How do you access a SQL Server 2005 Express Edition from a application in a network computer?
The access I need is both from application (Linq-to-SQL and ODBC) and from Management Studio
See this KB Article. How to configure SQL Server 2005 to allow remote connections.
Oh, and remember that the SQLServer name will probably be MyMachineName\SQLExpress
If you're running it on a 2k3 box, you need to install all updates for Sql Server and the 2003 server.
Check the event logs after you start the Sql Server. It logs everything well, telling you if its being blocked, and where it is listening for connections.
From a remote machine, you can use telnet to see if a sql server is listening for remote connections. You just need the IP and the port of the server (default is 1433). From the command line:
telnet 192.168.10.10 1433
If you get a blank screen, its listening. If you get thrown back to the command prompt, something is blocking you.

I have a SQL Server version 12.0 instance installed on a Windows Server 2012R2 (SERVER/SQL), and a SQL Server Express version 11.0 instance installed on a windows 10 workstation (WIN10/SQLEXPRESS). Both are on the same domain. I am logged in as the domain admin and have full rights on both SQL instances.
On my WIN10 machine I am able to create a linked server from (WIN10/SQLEXPRESS) to (SERVER/SQL).
On my SERVER when I attempt to create a linked server from (SERVER/SQL) to (WIN10/SQLEXPRESS) I am told to ensure that the instance will allow for remote connections. I have gone through about 40 hours of troubleshooting this, ensuring that all firewalls, ports, security and agents and browsers are open.
Is there any reason I cannot link a SQL Server Express to another SQL Server, but can the other way around?
I would like to be able to call stored procedures from my main SQL Server but am not able to.
Please note, the purpose for the SQLEXPRESS on the WIN10 machine is due to the vendor requirements for the software I am using. Otherwise I would have the instance on my SERVER.
Almost certianly a network issue.
Using SQL Server Configuration Manager configure SQLEXPRESS to enable TCP/IP and listen on a fixed port, preferably 1433 if no other instance is on the server. Restart the instance.
Create a Windows Firewall rule enable inbound TCP/IP connections to the port.
Test network connectivity to the target port from the other server with powershell, eg:
PS C:\> test-netconnection WIN10 -Port 1433
Test SQL connectivity with SQLCMD or SSMS on the server to the WIN10 box.
Create the linked server.
I have tried every conceivable permutation for hours to try to connect to a remote SQL Server 2017 using SSMS. I keep getting:
Logging failed for user xxx. (Microsoft SQL Server Error 18456)
I know SQL Server is running on the remote machines since I can log
in locally there using SSMS.
SQL Browser is running.
TCP/IP is enabled. There are no dynamic
ports in IP All.
I know the firewall is not a problem since I can
telnet to port 1433 from the remote machine, and I added the rule to allow access.
I have "Enable Remote Access" turned on in SQL Server.
I have both Windows and SQL Server Authentication enabled.
I have user mappings for the given databases.
I can connect locally using SSMS with the Sql Server Auth user/passwd that I am trying to use remotely.
When logging in from the remote client in SSMS:
I use an IP address for the server (although I can also browse to the server as I have UDP 1434 open).
I use SQL Server Authentication.
I looked at Event Viewer on the SQL Server machinee to see if it gives me more clues as to why the log in is failing, but it is worthless.
I saw this, but it is of no help.
What on earth could be left that is the problem?
Software:
Windows 2012 server R2
SQL Server express (64 bit), installed by choosing all defaults
SQL Server 2014 Management Studio, installed on the same machine
When I connect from SQL Server Management Studio to SQL Server, it works fine as long as I have "Network protocol" on the connection tab set to <default>.
When I set the protocol to TCP/IP, the connection fails:
A network related error ... The server was not found or was not accessible...
I checked with the SQL Server Configuration Manager that TCP/IP is enabled on the server as well as on the client. I can't find help from Google.
One observation: after the installation, the SQL Server Configuration Manager would not come up (Configuration Manager Cannot Connect To WMI Provider). I followed this advise (https://www.youtube.com/watch?v=igl-CB0qP_c) and got it to work.
I am unable to post a comment due to reputation score so I had to post an answer.
Some things to try/check:
Start the SQL Browser Service if it is not running
Check the SQL Error Log to ensure it is running on port 1433
Are you connecting to servername\SQLEXPRESS in the connection dialog
Try telnet to connect telnet servername port
if it goes to a blank screen instead of giving you a failure to connect then it is communicating. Ctrl + ] to cancel the connection.
Hi
I have sql server 2008 and an express version which was installed as part of Visual Studio.
I want to see the 2008 version in the network servers of SQL Server Management Studio.
If the SQL browser service is disabled I can see my 2008 instance listed. If it's enabled
I only see the sql express version?
Either way I can't see the 2008 version from other machines
Any ideas?
Thanks
p.s.
Firewall is off locally
I don't know why one shows up locally when the browser server is disabled and the other when it is enabled, but as far as seeing them on other machines make sure UDP port 1434 is open on any firewall software you are running locally as the SQL Browser service uses that port.
http://msdn.microsoft.com/en-us/library/ms181087.aspx
"Upon startup, SQL Server Browser
starts and claims UDP port 1434. SQL
Server Browser reads the registry,
identifies all instances of SQL Server
on the computer, and notes the ports
and named pipes that they use. When a
server has two or more network cards,
SQL Server Browser returns the first
enabled port it encounters for SQL
Server. SQL Server Browser support
ipv6 and ipv4."
Unless it has changed recently, by default, SQL Express does not listen for remote requests (on the network), just locally. But, that can be changed if needed.
Hi i want to know how to enable remote server connection in sql server 2000. I have sql server 2000 installed in a system with windows server 2003 os. i want to create a dsn connection to the database through remote. I have created a dsn locally in the server it is working. but how to create dsn from the remote system and make it work.
To allow remote connections to the server, do the following:
In SQL Server Enterprise Manager, right-click the server and choose Properties.
On the General tab, click the Network Configuration button and enable Named Pipes, and TCP/IP in the new window. I'm not sure if you need to restart SQL Server after doing this.
After doing this, you should be able to connect to the SQL Server from a remote computer, by referring to e.g. MYSERVER\MyInstanceName.
It helped me.
BTW I've also added sqlservr.exe to my firewall exception list:

Try installing MSDE/connectivity tools on remote system.
