SQL Server 2005 doesn't take remote Connections by default
I'm playing around with IIS7 today and I have a separate machine set up to check out a few of my existing applications both ASP.NET and a number of Web Connection ISAPI applications. It took a bit to get the server up and running but all went well after some tweaks.
The real head scratcher occurred though because I couldn't connect to SQL Server on my development laptop. I've recently installed SQL 2005 on this machine and I've been happily plugging away with it on my local machine for a few weeks now. While it works fine locally today I couldn't get it to connect remotely from the IIS7 box.
Eventually after a timeout delay I ended up with a connection error message that says:
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: 2)
A couple of searches through the Properties of the server didn't show anything refusing connections – the connection count is set to 0 (unlimited connections) and this would be the logical spot to find an option that refuses connections, right?
Well, it turns out that this is controlled by an EXTERNAL utility, the Sql Server Surface Area Configuration Tool which can be found in Start Menu Sql Server Configuration section. By default Sql 2005 indeed refuses remote connections and you need to run this utility to enable remote connections. Intuitive isn't it?
Is this really necessary? Disabling remote connections on a SQL Server by default seems a little odd anyway. I mean it's a SERVER isn't it? Who's not going to want to have remote connections on this thing? At least add the option to the server itself in a logical place and even if you can't set it there give an indication that it's disabled elsewhere…
But no – we're too paranoid. If connections were disabled in the server itself somebody could hack that – yeah right...
This security stuff is really going a few steps too far. In Vista EVERYTHING pops up security permission dialogs because practically nothing including the native Windows Applications are signed. It looks like everything will have to be signed in order to not pop up permissions dialogs. This is a small vendor's nightmare – getting a verified signature is a pain in the ass and if that ends up being a similar process as it was with ActiveX controls we can look forward to the same mess where nothing is signed and everybody blindly clicks Ok… doesn't that sound like fun
Well the upside is my app is running with remote data now on IIS 7 which is nice. Next is hooking up some of the optional modules and see how they fare in the integrated pipeline...

# re: SQL Server 2005 doesn't take remote Connections by default
And people wonder why I still use W2K and SQL Server 2000...
# re: SQL Server 2005 doesn't take remote Connections by default
But ya, it does seem like we're going from one extreme (Win 3.1 = wide open) to the other extreme of wicked lock down.
re Vista
It'll be interesting to see how VisualStudio acts on Vista?! :>
# re: SQL Server 2005 doesn't take remote Connections by default
I would hate to see such a similar feature in an ahem... open-source project that would require editing a massive config file...
This security paranoia is utterly stupid and annoying. And now, with vista and HD media, it's getting even worse!
Hey MS: Secure your damned products in first place, don't postpone bug fixing!

You can't even install the sample OLAP dB due to
this issue. Give me a break!
Thanks for the info

You have a group of engineers that end up running <insert favorite app here>. (I for one have installed programs to try them out, and then promptly forgot about them)...
Fast Forward...a bug is discovered that exploits said app by connecting to it and using it to propogate
Would you rather be in the position of having to lock down the machines with the software on it, or have it locked down by default...

It is sql server 2000 and not 2005. but due to my Studio 2005 some setting is changed. Any solutions ?

Damn, I just got the same problem on my XP-VS05 trying to connect to SQL 2000 via ado.net/asp.net. I tried the SQL analyzer and it worked fine except in asp.net. But it also work a few days ago in my ASP.net all sudden it stopped. :(

My set up is Windows Server 2003, Visual Studio 2005 and SQL Server 2005.
NOTE WHAT I HAVE FOR THE SERVER "STEVE1\\STEVE"
SqlConnection cn = new SqlConnection("Server=STEVE1\\STEVE;Initial Catalog=AdventureWorks;UID=foo; password=foobarite;");
Hope this helps others :)
# re: SQL Server 2005 doesn't take remote Connections by default
My machine is called STEVE1
My SQL Server instance is called STEVE
Sorry that I did not get this into the original message.

I have trawled the net and spent countless hours on MSDN and many have tried to help. I have changed the passwords to strongly typed... I have recreated the login a zillion times,mapped to different databases , checked firewall settings, switched off firewall...tried different database roles, run every possible sp I can find.....attached the database using the connection string, attached using management studio and changing the connection string back, tried every possible connection string I can find, pored through the logs at evry turn ...
Then i did it all again and again and again.
Has anybody managed to connect from an application ever.. (excuse the cynicysm but I am at wits end)
The best error has to be this one proclaiming success and failure all at the same time:
2006-11-28 22:00:24.46 Logon Login succeeded for user 'FJUser'. Connection: non-trusted. [CLIENT: 192.xxx.x.x]
2006-11-28 22:00:24.46 Logon Error: 18456, Severity: 14, State: 16.
2006-11-28 22:00:24.46 Logon Login failed for user 'FJUser'. [CLIENT: 192.xxx.x.x]
Makes my confusion a little more bearable :-)

I've followed all of the advice posted on this site and many others; however I cannot get my server to allow remote connections. When installing, I created a named instance called SQL2005, instead of allowing SQL to just create a default instance. I don't know if this is correct or not?
My error message is: "An error 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 open a connection to SQL Server) (Microsoft SQL Server, Error: 2)
In any case, please, if anyone out there knows how to configure SQL Server 2005 to allow remote connections it'll be greatly appreciated.
Thanks,
Colin.

run "cliconfg"
click on "Alias" - make sure you do not have a named pipe alias created for the SQL server that you are connecting from the ASP app.
Happy coding..

Slammer worm anyone?
Still to this day there are port scans against sql server 2000 and 7. No company can have a perfect record with security, and it's dare I say intellegent to not have your server be able to be connected to any machine in the world on initial install. Installing a "new' install of sql 2000 "Gold" edition would get "hacked" nearly instantly if given a public IP and no firewall blocking incoming traffic in place (again causing the same thing this article complains about..no remote connection out of the box).
EVERY open source database that I've ever used follows this common sense approach of not allowing remote connections to every IP by default (btw searching that big massive config file for 127.0.0.1 usually brings you to the right line, for those of you who are scared of such things).
I commend Microsoft for doing the same, sure they could make it more intiutive to just find, but I welcome anyone using any server product with a lot of features (read: able to be exploited badly) to read deployment guides and get to know what they're doing first.
Microsoft has fabulous documentation about its core products, I think its a shame that people would rather poke around a UI for days on end instead of using well written resources such at these:
http://www.microsoft.com/technet/prodtechnol/sql/bestpractice/default.mspx
There are several links in the above that show how to allow remote connections to SQL Server, some white papers are newer admittedly than this article but most of those are just new incarnations of a gold or sp1 paper with sp2 changes.
I'm glad for the new security focus from Microsoft..and I'm sure that all the people complaining about how things are now, were complaining about slammer, nimda, or code red (iis vunerabilities i know for the last two), are the ones who complain about the default behaviors now that help prevent such awful outbreaks.

Go to SQL server Configuration Manager under Configuration Tools, press once SQL Server Services, in the right pane you will get SQL services Right click on SQL Server (MSSQLSERVER) and Start.
