I have an application that will deployed on LANS running 1- 10 systems on average.
The front end is C#.net 2.0 and the backend will be sql express.
I need to enable remote connections by default because 99.5% of our customers have 2 or more computers.
I have two questions:
1) How do I enabled remote access during installation? Can I run the sqlExpress install silently and turn this on so that my users (who are very non-technical) do not have to go into surface configuration and turn on network access?
2) If I already have sql express installed (like on my development machine now) how do I enable remote access via a command line utility without having to run the surface configuration tool? I want to be able to execute a command to turn on network access so my users don't have to go to a GUI tool(Surface area configuration) and turn it on themselves. Can I use sqlcmd to turn on network access or some other command line utility that I can execute easily. Perhaps there is some type of .NET assembly that I can reference from within my C#.net application that will allow me to enable remote access? Basically How do i take care of this without making my users have to do it?
I am trying to create an un-attended SQL 2005 Express install. I have successfully made my own template.ini file to install SQL the way I like but I cannot find a way to make it install with the "Ad hox remote queries" option enabled.
Is there anyway to do this? I can't seem to find any switches in the INI file to allow this.
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:

I am a new Microsoft VS.NET Express user to do the SQL Server 2005 Express and VB 2005 Express programming by using the example of a tutorial book. Please help and tell me what is wrong in my SQLCLR sep-up and project coding and how to correct the problems.
I am running a standalone WinXP SP2 system with VS 8 and SS 5 Express on it. I have been working very nicely with VB and SSCE, but I want to learn to use Sql Server 5 Express, which I also have on my system from a prior install of VS 5. I am strictly doing this as a learning experience on my own.
I have been trying to install the NW sample database into SS 5 Ex, but it is obviously not configured properly, because I am getting errors stating that the scripts cannot install because they cannot establish a remote connection to SS. So I looked up the FAQ item here on setting up for remote connections (which I am not even sure applies for a standalone system like mine). Anyway, I followed the instructions in the FAQ, using the SAC util to configure for remote connections, but it does not work. Every time I try to start the DB engine, it fails with the following message:
When trying to start Database Engine when configuiriung for remote connections in SAC:
"TITLE: Surface Area Configuration ------------------------------ The service did not respond to the start or control request in a timely fashion, you need administrator privileges to be able to start/stop this service. (SQLSAC)
Now, I am the admin user on the PC but OK, so I selected the SAC option to set myself as SSadmin, even though this option is supposedly only for Vista users according to the dialog. Anyway, it does not allow me to set myself as SSAdmin, it returns the following error:
When trying to add myself to SQLSAC, even though it is for Vista:
"TITLE: .Net SqlClient Data Provider ------------------------------ 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) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtI D=2&LinkId=20476"
(which help link is no help BTW, because it is not valid). And the setting does not get set, because the next time I open that dialog, I am back to being a non-admin user.
So what is the solution here? Am I going to be able to use SS 5 Ex on my PC? No matter which connection option I select, either local only, or for any of the remote options, I cannot get it to work. Am I supposed to reboot my PC after changing a setting? Or is it just not possible to run SS 5 Ex on a standalone PC like mine?
Or worse, are there a bunch of other configuration settings I must change as well? I note that, when I look in the SS Config Manager at the properties for SS Express, I see that it shows the logon option that uses the built-in account "Network Service"rather than Local System or Local Service; is that correct? BTW the browser is always running in all this.
As you may gather, I know zip nada about SS, but I am an experienced VB/VBA/VC+/FP programmer of many years, did desktop Access databases w/VB6 frontends for a lot of customers, so I am familiar with DB design etc. I just know next to nothing about backend stuff like this, other than a little with BTrieve years ago.
Hi, My Web Aplication read and write into a sql server express database. The database is in one server and the applicacion is running from my laptop. Everything works well. But if i publish the web in the same server that the sql server and getting the next 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) When am running the application from my laptop i am using the external IP and when I publish it in the same server i am changing the IP for the server name. The most interesting part is that the web can read but when it tries to insert is when am getting this error. Any clue??' I can select, delete, insert using Microsoft SQl Server management Studio from my laptop, then the sql server accept remote connections. I do not understand why the ASP.Net application works perfectly when runs from my computer but get this error when is publish in the server. Any help will be more than appreciate. Thanks in advance
My target market includes Micro-SMEs (i.e. 1 to 2 person business). This users often have multiple computers, but tend to run XP Home edition. Hence I need to set up a SQL Server Express on one of the machines and allow the other machines to access it.
So far I realise:
XP machines must be SP2ed (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=379560&SiteID=1) XP Home machines need to be in the same work group (am I right?) I have to Open up the MS Firewall on each of the machines for TCP ports 1433 and 1434 (see http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=511441&SiteID=1) On the machine hosting the SQL Server Express instance, start the "Browser" Service (again http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=511441&SiteID=1)
I have several questions surrounding this.....
If I package SQL Express with my application is there away I can get the Browser to be started automatically? Do I need to write some custom code using the Microsoft.SqlServer.Management namespace? My understanding of the SQL Server security model is that ideally I should ideally use Windows Authenticated users connections - how do I set up the remote XP Home user on the XP Home machine which is hosting the SQL Server Instance? I'm thing I may have to used Mixed Mode and pass the SQL Server username and password in the connection string. Am I right or can I use Windows Authenticated? Are there any more resources other than http://msdn.microsoft.com/sql/express/default.aspx?pull=/library/en-us/dnsse/html/emsqlexcustapp.asp which I should look at for help on installing an app bound to SQL Server Express?
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.
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.

