How To Get A Remote Connection To SQL Server Express From VB 2005 Express In A Network PC That Is Granted For Administrator Use
Aug 22, 2007
Hi all,
I have SQL Server Express and VB 2005 Express installed in a Microsoft Windows XP Pro PC that is a terminal PC in our office Network. My Network Administrator has granted my terminal PC for Administrator Use. I tried to do the ADO.NET 2.0-VB 2005 programming in my terminal PC and I could not get a remote connection in the Window Form Application via Window Authorization. I do not know how to make this kind of remote connection in my Network. Please help and advise.
Thanks in advance,

Hi all,
In my office computer network system (LAN), my Windows XP Pro PC has SQL Server Express and VB 2005 Express installed and I was granted to have the Administrator priviledge to access SQL Server Express. I tried to create a SQLCLR project in my terminal PC.
1) I tried to set up a remote connection to SQL Server Express in the following way: SQL Server EXpress => SQL Server Surface Area Configuration. In the Surface Area Configuration for Service and Connection - local, I clicked on Remote Connection of Database Engine, SQLEXPRESS and I had a "dot" on "Local and remote connections" and "Using TCP/IP only". Then I clicked on "Apply" and "OK" buttons. Then I went to restart my database engine in SQL Server Management. When I went to check SQL Server 2005 Surface Area Configuration, I saw the arrow is pointing to "Service", not to "Remote Connections"!!!??? Is it right/normal? Please comment on this matter and tell me how I can have "Remote Connecton" on after I selected it.
2) After I restarted the database engine (I guess!!), I executed the following project code (copied from a book) in my VB 2005 Express:
//////////////--Form9.vb---/////////////////

Troubleshooting tips:
Store application data in isolated storage.
When deploying an Office solution, check to make sure you have fulfilled all necessary requirments.
Use a certificate to obtain the required permission(s).
If an assembly implementing the custom security references other assemblies, add the referenced assemblies to the full trust assembly list.
Get general help for the exception.

Many Thanks in advance,

Hi All,
I've developed an application that connects to a SQL Server 2005 Express database. I created a DSN to connect to the database through ODBC. Currently, I am testing locally and everything works fine.
I would now like to install my application on another workstation and connect remotely to the database located on my development machine.
The client workstation does not have SQL Server 2005 Express installed on it because I would just like my application to connect remotely by creating the DSN and using ODBC. What I'm missing here are the database drivers. The "SQL Natice Client" is not available on this client workstation. How can I deploy the necessary drivers with my installation file so that I may create the required DSN name using the SQL Native Client driver?
Thanks!

Hi
I have VC++ express and MSSQL SMS express and have an application working nicely locally. The Data explorer and data connections part works really easily.
Now, I want to make the application available to my home network.
I mapped the drive where the database is and called it Z: so I could put my "release" on my other network PC and assumed it would find Z: if I mapped the shared network drive on that machine and called it Z:
But: I can't even add the mapped connection on the local machine, I get:
The file "Z:databasescalorie.mdf" is on a network path not supported for database files. An attempt to attach.....etc"
It works fine on the original F drive.......
Am I approaching this the wrong way. How should I distribute to network PCs?
thanks hopefully
David

Hi all,Just wondering if SQL 2005 express edition can be connected remotely. I've set up SQL 2005 Express on a separate machine and am having trouble connecting to it from VWD when creating the websites. Currently I've set up ASP.NET 2.0 Framework on the remote machine with IIS6 using Windows Server 2003 Web Edition. And I am directly editing the website remotely on the server machine from my PC. Could someone please help me in setting up a remote connection from VWD to the SQL Server?I've enabled TCP/IP setting in the SQL Configuration Manager but still getting errors. Could this be an issue with Express Edition? Because if it is I also have a copy of SQL Server 2005 to install. Any direction to resolve in this issue would be greatly appreciated.PS. I'm new to this so pls bear with me. Thanks.

Hi,
I have written a database application using .mdf in visual studio 2005 using vb.net (Windows XP sp2)
The app runs fine on the local machine. But I want to access the database from another computer (remote connection)
My Questions:
1. How to host the database file (mydb.mdf) on server machine?
2. How does connection string change on the client side?
Any other idea?
THanks!!

Good day.
I am trying to look at a friends database that they have developed. Not having used SQL Server Express before I am experiencing problems trying to remotely connect to their database.
He connects locally just fine of course.
I get the error message about remote connectionsand the default settings so I have enabled TCP/IP and Named Pipes as well as cleared SQLSERVER Express in my firewall settings. I also stopped and restarted the service, but still get the same error message.
My connection parameters are like:
Server type: Database Engine
Server name: http://sql.exampledatabase.net (should http be here? have tried with and without same error)
Authentication: SQL Server Authentication (windows authentication? If so, how do I change to such?)
Login: http://username (should http be here? have tried with and without same error)
Password: password
TITLE: Connect to Server
------------------------------
Cannot connect to http://sql.exampledatabase.net
ADDITIONAL INFORMATION:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
Any help would be much appreciated.

