I've set a up a small SQL Server database on my laptop, I would like to access it from my Desktop PC, I'm a bit confused.
I've already Enabled TCP/IP protocols from SQL Server Configuration Mnagement, and I've already opened a port on the Windows Firewall and enabled remote connection on the database i want to connect to and added a login account to use for the connection.
From my desktop's SQLServer Managent instance,I've tried putting as ServerName, both the name I see on my laptop, (which I guess it's the local name of the machine) and the public IP adress + port, but nothing happens.
How do I get the two computers to communicate?

I have SQL Server Express installed on an Azure Windows Virtual Machine.
Steps I have taken:
updated the default port for SQL server in SQL Server Configuration Manager.
verified sql server is listening on that port (netstat -ano)
Added a Windows firewall rule to accept inbound traffic on that port (Scope of the rule limits to my static IP address)
added an inbound rule in Azure to allow access to that default port (Source IP address same as IP in Windows Firewall)
Verified Remote Connections are enabled in SSMS
Mixed authentication is enabled.
Verified user created is able to access the desired databases by logging in locally with Sql Server Management Studio. This is a sql server user and not a computer account
I am able to telnet and nc to the port.
The name of the SQL Server looks like this when i access it locally on the VM
localhost\SERVER_NAME or
hostname\SERVER_NAME
From a remote machine I am attempting to access this database using SSMS.
I have tried:
mydomain.com\SERVER_NAME -mydomain.com does resolve to the correct IP address
mydomain:1234\SERVER_NAME -1234 represents the default port that was set
I have verified the user name and password are correct. I have also tried turning off the Windows firewall which leads me to believe it might be the inbound rule in Azure but there's really nothing special to that rule, just allows traffic to the sql server port (1234, in this example).
What am i missing?
Can you please have a look to this article, if you did not yet, and ensure that you did all the steps required? To highlight a few important steps, please ensure:
Set the connectivity to publish
Use SQL Server Configuration Manager to manually enable the TCP/IP protocol
Use the SSMS to connect to your DB and use the following server address for your VM
Hope that it helps.
The correct connection string in SSMS is
mydomain,1234\SERVER_NAME
comma before port not colon.
i moved my website on a server, it have installed web application and SQL server instance (this site is only for private network), if i try to access sql instance from SSMS it connect without problem, but when i try to access data from my website or SSMS installed on another pc connected to the same network it's says me that instance name is not correct or firewall block sql server ports. Sql connection string is correct, both SQL Server and SQL Browser services are active, named pipes and TCP are enabled, and i've added rules to firewall to allow connection from port 1433 and 1434(this one is for UDP) but i've the same problem, any help?
I have created an Application in VB.NET with database in MSSQL 2014.
I have configured TCP/IP=1433, UDP=1434, Windows Firewall is configured to allow 1433, 1434, sqlserver.exe, sqlbrowser.exe and server's login settings are configured. Application is working on my laptop which is on the same Internet connection as the host computer. I am trying to use the Application on client computer which is on another network and getting NAMED PIPES PROVIDER error40.
This is connection I am using:
Data Source=myServerName;InitialCatalog=dbName;UserId=clientcomputerName;Password=x
Do I need to configure client's computer in any way?
Does your DNS/HOSTS file resolve the remote computer name? Try IP address instead if not. Not sure but not all versions of SQL support remote connections via Named Pipes (can sometimes get round this by using registry hacks to add the connection as ODBC)
I have opened up port 1433 on my firewall, but every time I try and connect to my remote SQL Database with SQL Server Management Console I receive (Microsoft SQL Server, Error: 53)

Enable remote connections for SQL Server Express 2012
Short Answer
Check Firewall
Check Service is Running
Check TCP/IP is Enabled
Check SQL Server Properties "Allow Remote Connections"
Check if the SQL Server is on a restricted subnet
Then Run these if Those Do not Resolve
Right-click on TCP/IP and select Properties.
Verify that, under IP2, the IP Address is set to the computer's IP address on the local subnet.
Scroll down to IPAll.
Make sure that TCP Dynamic Ports is blank.
Make sure that TCP Port is set to 1433.
If you have a named instance then you must have the SQL Server Browser Service enabled
The browser service runs on port UDP 1434 and this must be allowed through your firewall
Hail Mary Pass if this is Still not Resolved
Go to the client machine, and run cliconfg.exe If named pipes is listed first, demote it, and promote TCP/IP.
check if the firewall is blocking the named pipes port, which usually is 445
What you need to do is go into SQL Server Configuration Manager where SQL Server is installed.