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?
I have a customer who is looking to encrypt their applications connection to the back-end SQL server. I've gotten a valid certificate for the server from a trusted CA, and it's installed on the server (shows up in Personal certificates in the Certificate MMC when selecting the computer) and I can choose it in the drop down on the certificates tab of the SQL Network protocols properties in Configuration Manager.
Now, my question: If I select the certificate but do NOT enable the "Force Encryption" option, the client will be able to request encryption on their end, and the connection will then be encrypted. If the client (other applications) do NOT request encryption, they will still be able to connect, but their connection will be un-encrypted. URL....
Lastly, I could've swore I had found some information indicating that some methods of establishing a connection to SQL can fail when Force Encryption is enabled, as the method doesn't support SSL encryption.
Fellow Devs, I have an instance of SQL Server Express 2005 running on another box and I have Remote Connections enabled over both TCP/IP and Named Pipes, but on my other box I keep getting the error that the server does not accept Remote Connections. Any ideas why this might be happening? Is there some other configuration?
HiI'm going insane.I have a club starter kit on my local server which is working fine.I have migrated the database to my remote host and seems to have transfered ok.For a brief period I was able to connect to the database remotely, but now I cannot I get the following, even though SQL Server Surface Area Config is set to accept remote connections.An error has occurred while establishing a connection to the server.

Hi,I have SQL Server Express Edition. I tried working out some ASP.NET Labs in my local system. Here is the link of the Virtual Lab which I tried. http://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?EventID=1032286906&EventCategory=3&culture=en-US&CountryCode=USI recieve this error in my local system.

