I'm not able to connect to sql server with anything but 127.0.0.1 on the server machine. If I try to connect via actual IP on the network it does not work locally or remotely.
The environment is SQL Server 2005 on Windows Server 2000. My goal is to connect to this SQL Server instance from a remote machine.
I've tried telneting to port 1433 using the actual IP and that fails. I've tried turning off Windows Firewall completely
Any ideas or help is greatly appreciated! Thanks
You have to enable remote connections - check this KB article
Did you check the firewall settings. You need to create exceptions to allow remote connections in the firewall

I try to connect to my local installed microsoft sql server 2005.
In the firewall I allowed port 1433 for inbounding traffic. There is only the windows firewall active.
In my SQL Server, I allowed remote connections for the instance of my Server and for the SQL Browser.
When I open the console as admin and Type:
Sqlcmd
I get a message, that says: "Error establishing a connection.....allow remote connections".
What could be the issue?
Open the SQL Server Configuration Manager and select your server's Network Configuration node.
Be sure that TCP/IP is enabled inside the protocols subnode.
Are you sure the firewall is open and that sql server is running on port 1433?
Have you tried to telnet to the sql server port from your local workstation using windows command line i.e.
telnet servername|ipaddress 1433
(telnet might not be installed on your windows as default, easy to enable via windows add/remove programs.
If the telnet is successful you will get a black box with a blinking cursor, this proves that the local can connect to the server)
I am not able to connect to a SQL Server 2005 hosted on a Win7 virtual machine. I am new to VM, can someone help me locate the problem?
I am able to connect another SQL server which is installed on the local machine.
When you say you can't connect - that can mean a lot of things - really you need to be much more specific.
In addition to the comments and answers already here - If you're having trouble connecting to it in Sql Server Management Studio - you should open Configuration Manager on the VM itself and make sure that Shared Memory and Named Pipes are enabled (open the SQL Server Network Configuration node in the tree).
For example, SQL Server Express instances are configured by default to reject the kind of remote connection that SSMS wants to open by default.
first of all check your connection string (for reference):
http://www.connectionstrings.com/
Second you need to add an exception in the guest machine firewall or completely disable it (port 1433 is for sql tcp/ip access).
this works fine for me:
SQLConn.ConnectionString = "Network Library=DBMSSOCN; Data Source=xxx.xxx.xxx.xxx,1433;
Initial Catalog=mySQLServerDBName; User ID=myUsername;Password=myPassword"
good luck
I am trying to connect to the SQL Server 2008 Express from my local machine but for some reasons I am not able to connect to the server.
sqlserver.exe is allowed in the firewall
TCP protocol is enabled
sqlexpress is running
allowing remote connections to the server
When I disabled the firewall for the public connections it is working fine
Any other suggestions please
from what I read I think the problem is the firewall
I came a cross an answer I didn't try it, it could be helpful
the solution was found here
I want to connect from home using SQL Server 2005 to another PC.
I had a look on the msd...but before connecting it says I should connect to another computer
using the computer management and it didn't work out....I can only connect to computers from my workgroup?
Thanks,

This is just some additional information that might help anyone. I want to make it abundantly clear that what I am describing here is possibly:
A. not 100% correct and
B. not safe in terms of network security.
I am not a DBA, but every time I find myself setting up a SQL Server (Express or Full) for testing or what not I run into the connectivity issue. The solution I am describing is more for the person who is just trying to get their job done - consult someone who is knowledgeable in this field when setting up a production server.
For SQL Server 2008 R2 this is what I end up doing:
Make sure everything is squared away like in this
tutorial which is the same tutorial posted above as a solution by "Dani" as the selected answer to this question.
Check and/or set, your firewall settings for the computer that is hosting the SQL Server. If you are using a Windows Server 2008 R2 then use the Server Manager, go to Configuration and then look at "Windows Firewall with Advanced Security". If you are using Windows 7 then go to Control Panel and search for "Firewall" click on "Allow a program through Windows Firewall".
Create an inbound rule for port TCP 1433 - allow the connection
Create an outbound rule for port TCP 1433 - allow the connection
When you are finished with the firewall settings you are going to want to check one more thing. Open up the "SQL Server Configuration Manager" locate: SQL Server Network Configuration - Protocols for SQLEXPRESS (or equivalent) - TCP/IP
Double click on TCP/IP
Click on the IP Addresses tab
Under IP1 set the TCP Port to 1433 if it hasn't been already
Under IP All set the TCP Port to 1433 if it hasn't been already
Restart SQL Server and SQL Browser (do both just to be on the safe side)
Usually after I do what I mentioned above I don't have a problem anymore. Here is a screenshot of what to look for - for that last step:
Again, if someone with more information about this topic sees a red flag please correct me.
If you want to connect to SQL server remotly you need to use a software - like Sql Server Management studio.
The computers doesn't need to be on the same network - but they must be able to connect each other using a communication protocol like tcp/ip, and the server must be set up to support incoming connection of the type you choose.
if you want to connect to another computer (to browse files ?) you use other tools, and not sql server (you can map a drive and access it through there ect...)
To Enable SQL connection using tcp/ip read this article:
For Sql Express: express
For Sql 2008: 2008
Make sure you enable access through the machine firewall as well.
You might need to install either SSMS or Toad on the machine your using to connect to the server. both you can download from their's company web site.
all of above answers would help you but you have to add three ports in the firewall of PC on which SQL Server is installed.
Add new TCP Local port in Windows firewall at port no. 1434
Add new program for SQL Server and select sql server.exe
Path: C:\ProgramFiles\Microsoft SQL
Server\MSSQL10.MSSQLSERVER\MSSQL\Binn\sqlservr.exe
Add new program for SQL Browser and select sqlbrowser.exe
Path: C:\ProgramFiles\Microsoft SQL Server\90\Shared\sqlbrowser.exe
I'll edit my previous answer based on further info supplied. You can clearely ping the remote computer as you can use terminal services.
I've a feeling that port 1433 is being blocked by a firewall, hence your trouble. See TCP Ports Needed for Communication to SQL Server Through a Firewall by Microsoft.
Try using this application to ping your servers ip address and port 1433.
tcping your.server.ip.address 1433
And see if you get a "Port is open" response from tcping.
Ok, next to try is to check SQL Server. RDP onto the SQL Server computer. Start SSMS. Connect to the database. In object explorer (usually docked on the left) right click on the server and click properties.

Goto the Connections settings and make sure "Allow remote connections to this server" is ticket.

Here is the link ... You must read it.
i m creating an application, inwhich client has to acces a database stored in a remote location connnected through a live ip. how can i connect simply with a database server placed in LAN. both using sql server 2005 express edition. please refer me or help me on this
Set in your connection string IP address of remote server.
E.g.
"Data source=192.168.0.13; Database=MyDb;User ID=my_user;password=12345"
where 192.168.0.13 is your remote server IP and MyDb is your database name.
Also, make sure to configure your SQL Server Express to allow remote connections! Those are disabled by default after installation.
Check out the SQL Server Surface Configuration tool (if I'm not mistaken) to configure these settings.

This not about programming. You have forward the port which Sql Server uses on modem.