I have Microsoft SQL express server 2005 setup on one server and I have a website setup on another server, I am trying to get some data from the SQL server on the other one.
I am currently getting this error: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not 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 have done plenty of searching on Google, and already been through the tutorial on changing the setting in ‘SQL Server 2005 Surface Area Configuration’ to allow remote connections
http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspxhttp://support.microsoft.com/default.aspx?scid=kb;EN-US;914277
It works perfectly when I call data from my local machine.
Also I don’t know if it is a timeout issue, because I tested in on two other servers I have access to and it worked on one of them.
Any help would be very much appreciated.
Thanks in advance.

I followed the steps outlined in a blog I found to setup SS2005 express for remote connections. Everything appeared to go smooth until I actually tried to logon ;)
I have Sql Server 2005 Express installed on my WinXP PRO machine at home (no domain). I have opened the ports on the firewall, etc.
When I try and login from the SQLCMD command line tool I get a Login Failed error. Here is the connection string that I'm trying to use:
SQLCMD -S **.***.**.*SQLEXPRESS -U Steve -P MyPassword
The error:
Login failed for user 'Steve'.
When I use Management Studio Express on the same machine running Sql Server, it shows the User name: NEVERSTILLSteve
'NEVERSTILL' is the name of my computer.
If I try and use that same username with a remote connection I get the same error.
I have googled for the error and msg code, but nothing fitting my situation is coming up.
Anyone have any ideas for me?

Hello,
2 weeks ago, I installed a SQL Server 2005 Express on one of my computer. I fought to configure the remote access, but finnaly it did work.
Yesterday I had to move my server on another computer and I've never succeeded in configuring the remote access. I don't understand why it is so complicated to install remote access.
I explain you what I did, and if you could say me what i missed, it could be amazing !!
I install SQL Server 2005 Express including the SQL Server Management Studio Express.
I went to the SQL Server surface area configuration and i enable Remote Access (TCP) and turn on the SQL Browser
I enabled Server authentication => SQL Server and Windows Authentication mode.
I created users with all the permission i can give to them.
I restart one million time all the services and nothing...I tried to connect to the database using my local Microsoft SQL Server Management Studio Express, using the Visual studio Sever Explorer and with C# script using this connection string :
sConnectionString = " Server=myIP\SQLEXPRESS; Initial Catalog='myDatabase'; user id = myLogin; password = myPassword";
And I've never succeeded in connecting, I have always the same error :
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)which means the database is not reached.
Please tell me i've just missed a stupid thing.

Hi,
I want to make a component library in Visual Basic.NET and connect to a remote Sql Server. When I create a new DataSet with the wizard, I can only connect to a .mdf file, but not to a Sql Server. With Visual Web Developer I can connect to a Sql server. What is the difference between these enviroments ? How can I do the same with Visual Basic.NET ?
Thanks in advance.

Hey all!
I've tried all I know in an effort to get SQL 2005 Express to allow remote connections on my customer's 2K3 server and I'm not having any luck. I've followed MSKB 914277, including adding the exceptions to their Windows firewall...even disabled the firewall altogether (for testing purposes), and I still can't get remote clients to connect. As suggested by various other posts, I used netstat -an to confirm that SQL is listening on port 1433 for the desired IP on the server.....and saw that it is listening. Here's a snippet:
TCP 192.168.0.2:1433 0.0.0.0:0 LISTENING
TCP 192.168.0.2:1433 192.168.0.2:1738 ESTABLISHED
TCP 192.168.0.2:1738 192.168.0.2:1433 ESTABLISHED
TCP 127.0.0.1:1433 0.0.0.0:0 LISTENING
I can connect to the database locally (i.e. on the 2K3 server itself) using just the IP address .... tried with a DSN, UDL, ODBC, and SSMSE...all of which have no problems (as shown by the two, "ESTABLISHED" entries in the netstat results above which were from running SSMSE locally on the server at the time of the netstat). But if a remote computer on the network tries to connect, they cannot connect. Sorry, I don't have a copy of the error message the clients are getting yet.
I asked The customer's IT to confirm that the clients CAN can "see" the server (i.e. that there wasn't some kind of router or firewall blocking their path) and they sent me a copy of the server's pfirewall.log file. Here is an entry from the file that seems to show that client requests ARE getting to the server:
2007-12-17 19:12:13 OPEN-INBOUND TCP 192.168.0.4 192.168.0.2 1213 1433 - - - - - - - - -
2007-12-17 19:12:13 CLOSE TCP 192.168.0.2 192.168.0.4 1433 1213 - - - - - - - - -
I'm starting to get in over my head here (I'm a programmer, not a DBA or Net Admin), but doesn't the above suggest that an incoming request came in from .4 on port 1213 and attempted to connect to .2 on port 1433, but the connection was denied or dropped by the server? If so, why? Is this related to another MS KB I read about connection pooling? I'm way over my head here and could use some help. Did I miss something subtle during configuration of SQL Express?
Thanks in advance.

