager, there is an item called SQL server network configuration, under protocols, I selected the properties of the TCP/IP protocol. There is a tab “IP Addresses” there, and at the bottom of the list is an entry called IPAll. In my case the TCP port was empty. I entered the SQL standard port 1433 in there and I was able to connect."
I had also since posting upgraded to 2008 locally, not that I believe it had anything to do with the problem

Field Explorer is empty after establishing a connection to a SQL 2008 SP

I am trying to create a report using a SQL Server 2008 stored procedure as the source of data using an ADO connection.
The stored procedure is slightly odd, in that its building up the SQL as a string, Below is a snippet of the code to show what I mean. The reason for this is that I need to build up the WHERE clause dependign on user input.
     SELECT @var_query = 'SELECT c_source,
        c_ccy,
        n_quantity,
       a_price,
       d_price,
       a_isd
                     FROM     ldsdbo.lds_testing_filter_data_vw WHERE'
     PRINT @var_query
     EXEC (@var_query)
This runs fine in SQL Server, but when I try and use it in Crystal, the Database Field list is empty.
Does anyone know whats going on, and how I can make this work?
Thanks
Nathan

Well... Now I just feel obligated to reply...
The key(s) to using an SP as your data source is to make sure that your SP does in fact return a single data set.
So... begin by testing it in SSMS. If the following works in SSMS, then it should also work in CR...
EXEC usp_MyStoredProcedure 'ParamValue1', 'PramValue2'
... note: the above example is based on the premise that the SP name is "usp_MyStoredProcedure" and you are tryig two pass 'ParamValue1' & 'PramValue2' as values...
Obviously, you should use the actual SP name and any necessary test values if it has parameters.
Assuming that the SP executes in SSMS AND returns a result set, you should be good to go in CR... Just do as Don mentioned and make sure you are using the NC10 drivers.
If you are still getting stuck, remove the SP from the Database Expert and call the SP from a Command instead. It's easy to do as it allows you to use the exact syntax you used in SSMS. You'll just want to replace any hard coded values with CR parameters... (Just add the parameters to the parameter list of the command and reference them like this...
EXEC usp_MyStoredProcedure '{?Parameter1}', '{?Parameter2}'

Cannot Connect to Azure SQL Database in Visual Studio 2013

Beyond Frustrated here.
I am trying to connect to an Azure SQL database - it has been created, has tables etc. I am trying to create a new Data Connection from within Visual Studio 2013, latest release for VS and Azure. I continue to receive 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
I have ensured that TCP is allowed and above Named Pipes in the Configuration Manager. The associated IP address is allowed on Azure Firewall. Certificate has been added to VS etc. But still no connection. I can see the database in the Azure section in Server
Explorer, but cannot add a Data Connection. What is equally as frustrating is I have a MacBook Pro running Win 7 sitting right next to my office computer and it can access Azure fine, not problems.
If anyone has any other ideas on how I might be able to solve this I would love to hear them. Thanks in advance.
Jeff

Hi,
The Error message "   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) (Microsoft SQL Server, Error: 53) "
The issue comes up mainly because the application is not able to connect to the server.
To resolve this issue, try the following steps (in that order):
Make sure that TCP IP is enabled as a client protocol on the application server. For more information on how to do this, see
Configure client protocols. On application servers where you do not have SQL Server tools installed, you can check this by running cliconfg.exe (SQL Server Client Network Utility).
2. Check the application’s connection string to make sure that it is correctly configured. For example, make sure that the connection string specifies the correct port (1433) and the fully qualified server name.
Note You can follow these steps to obtain the connection string from the Azure Management Portal:
                      Log on to the
Azure Management Portal.
                      In the left navigation pane, click
SQL Databases.
                      Select your Azure SQL Database server.
                      Click
Dashboard.
                      On the right side, go to the
quick glance section, and then click Show connection strings.
Test the connectivity between the application server and the Azure SQL database by using a UDL file, ping, and telnet. For more information about how to do this, see
Azure SQL Database connectivity troubleshooting guide and
Troubleshooting SQL Server connectivity issues.
Note As a troubleshooting step, you can also try to test the connectivity on a different client computer.
Try increasing the connection timeout. Microsoft recommends using a connection timeout of at least 30 seconds.
As a best practice ensure retry logic is in place. For more information about the retry logic, see
Azure SQL Database best practices to prevent request denials or connection termination.
      If these steps do not resolve your problem, follow the below steps to collect more data and contact support:
   If your application is a cloud service, enable the logging. This step returns a UTC time stamp of the failure. Additionally, SQL Azure returns the tracing ID.
Microsoft Customer Support Services can use this information.
   For more information about how to enable the logging, see
how to enable diagnostic logging for Azure Web sites and Developing SQL Database Applications section in
Azure SQL Database Development Considerations.
  Check out
the list of best practices for Connecting to Windows Azure SQL Database.

SQL 2000 ODBC CONNECTION STRING FOR SQL 2008

i have vb 6 application. Database is SQL server 2000.
my connection string is (using odbc driver),
        .ConnectionString = "Driver={SQL Server};SERVER=" & mServer & ";DATABASE=mydb;UID=" & mLogin.Username & ";pwd=" & mLogin.Password & ";"
Now i have tried this application with SQL server express 2008 R2
Can i still keep the old connection string? will there be any problem in future?
(if i have to change then have to change at so many places.....)
I can run application without any problem for now (not changed connection string to new one)
otherwise i have to use ODBC or OLEDB which are,
        .ConnectionString = "Driver={SQL Server Native Client 10.0};SERVER=" & mServer & ";DATABASE=mydb;UID=" & mLogin.Username & ";pwd=" & mLogin.Password & ";"
or
        .ConnectionString = "Provider=SQLNCLI10;SERVER=" & mServer & ";DATABASE=mydb;UID=" & mLogin.Username & ";pwd=" & mLogin.Password & ";"
if i have to change to new connection string Which one is better to use odbc or oledb.
h2007

personally I favor ODBC as it is easy to use sometime. Additionally you can check the link below:

Macbook clients cannot connect to Windows Server 2008 RRAS with L2TP/IPSec

Hi everyone,
I had installed "Remote and Routing Access" or a VPN server on Windows Server 2008. The connection type set up is L2TP/IPSec. All the Windows clients can connect to the L2TP/IPSec VPN server without problem but Macbook users are facing problem.
The Macbook users got the error message "The L2TP-VPN server did not respond. Try reconnecting. If the problem continues, verify your settings and contact your Administrator."
I think it is something related to the pre-shared key encryption but I am not sure. The Macbook users could connect if the connection type is changed to PPTP on server and clients side. I searched for similar problems and solutions online but no luck, I couldn't find solution that helps. I found this is a common problem faced by many macbook users.
Does anyone have a solution or suggestion for this, please? I appreciate all the helps and suggestion given.
Thanks,
CK

Hi,
Thanks for the question, however, this forum is for Remote Desktop Clients related questions.
Regarding the issue, as Windows clients can connect with no problem, I suspect that it is a Mac side issue and I would like to suggest you contact Apple support for help.
Thanks.
