I have problem with connecting to Sql Server from my local machine.
Seems like I did everything I could, but still I'm unable to connect to it.
This is what I did:
1) Right click on Sql Server in Sql Management Studio (SMS) -> Connections -> Allow remote connections
2) Right click on Sql Server in Sql Management Studio (SMS) -> Security -> Allow remote connections -> Set Auth mode to Win and Sql auth mode (i.e. mixed mode)
3) Disabled firewall
4) Sql Server Configuration Manager -> Network Configuration -> Protocols -> Enable Shared memory, Named pipes, TCP/IP
5) Sql Server Configuration Manager -> Network Configuration -> Protocols -> TCP/IP -> Properties -> Set TCP Port to 1433, Set TCP Dynamic Port to 0. After that I restarted MainSql service in "services.msc"
6) I ran "EXEC xp_readerrorlog 1" in SMS, found this:
Server is listening on [ 'any' 1433].
Server is listening on [ 'any' 1433].
Server local connection provider is ready to accept connection on [ \.\pipe\SQLLocal\MAINSQL ].
Server named pipe provider is ready to accept connection on [ \.\pipe\MSSQL$MAINSQL\sql\query ].
Server is listening on [ ::1 64825].
Server is listening on [ 127.0.0.1 64825].
7) Tried to telnet [myip] 1433 from my home machine. Result: connecting To [myip]...Could not open connection to the host, on port 1433
: Connect failed
8) Tried to telnet [myip] 1433 from server - it worked!
Seems like this is some kind of a network issue. I have another server with Sql Server installed, I did the same on it and I was able to connect to it from my home machine, but not this one! I tried to connect to this server from the second one and it didn't work too.
Please help me, I don't know what to do. I did everything I could but it still doesn't work.
Update:
Sql Server Browser service is started on the server machine. The server is a dedicated server at a hosting, I'm trying to connect to it from my home machine and from another server witch is a dedicated server as well, from another country.
The problem was in firewall. To fix it I ran a script from here: http://support.microsoft.com/kb/968872
This is really strange because I fully disabled server's firewall. However it now works for me, thanks to cairnz and Gregory A Beamer for help.
It looks like you hit one of two most likely causes: You have set protocols. Just double check the client side to ensure the same protocols are enabled on both sides and you are done there.
The second most likely, with SQL 2005 on, is the Browser service is turned off on the server. If this is true, you will often have issues with remote calls, ala http://support.microsoft.com/kb/914277.

I have an interesting issue connecting to a MySQL database remotely on my Windows 7 machine at work.
I'd like to connect to a remote MySQL database stored by hostpapa. At home on my mac, I use the following code successfully (after ensuring that my home mac IP address is an allowed user on the database side):
library(RMySQL)
# Connection Database SQL with RStudio
db <- dbConnect(MySQL(),
user='admin',
password='mypassword',
dbname='admin_dbase',
host='mywebsite.ca')
It connects to the database and I'm able to view tables, etc.
In Windows - same code - no luck. Error message is:
Error in .local(drv, ...) :
Failed to connect to database: Error: Can't connect to MySQL server on 'mywebsite.ca' (0)
I've attempted to add RStudio and R to the Windows Firewall as "allowed programs" and I've also gone to Windows Firewall -> advanced settings -> Inbound rules -> New Rule -> and added a TCP Port for port 3306. (I also tried adding port = 3306, as an argument in the dbConnect call).
Now, I know these credentials work on my mac, so it's gotta be something to do with the settings on my Windows machine. Also, the error message doesn't say there isn't a MySQL database, it just complains it can't connect.
Any ideas on how to convince my work machine to play nice?
Note - *I'm new to connecting to databases, so a descriptive answer would be much appreciated!**
I am working on windows and having a remote desktop connection of another machine. I am trying to connect to the mysql running on the remote machine through my MySql workbench, installed on my machine.
When I specify the details to connect to mysql i.e.
IP- a.b.c.d
port-3306
username=root
password=
But everytime it shows me an error saying-
Your connection attempt to connect to user='root'failed from your host to server at a.b.c.d:3306
Is it possible that I can connect to mysql on a different machine?
Certainly that is possible, mysql is a network transparent service. However obviously the normal access authorization rules apply.
do you have network access to the mysql port, this might be blocked by a firewall. You can check that by using telnet ip-address-of-server 3306. Does the server answer or do you get a timeout or are blocked? (the answer would look cryptic, soomething like 5.5.33-MariaDB[*[n7p~g!�iXccI$r9``Y{$mysql_native_password or similar )
the mysql server can be configured to not listen to remote connections. This can add security to the setup, but would obviously block any remote connection attempts. You will have to check the configuration files of mysql for that.
mysql itself implements an authorization level. So check if that 'root' user actually is allowed to connect from the outside. Those authorizations are stored in the internal "mysql" database.
