Server Was Unable To Process Request. ---&> A Connection Was Successfully Established With The Server, But Then An Error Occurred During The Pre-login Handshake.
Apr 16, 2008
I got this message from sql
"Server was unable to process request. ---> A connection was successfully established with the server, but then an error occurred during the pre-login handshake. 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 - An existing connection was forcibly closed by the remote host.) "
Does anyone know what happen?
Thanks

Hi,
I am having such a problem. I have SQL Express installed on the windows 2003 server and originally I installed instance1 of SQL Server 2005. When I installed Instance1, I remember having problems with remotely connecting to that instance1, but somehow I fixed it. Now I installed instance2 and I started having remote connection issues again with that instance2. I am able to connect to instance1 but not instance2. I checked settings for both instances and they look identical.
I turned firewall off for now. I checked TCP settings using surface area configuration (allowing both local and remote connections). I turned off VIA protocol. I specified TCP properties to use dynamic port for that instance2.
In the sql native client configuration I have the following order#: 1. Shared memory, 2. tcp, 3. np, 4. VIA(Disabled). TCP is configured to use 1433.
I have no clue about what is going on. Sometimes I am able to connect remotely and sometimes I get the following error:
"A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The specified network name is no longer available.) (.Net SqlClient Data Provider)."
When I connect locally - everything connects fine. File sharing is also checked, it works etc...
Thanks for help!!!
GK
I just noticed that I was able to connect from different computer on the different network.

I have just installed MS SQL Server 2005 Express edition along with the SSMSE. I am using windows authentication. When I open SSMSE it connects me to a 'local instance' of the server. From there I right click on Database and select to add a new Database and I get the error above. I think I only need to allow local connections to the engine but I have tried allowing remote conections with all varations of named pipes and TCP/IP. I am running on Windows XP SP2 (home).

i'm going nuts with SQL server notification thing. I have gone throigh this artical which tells how to set user http://www.codeproject.com/KB/database/SqlDependencyPermissions.aspx. This article show how to create new user and setup for sql server notification.But In my case user was alredy existing in database. which is very common senario in most cases. So i did following( check the SQL script below) but then i get this error
"A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)"
this my sql script
use [master]Go

-- Switching to our databaseuse [DatabaseName]GO
CREATE SCHEMA schemaname AUTHORIZATION usernameGO
ALTER USER username WITH DEFAULT_SCHEMA = schemaname GO

I get the following error approx once per week(not at the same day/time) when logging into our site:-
"a connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error : 0 - SSL Provider: )"
It's on SQL 2000 & Windows 2000.
It's a test server with very little traffic. At the moment an IISRESET allows access to the site again until 5 - 7 days later when the problem appears again.
Any ideas ?

Hello
I am getting this err msg when trying to logon to my website on the web - on my machine there is no prob,
An error occurred while established a connection to the server.
When connection to Sql.S 2005, this failure may be caused by the fact that
under the default settings sql.s doesn't allow remote connection.
(provider ql.S Network interface, error:26- Error Location Server/Interface Specified)
(the files path is like in the web host s)
now this msg is related to the ASPNETDB.MDF (dont use sql.s db but this file)
thanks

Hi,
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
I am using a direct connection from my Gridview to perform a huge database search. the stored procedure will take 10- 60 seconds to execute the query.

Hi all,
I am new to SQL 2005. I have one issue and it is as follows:
I write a simple query and run it; it works fine.
Now I break the network connection and run the query; in this case it runs fine.
But when I reconnect the network and run the query, then I get an error as follows:
"A transport-level error has occurred when sending the request to the server. (provider: Named Pipes Provider, error: 0 - An unexpected network error occurred.) "
Every thing is local here. So how the network issue comes here?

I've tried to search on the web for a solution for this error but i didn't find any working solutions for this problem. We have 2 servers. The first one is the server we use to develop our ASP.NET 2 application. On this server we don't have this error. On the other server (use by our client) we have this error sometime and i don't know why. Both servers have the same configuration and both application have the same web.config file.
I've tried to add a try-catch and retry the query when the error occured. This seems to be working but we don't want to have to change all our connections and since we don't have this problem on the other server we want to find the source of the problem.
Any idea ?
Thanks !

Hi,I need some help. I am getting this error after I complete the asp.net register control and click on the continue button. It crashed when it tries to get it calls this Profile property((string)(this.GetPropertyValue("Address1")));When I look at the stack, it is coming from my ProfileWrapper class which adds user address, city, etc.. from a class which inherits fromSystem.Web.Profile.ProfileBase. From the stack, it is calling the System.Web.Profile and crashed when it tries to open a connection atSystem.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject). I already migrated all aspnet_user, aspnet_roles, etc.. and don't get any connection errors. It is only when I try to get the profile data. This works on my pc, but throws an error on my lunarpage website.Any help is greatly appreciated.Thanks,AJAn error has occurred while establishing a connection to the server.

My site works fine in VWD2008 express, but I get this error when I try to use it on my live website.
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.
According to this article: http://support.microsoft.com/kb/914277 I am supposed to:
1.
Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
Ok, there is no such program in this folder. The only thing in there is "SQL Server Error and Usage Reporting"...
The other thing I am greatly concerned with is this: All is want is for my webpages to be able to access my database for user authentication. I DO NOT want to grant the internet rights to remote connect to my database.

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.