Hi ,
After reading the SQLexpress weblog , I tried the solution and its still not working
http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx
The client computer gives me this:
Run-Time error -2147217843 (80040e4d)
Log-in failed for user "KitGuest"
The connection string in the ADO object in my testing VB6 program is:
my_connection.ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;User ID=kit;Initial Catalog=AdelaideMushroom;Data Source=KITSQLEXPRESS"
I am confused with the error massage as my conncection string is set to connect on UserID = Kit
I am not sure what is gone wrong. The same VB6 program runs perfectly on host machine
I am not sure is there anything to do with SQL Config. Manager's SQL server 2005 service's Log-ON setting:
Log On as - Build-in account: Network service
could Anyone who managed to get remote connection work give me some advise?? I am desperate. have read that weblog many times and do not know how to get it work

Hi
have sql server express 2005 installed on a laptop running XP sp2 with IIS installed. installed sql express during the visual studio 2005 install
having problems with remote connection errors messages when using aspnet_regsql.exe as well as when trying to view pages with sql db involved. in most tests to fix this i disable my firewall, still getting error messages tho
sqlBrowser is running as is sqlexpress in services both on auto
in the surface area configuration tool, the remote connection is set to local and remote connections is using both tcp/ip and named pipes.
in sql config manager- shared memory, tcp/ip, and named pipes are enabled for both the server and the client, the order on the client is shared memory then tcp/ip then named pipes
inside the server's tcp/ip on the ip tab, IP1 is set to active, enabled, the ip address is 192.168.1.41 which is different from the laptop ip (192.168.1.39), there is no port number for IP1, should there be a port number?? dynamic port is 0
IP2 is set to active, enable with address 127.0.0.1 and also does not have a port number, dynamic port is 0
IPAll is using dynamic port 1232 but also has no port number.
for the client TCP/IP setting the default port is 1433 and it is also enabled.
also downloaded and intalled SSMS-EE and under properties for the sql server >connection, the allow remote connection box is checked. I am using the default instance sqlexpress, there is another instance microsoftbcm (what is that??) and it also has the allow remote connection box checked.
server security is set to windows authentication
keep getting

I am new to VB.Net coming from a VB6 background using the VB.Net Express and have even loaded the SQL Express. The learning curve is not to bad until you get to dealing with connecting to db's. However, in trying to fill a grid with data, manipulate it and then update it has not been any fun either. There does not seem to be enough information out there dealing with these two as of right now.
Anyway, trying to add a datasource connection for a grid has resulted in a real problem even using the connection wizard. I keep getting the same error that the default settings for SQL express does not allow remote connections. However, I thought that I have corrected that. Unfortunately, with VB express I cannot even seem to talk to my SQL 2000 server either because it gives me the same exact error. I am thoroughly frustrated with it and ready to just do it in VB6.
I am open to any thoughts on this. I do not like using bound controls, except in a few situations. I would like to create it unbound if at all possible. If someone could give me some ideas as to what to do and where to go with this I would appreciate the help. I have been doing a lot of reading and a descent understanding what is needed to talk to a SQL db.
Thanks in advance.

I get the following error and have been trying to figure out why I keep getting it. Initially, I had placed my project under wwwroot folder and ran it under IIS and it gave this error. Then I moved it to my local C drive and same thing. I am sharing this project with two other co-workers and all our config files and code files are same...they don't get this error but I do. I checked that SQL Server Client Network Utility has TCP/IP and the 'Named Pipes' enabled. I thought maybe I have setting in the Visual Studio 2005 that I'm not aware of that's causing this problem...it can't be the server since my co-workers aren't having this error and can't be anything in the code since all of us are sharing this project through vss. I dont' think using different version of .net framework can create this error. I changed the version from 2.0 to use 1.1x and it gave same error... Any help would be greatly appreciated. Thanks in advance.

Hello. I am called Narsiste.
I have a problem of configuration in SQL server 2005 express train. In fact, I do not know how to make the configuration to tackle the databases SQL server 2005 express train which are on a station has starting from a station B (both being in a network LAN).
But I read in the module of €œconfiguration of the surface of exposure for the services and connections - localhost€? that €œBy defect, the editions Express train, Evaluation and Developer SQL SERVER 2005 authorize only local connections.€?. As it is BY DEFECT, I said myself that it will have to be changed a parameter so that access TCP/IP can go on this version of SQL SERVER.
Here is the message which I have:
€œAn error occurred during the establishment of a connection to the waiter. At the time of connection to SQL Server 2005, this failure can be due to the fact that the default settings of SQL Server do not authorize remote connections. (Provider: Interfaces network SQL, error: 26 - Error during the localization of the waiter/the authority specified) (Microsoft SQL Server, Error: -1)€?.
If somebody encountered this problem in the past, that he wants to inform well me of the solution which he found for this last. Thank you.