Also it is not clear from the question what your network topology is: is the mysql server running on that system you have a "remote connection" to? Is the mysql-workbench running on that remote system or on your local system? This might affect the ip address you have to use inside the workbench.
I have a sql server hosted on go daddy that I simply am unable to connect to using Visual Web Developer 2010 Express or Microsoft SQL Server Management Studio.
Cannot connect to RBSAssetTracker.db.2574383.hostedresource.com.
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: 67)
Am I missing something? This seems like it should be relatively simple to accomplish this.
first check whether you can ping the database server then check following
Step 1) Make sure SQL SERVER is up and the instance you try to connect is running.
Step 2) Your system Firewall should not block SQL Server port.
Step 3) Go to Computer Management >> Service and Application >> SQL Server 2005 Configuration >> Network Configuration
Enable TCP/IP protocol. Make sure that SQL SERVER port is by Default 1433.
Step 4) Now follow this KB Article of MSDN depending on your server : http://support.microsoft.com/default.aspx?scid=kb;EN-US;914277
open your godaddy account,
click launch under your webhosting menu,
click on SQL server database
click actions-->details and watch for the 'hostname'
it will be like : databasename.db.99999999.hostedresource.com
copy and paste that thing to 'Server name' while logging to your management studio
Enter your godaddy sql-server database username and password to login in management studio. It should work right.
I am trying to connect remotely to SQL Server 2008 R2 Express on a server running Windows Server 2008 R2. I 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: TCP
Provider, error: 0 - A connection attempt failed because the connected
party did not properly respond after a period of time, or established
connection failed because connected host has failed to respond.)
I think the problem might be related to my connection string, because I am not sure exactly what it should be. I understand the connection string should take the form:
Data Source=123.123.123.123\InstanceName;Initial Catalog=MyDBName;user id=MyUserName;password=MyPassword;
The instance name of my SQL Server installation takes the form ComputerName\SQLEXPRESS. This is what I see when I log in to Management Studio on the server. So should the connection string begin with
Data Source=123.123.123.123\ComputerName\SQLEXPRESS
This looks wrong because of all the slashes. I have tried to omit the computer name thus:
Data Source=123.123.123.123\SQLEXPRESS
I also read somewhere that you can specify a port so I have also tried
Data Source=123.123.123.123,1433\SQLEXPRESS
because I understand that 1433 is the TCP port used by SQL Server and
Data Source=123.123.123.123,1434\SQLEXPRESS
because I understand that 1434 is the UDP port used by SQL Server browser.
I have also tried every combination of these and they all give the same error.
These are the steps I have taken to enable remote browsing on the server:
In Management Studio, right click the instance, go to Properties, Security and check SQL Server and Windows Authentication Mode. On the connections tab I have checked "Allow remote connections to this computer".
In SQL Server Configuration Manager I have enabled all four connection options (Shared Memory, Named Pipes, TCPIP and Via) under every node they occur. Under protocols for SQL Express I have tried specifying port 1433 and also leaving it blank with TCP Dynamic Ports set to 0 (which I think is meant to enable dynamic ports).
I have created firewall exceptions for TCP Port 1433, UDP Port 1434, and program exceptions for sqlservr.exe and sqlbrowser.exe.
If someone could tell me which of the four versions of the DataSource part of the connection string I should be using it would be a great help, even if it did not solve the problem. It would mean that everything I try subsequently I would only have to test once instead of four times.
Thanks in advance for any help!
Where did you enter the firewall exceptions, on your machine, on the server, or both?
The second connection string is the only really valid one. Can you telnet to the server on port 1433? Can you connect to the instance from Management Studio remotely and the problem is only from your code where the connection string is? Did you try running the same code on the server? Did you try forcing TCP/IP (vs. named pipes/shared memory etc) adding the following parameter to your connection string:
Network=DBMSSOCN;
This question comes up quite a lot and I'm sure you're hitting something that others have hit before. Have you gone through this article, "How to troubleshoot connecting to the SQL Server Database Engine"? Also there are 20+ questions on here that mention this error message and Express, according to this search result. I suggest double-checking your settings against some of the items in those answers that solved the issue for other users.
I have a remote SQL Server Express (2008 R2) with an IP: xx.xxx.xxx.xx and an instance name: myInstance.
I have been trying to connect to a DB (myDB) as user (dbUser) and with password (myPass).
I have tried various string combinations but none works. I am sure I got it wrong because the server is ok, I can ping the IP Address, SQL Server runs on port 1433, which is open. I have also enabled browser service and remote connection on the server.
Please someone give me the correct string...
How to: Configure Express to accept remote connections
There could be many reasons for this, however, you didn't post any useful details such as error messages or what exception was thrown (if any).
Check that Windows Firewall allows access on port 1433 - this is the most likely reason for the failure, since you are using an IP address and not the name of the instance.
I suggest looking at http://connectionstrings.com to check your connection string.