I use Microsoft Windows Vista Home Professional
I have already installed to my computer Microsoft SQL Server 2005 and SQL Serves Express. I used to be successful to connect to the SQL Server but now I CAN NOT.
Not: I try to run SQL Server 2005 but I can not, even I logged on to my computer with an administrator rights. On the other hand I can start and stop the SQL Server Express easily.
As a result, how can I solve this problem.
Thanks in advance.

I don't know if it's something to worry about, since I haven't had anyone call in an issue.
I have set the default and named instances to specific ports, no dynamic ports here.
There's nothing in the instances' error logs.

Hi i get this error when i try to connect to my database through my web application "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)". This is the connection string in the web config file if it helps;<connectionStrings>
<add name="strConnectionString" connectionString="Data Source=itmrwks001;Initial Catalog=DHOC;Integrated Security=True; Trusted_Connection=Yes"providerName="System.Data.SqlClient" />
</connectionStrings>
Where am i going wrong, thank you.

Hello,
I'm having trouble getting my Sql connections working 100%. My pages usually connect ok, but sometimes for a reason I can't understand I get connection errors. I always use the connection string in web.config so there's only one connection string for the whole project.
I can be on one page, do nothing and just press F5, usually it works but sometimes it doesn't. It just throws this error. I've checked the surface area configuration and tcp/ip is of course allowed remotely. The weird thing is that it only happens sometimes, stops working for like 2-5 minutes and then starts working again. It might be some firewall related problem, but if so, what ports do Sql need to use tcp/ip connections? This might fix it but I don't think so, since it runs just fine on a Win2003 Server with the same firewall. On my local development machine (Vista) I get this problem.
Below is the complete error 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) "
Thanks beforehand for any and all replies!

I downloaded a project code for a project which was in the book ASP.Net instant results.
The code also came with a MDF file. I had sql server 2005 not Sql Server Express . So attached the mdf file to sql server succesfully. I could even see the tables and its data.
I could even get the website running. My web config file properly specifies the sql server and database. Here is the webconfig file line..
<add name="AppointmentBooking" connectionString="Data Source=DESKTOPDESKTOP;Initial Catalog=AppointDB;User ID=***;Password=********;Trusted_Connection = yes"
But when I try the register operation, I get following error. Any suggestions...???

I have SQL Server 2000, and a mix of workstations running XP Pro and 2000.I have several Excel reports that link via ODBC to SQL. My 2000 machines link up fine; however my XP machine 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 setting SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - could not open connection to SQL Server)" Again, I do not have SQL Server 2005, and I only get this message from XP Machines (with Firewalls DISABLED). Once we click OK on the error, it updates anyway. The ODBC driver for SQL Server is 2000.85.1117.00 on our XP machines. ANY ideas would be GREATLY APPRECIATED!TIA,Krista

The following exception is occured, when i try to connect the SQL server 2000 in remote machine.
System.Data.SqlClient.SqlException: 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 connection could be made because the target machine actively refused it.)
The Database server having the SQL SERVER 2000 & SQLSERVER 2005.
My connection string is (.Net 2.0 Web application)
"User Id=sa;Password=;Data Source=DBServerName,1433;Initial Catalog=DataBaseName;Network Library=DBMSSOCN;"
I have tried many ways but not working
1) Firewall Off
2) In connection string i have given the SQL instance name.
3) Change the (DB Server) machine name to IP.
4) I have give the TCP/IP port number followed by DBServerName (1433).
5) In SQL server 2005 - Changed the 'Surface Area Configuration' settings from Local Only to Remote
Still i'm getting the same exception.
Please suggest.,
Regards,
Nanda

I recently re-formated my personal server and installed SQL Server 2005 on it instead of 2000 which I previously used.
Now, I have imported the databases to the new SQL Server 2005, but I seem to get the following error when trying to access the database (from my asp.net page)
I've googled and searched the forum, without any luck. Now I was hoping for someone to answer this question, or perhaps guide me in the right direction.
Note: I've tried 5-6 different solutions that I found on the net, in vain.
Server Error in '/ph' Application.

Hello all,
I am running into an interesting scenario on my desktop. I'm running developer edition on Windows XP Professional (9.00.3042.00 SP2 Developer Edition). OS is autopatched via corporate policy and I saw some patches go in last week. This machine is also a hand-me-down so I don't have a clean install of the databases on the machine but I am local admin.
So, starting last week after a forced remote reboot (also a policy) I noticed a few of the databases didn't start back up. I chalked it up to the hard shutdown and went along my merry way. Friday however I know I shut my machine down nicely and this morning when I booted up, I was in the same state I was last Wenesday. 7 of the 18 databases on my machine came up with
FCB:pen: Operating system error 32(The process cannot access the file because it is being used by another process.) occurred while creating or opening file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf'. Diagnose and correct the operating system error, and retry the operation.
and it also logs
FCB:pen failed: Could not open file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf for file number 1. OS error: 32(The process cannot access the file because it is being used by another process.).
I've caught references to the auto close feature being a possible culprit, no dice as the databases in question are set to False. Recovery mode varies on the databases from Simple to Full. If I cycle the SQL Server service, whatever transient issue it was having with those files is gone.
As much as I'd love to disable the virus scanner, network security would not be amused. The data and log files appear to have the same permissions as unaffected database files. Nothing's set to read only or archive as I've caught on other forums as possible gremlins. I have sufficient disk space and the databases are set for unrestricted growth.
Any thoughts on what I could look at? If it was everything coming up in RECOVERY_PENDING it's make more sense to me than a hit or miss type of thing I'm experiencing now.