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)I tried working out solutions from various websites. But the no solution is effective. Could anyone help me in solving this issue.
Does someone have a guide or a link to a guide to allow remote connections from a default install?
Just that I'm currently testing my setup on a work laptop but not having much success but thats probably down to the network admins limiting me far too much on here.
However I am getting a new DELL machine, which I'm gonna make sure the network admins get no where near. Once I have this machine I will be forwarding port 1433 to the machine, but need to know what other changes I need to make to allow my friend access to the machine as well.
So I'd need to know what server settings I need to change and also what my friend needs to do as a client.
While trying to transfer my website project to another computer I am encountering an error when tryng to run the solution. It gives me a "Does not allow remote connections". Why is this when on the original computer everything worked fine.
Hi folks,Perhaps every 100 calls to DB i get 1 error message like this:"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)" i am using SQL 2000 and am wondering why this happens.I appreciate your help.Leo.
I am getting the following connection 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)When I run the page locally on my develepment environment, the page runs fine. I'm using VS2005 and SQL Server Management Studio Express.When I upload the page to the remote server, I get the connection error indicated above.To further troubleshoot the issue, I created a simple test page with the connection string hardcoded in the code-behind and binded to a dropdownlist using the following code:SqlConnection conn = new SqlConnection("Data Source=xxx.xxx.xxx.xx;network=DBMSSOCN;Initial Catalog=TechCenter;Persist Security Info=True;User ID=xxxxx;Password=xxxxxrx;Asynchronous Processing=True;MultipleActiveResultSets=True"); conn.Open(); SqlDataReader dr; SqlCommand command = new SqlCommand("SELECT RecordID, customer_id FROM Customers WHERE recordtype <> 'F' ORDER BY customer_id ASC", conn); dr = command.ExecuteReader(); while (dr.Read()) { DropDownList1.Items.Add(new ListItem(dr["customer_id"].ToString(), dr["RecordID"].ToString())); } dr.Close(); conn.Close();When I run the test page, it works fine, so I know I'm using the correct connection string properties.When I move the connection string to the web.config file and using a dataset with a tableadapter, I get the error about the sql server not allowing remote connections? I'm stumped. I cannot isolate the cause of the error.The remote server is using sql server 2000 and error indicates it is trying to connect to SQL Server 2005??? Any help would be greatly appreciated.Thank you.
I have a need to connect to a remote (i.e. database on the clients site) SQL Server database from a live application. It is relatively easy under Oracle, but I havent tried to do to an SQL Server. Has anyone done this? The remote SQL Server database in question is 6.5 You can set up odbc connections to remote clients (99% sure on this) so you could go this way. You can also connect directly to a sql box through an IP address in sql7, but I am not too sure how it is with 6.5.
I installed full version of SqlServer 2005. Iam able to Connect to all the systems that are in Intranet. But iam not able to Connect to the external systems (or) remote Connections. I followed all the steps that are in the following URL support.microsoft.com/kb/914277 Still iam getting the problem. Show me a way in this issue.
The problem is that we are having Problem while making the remote Connection to the Sql Server 2005
Basically We are having a problem connecting to SQL2005 through a package remotely. when we try to connect to a remote data base, we get the following error
[Connection manager "CRA LRRS Development DB"] Error: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Login timeout expired". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "An error has occurred while establishing a connection to the server.

Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. ".
Although by running the configuration manager on the Remote DataBase System we have enable the Remote Connections through name and IP both but still it cant access it.
Please tell us the possible consequences and provide us the feedback.
I will be really obliged if any of you can provide us the feedback on it as soon as possible.
I am having trouble with Report Manager. It seems that every day or every other day we get this message:
"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 - No such host is known.) 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."
To fix this we open the Surface Area Configuration for the server that hosts the Reporting Database and stop and restart the database engine then open up the Surface Area Configuration for the server that hosts the Report Manger database and stop and restart that database engine along with the Reporting Services Browser.
This actually may not be the exact order that we do the stop/starts because we have tried so many different combinations (ie. stop one then start another then restart that one, etc.). Anyway, we usually keep on stoping and restarting until we can get back into Report Manager without getting the error message from above.
Does anyone have any insight as to what this could be??

I have recieved this error and i have changed the surface area configuration to allow remote connections but it still won't allow them after i start and restart the server service. is there any way to fix this i have reinstalled several times and that has not yet fixed the problem either.
This question has probably been asked a few times on the forum but none of the answers work for my situation.
I recently installed SQL Server 2005. When trying to connect to my server, locally, using Management studio, I get the following 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53).
I have already enabled remote connections in the Surface Area Configuration, using TCP/IP and pipes. I created exceptions in the Firewall and started the Server Browser service.
I downloaded VS studio express, and created a personal website using the wizard to test drive the thing. When I hit ctr + f5 to run the sample provided, then I get this message:
"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.

I tried disabling the firewall (Norton's firewall because Windows is disable always). Any suggestions? This is a brand-new machine, running XP sp2, just downloaded the VS studio express.