Hi. Im trying to get a asp.net web aplication to write data to an sql express server located on another server. However when i try to connect with VS 2008 it says: "Named pipes provider, error 40: - Could not open a connection to SQL server".
What do i need to do to get this to work. Do i have to set something in the sql server, and i assume i have to open some ports in my firewall aswell?
Any help sugestions would be aprichiated

I am currently using a Microsoft Access (MDB) for my application. But I am looking at allowing other users on the network access the same database -- I know a Microsoft Access database is not the best solutuon for this enviroment.
I'd like to use SQL Server 2005 Express in this case. I am very fimilular with SQL Server 2000 Std/Ent editions. My question is, can I use the free SQL Server 2005 Express edition and allow remote users to connect to that database? Or is it supposed to only be used as a local database accessed by only the machine it's installed on?
Thanks,
Jason

I've developed an asp.net 2.0 web app with vs 2005 and am using a SQL Server 2005 Express database. The app works fine locally, but after uploading to the remote web server the following error occures:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
How do I go about granting remote connections to SQL Server Express?
Does the web server have to have SQL Server Express installed in order to run apps that utilize SQL Server 2005 Express databases?
Do I grant access locally on my machine or do I have to be on the web server to grant remote connections?
I've been using .net 1.1 with access databases for the past couple of years, so this is all new to me.
Thanks.

I'm using SQL Server 2005 Express, Windows XP SP2. I connect using Windows authentication.
The data source that I'm trying to hit is on a remote server. It's an OpenLink ODBC Data source, and the server is in another location. SQL Server 2005 Express and the ODBC connection are both installed/configured locally on my machine.
I can connect to the remote server. The DSN exists as a System DSN.
The DSN has its own proprietary configuration utility, which I can configure so that the server name is XPLILLEYGSQLEXPRESS. The configuration utility doesn't care; I connect successfully one way or the other.
When I open Management Studio Express, I can see my database (CMS) listed under the "Databases" folder, but there's no tables in there, other than the system tables.
So my question is, what am I missing?
Thanks

Hello. I have SQLEXPRESS 2005 installed on my laptop running Windows XP Home Edition with SP2. I have an application that can connect to the local instance with no problem. The other day, I tried to configure SQLEXPRESS 2005 for a remote connection from my desktop. To date, I have been unable to figure out how to do this.
I have followed the instructions posted at various locations on the internet, but to no avail. While I can configure SQLEXPRESS 2005 to allow TCP/IP connections, I have been unable to restart the server.
Here is the pertinent snippet from the error log:
<time> Server A self-generated certificate was successfully loaded for encryption.
<time> Server Error: 26024, Severity: 16, State: 1.
2006-08-14 21:02:27.18 Server Server failed to listen on 'any' <ipv4> 0. Error: 0x277a. To proceed, notify your system administrator.
<time> Server Error: 17182, Severity: 16, State: 1.
<time> Server TDSSNIClient initialization failed with error 0x277a, status code 0xa.
<time> Server Error: 17182, Severity: 16, State: 1.
<time> Server TDSSNIClient initialization failed with error 0x277a, status code 0x1.
<time> Server Error: 17826, Severity: 18, State: 3.
<time> Server Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log.
<time> Server Error: 17120, Severity: 16, State: 1.
<time> Server SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.
I have a feeling this problem is due to the way my system is configured, not necessarily how my SQLEXPRESS 2005 is configured. My laptop and desktop are connected via a wireless router, and both machines are running Norton Anti-Virus 2006. I've added sqlserver.exe and sqlbrowser.exe to the exceptions list for the Worm protection on the laptop, i.e., the server machine. There's not a setting at the router that would prevent the server from re-starting, is there?
Any help is GREATLY appreciated!

Hi --- I would like a few users to be query tables, run (create ?) stored procedures, etc. on a SQL 2005 Workgroup database (the sql server is on a dedicated server)...
Will the Toolkit version (or any other version) support this?
Thanks!

I want to connect to that database remotely from my machine using VS 2005 or Management Studio....both are encountering the same problems.....
On the Virtual Dedicated machine if I install management studio I run has no problem....it asks me for the server name : somethingSQLEXPRESS then username and password and works fine...
The same thing I try to do remotely is not happy with ....I tried to give the IP address of the server same thing no luck.....
Can somebody tell me what I'm doing wrong and where....