In the Start Menu, under the Microsoft SQL Server folder, open the Configuration Tools folder and select SQL Server Configuration Manager.
In the Config Manager, click the arrow next to SQL Server Network Configuration, then click on "Protocols for {Instance}". {Instance} will be your install, if it's the default instance it will be MSSQLSERVER.
On the right side, make sure that TCP/IP is "Enabled". Double click TCP/IP, in the window that opens, change the drop down to "Yes".
Here is the how to fix it and gain your connectivity back:
Click WindowsKey + R and enter services.msc
Once Services opens scroll down and locate service SQL Server
Highlight the service and click START
Wait for the service to start and retry to connect to your MSSQL instance
It should now work again and you will be able to connect to your MSSQL instance and run queries.
I have solved this problem. Please refer to this thread: http://social.technet.microsoft.com/Forums/forefront/en-US/d2624655-e6ff-4947-b1a8-a2edcffd8a21/denied-connection-netbios-session-protocol#68321990-4ac4-46fa-b7f8-9e0ded3234bb
In detail: I was receiving the following error from ISA when trying to connect from my SBS 2003 Server to my offsite MSSQL Database Provider via SQL Server Management Studio:
Denied Connection
Log type: Firewall service
Status: A packet generated on the local host was rejected because its source IP address is assigned to one network adapter and its destination IP address is reachable through another network adapter.
Rule:
Source: Local Host ( 192.168.1.1:29859)
Destination: External (...:139)
Protocol: NetBios Session
I have figured this out. I had to add "Local Host" as one of the sources for the ISA Rule that I had initially created to allow SQL Server Management Console connections in the first place. That rule was allowing "Internal" sources but not the Local Host (127.0.01), which is needed for this scenario.
in SSMS while opening give the server name as your_Hostname\your_sqlservername (give both the names as applicable instead of local or just only servername) it works fine.
I could ping my Virtual Machine SQL server but couldn't connect to it.
I disabled my wired and wireless NICs and then it connected !
I'm running SQL Server 2008 Express on Windows XP on a VirtualPC instance inside a Windows XP host. I want to be able to connect to databases on the guest instance using SSMS on the host. When I go to connect from SSMS on the host, and browse for servers, I see the instance of SQL Server on the guest. Yet when I try to connect, using a SQL authentication login, I get the following connection 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: 28 - Server doesn't support requested protocol) (Microsoft SQL Server, Error: -1)
I have:
* tried connecting with both Name Pipes and TCP/IP
* ensured that the SQL Browser service is up
* ensured that the firewall on the guest is open
* the server is configured to allow remote connections (according to the database engine properties within SSMS on the guest)
What am I missing?
EDIT: I figured this out. My resolution is below.
SELF-ACCEPTED ANSWER
Thanks for the ideas. After much fiddling I got things working. It turned out that I had not gone into the Sql Server Configuration Manager and enabled TCP/IP and Named Pipes as network protocols. So even though SSMS said remote connections were enabled, there was no protocol to allow for them other than shared memory. After I did this I restarted the SQL Server service, but things still didn't seem to work properly. Yet once I had rebooted both the guest and host, everything was working as expected.
How are your IP settings? Are you sharing the same IP address between the two machines? If so, then perhaps when your clients attempt to connect to 10.1.1.10, it is hitting the IP of the machine hosting the VPC instance, and that machine is not running the SQL Server instance. If possible, have VPC get its own IP and try that.
Mostly double check what you have already said,
turn off the guest firewall to make sure it isn't that.
Make sure your virtual machine networking is set to bridged and not NAT.
Try connecting to the IP address of the guest instead of its name.
Make sure the remote connections are allowed by SQL server and that both client and server are using tcp/ip (or named pipes if you prefer).
I don't know if enabling remote connections requires a restart of SQL server.
Try using SQL authentication to eliminate an authentication issue. Are you running on a domain?
To add some steps that are not explicitly called out above, what worked in my experience was to set up the Virtual PC's Networking to my physical network adapter.
Then disabled Windows Firewall for the Public Profile.
Hopefully could actually lock that down to port 1433.
Also, on the guest OS, if SQL Server is installed with only Windows Auth, you later add SQL auth, note that by default 'sa' is disabled for login access. Either 'enable' Login for 'sa' or (better idea) create Logins with appropriate permissions as needed.
