thanks
Check out surface area configuration. It gives options to do so.
Edit: Enable the Named pipes conenction as well. I guess you are using Named pipe to connect. Also check if the SQL server browser service is running on the DB server.
Check the Authentication mode settings. It may be set to Windows Authentication only, it needs to be in Mixed Mode to accept SQL usernames & passwords.
Also check the Server network configuration and make sure named pipes or tcp/ip are enabled add that the client is using the appropriate protocol.
If everythings are correct, you may want to connect with a upper version, for example you are in SQL Server 2005 and want to connect to SQL Server 2008.
Note that you cannot connect to a upper version.(only same version or older version are granted)

Trying to connect to SQL Server from Excel by using >>Data tab, >>From other sources >> from SQL server. It came back with the attached message
I made sure named pipes and TCP/IP are enabled in the SQL server configuration manager. It works on my laptop. But my friend is trying to install in her laptop and it is not working. Appreciate any ideas you can share with us. We are doing Developer Edition, custom install of the database server. Double checked the instance name and made sure remote connection is allowed.
This is the error message I get
Unable to connect:
We encountered an error when trying to connect.

I'm trying to connect from a local SQL Server Management Studio to a SQL Server hosted in a VM on Azure.
I followed all the instructions from
http://www.windowsazure.com/en-us/manage/windows/common-tasks/install-sql-server/ and created the necessary endpoints:
Somehow, I can't connect to the SQL Server, getting this error
Cannot connect to xxx.cloudapp.net.

I already tried to temporary disable the windows firewall on the vm - without success. Any suggestions?
I had the same problem, this troubleshot helped me getting close to the solution:
Use SQL Server Management Studio to connect remotely to an SQL Server Express instance hosted on an Azure Virtual Machine
Summing up, what i did, i don't know if all these steps are necessary, so you should test after each one:
1) In SQL Server configuration manager enable Named Pipes in protocols
2) In the VM add a windows firewall inbound rule for sql server port (in my case the default 1433, in yours it seems to be 1435, make sure it's 1435 in sql server configuration)
3) Make Sure you are using a sql server authentication login (not a windows authentication) if you don't have one create it locally in the VM>MSSMS
4) Make Sure the SQL server is configured for mixed authentication (http://www.katieandemil.com/microsoft-sql-server-error-18456-login-failed-for-user)
5) Make sure sql server browser is running
Hope this helps :)
I am trying to connect to MS SQL Server 2008 R2 Express Edition through a Remote computer.
I am getting this 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)
On running SELECT CONVERT(char(20), SERVERPROPERTY('InstanceName')) instancenameting
I get NULL as the instance name. I have started SQL Browser service, checked TCP/IP are enabled.
What else can be done?
Use
Data Source=IP-0A6E3175;Network=DBMSSOCN;...
Or
Data Source=<<ip address>>;Network=DBMSSOCN;...
You'll also need to make sure that TCP/IP is enabled on the host using SQL Server Configuration Manager, that you aren't blocked by a firewall, etc.
And just for kicks, also please try:
Data Source=<<ip address>>\SQLEXPRESS;Network=DBMSSOCN;...
In addition to Aaron's suggestion to ensure your connection string uses tcp, run SQL Server Configuration manager and check the following:
do you have more than one instance?
tcp/ip enabled?
if the instance you are targeting is not the default instance, it will not be on port 1433 but rather some dynamic port. The Microsoft libraries figure out which port using SQL Server Browser on port 1434. Your firewall needs to allow that also (UDP).
if your Express instance is the only instance, you can change to use port 1433. Then you don't need SQL Server Browser.
In Visual Studio 2010 I am trying to set up a connection with a SQL Server database with the add connection wizard but the connection fails!
This is the error I get:
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 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)
Extra info;
I can ping the server!
Remote connections are allowed on the SQL Server!
SQL service is running!
What is here the problem?
To work around this problem, use one of the following methods depending on the symptom that you are experiencing:
A SQL Server login
Use a valid Windows login to connect to SQL Server. If you must continue to use a SQL Server login, you can change the security authentication mode in SQL Server to SQL Server and Windows.
A Windows account with insufficient permissions
To work around this problem, you must add the Windows account to SQL Server, and then grant the appropriate permissions to each database that the user requires access to.

I am remotely accessing SQL Server Express 2008.
I have turned on service "SQL Server Browser"
I have turned on service "SQL Server (SQLExpress)"
I have enabled TCP/IP and set dynamic ports to blank and tcp port to 1433 in properties
I can connect localy(using ip) so my credentials are correct.
I have a exceptions record in my windows firewall setting port 1433 as open.
I have performed a system reboot making all services are still turned on.
After i try and connect via a remote computer I get this error.
Cannot connect to XXX.XXX.XXX.XX

Hi and thanks for the quick responses. At present there is no connection string. I am trying to connect using: SQL Server Management Studio 2008

Hey Nick.
I am connecting using SERVERNAME\SQLEXPRESS I turned off windows firewall off and still there was no joy.
I tried adding the port like you suggested:
===================================
Cannot connect to XXX.XXX.XXX.XX, 1433.
===================================
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: TCP `Provider, error: 0 - No connection could be made because the target machine actively refused it.) (.Net SqlClient Data Provider)`
please show us the connection string in you are using to connect to the server with.
If your connecting using the instance name. eg. SERVERNAME\SQLEXPRESS then you will need to open up your firewall for the SQL Browser service i.e. UDP port 1434.
Alternatively, try using the port in your connection string and forget the instance name. Eg. in SSMS you can connect using SERVERNAME,1433 where 1433 is the port you've specified sql server listens to.
You say you have configured TCP/IP but your connection error message says this:
provider: Named Pipes Provider
Update
It appears you have one protocol enabled on Sql Express and are trying to connect with another via Sql management Studio. You need to connect with the TCP provider or enable Named Pipes on your Sql Server Express Configuration.
To connect with TCP, in Sql Management Studio click the Options button on the login page. This will take you to a Connection Properties page where you can select the provider. The Network protocol is probably set to default or Named Pipes at the moment and it needs to be changed to TCP.
Alternatively, in Sql Server Configuration Manager, enable Named Pipes in Protocols for Sql Express.
