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.
In my SQL Server Management Studio Express (SSMSE)=>Object Explorer=>Databases, the "NORTHWND" database was screwed up and is deleted completely. But under the same Object Explorer =>Databases, there is a database "C:SSMSE-BookChapter12WINCH12NORTHWND.MDF". I need to use this "NORTHWND" database in the SqlConnection. How can I specify the "Initial Catalog" (or "database") in the New SqlConnection code statement (in the ADO.NET 2.0-VB 2005 Express programming)? Should it be like the following:
Dim sqlConnection As SqlConnection = New SqlConnction("Data Source=.SQLEXPRESS; Initial Catalog=C:SSMSE-BookChapter12WINCH12NORTHWND; Integrated Security=SSPI;") ? Or what is the right code statement for connecting to it?

I have SQL server express 2005 installed on my pc as instance SQLEXPRESS.
I have created a Visual Basic applicaion with the following as connection to the SQL server express 2005 running on the same PC: **************************************************************************************************** Dim lconnectionString As String Dim builder As New SqlConnectionStringBuilder Dim cmd As New SqlCommand Dim reader As SqlDataReader Dim parameter As SqlParameter builder("Data Source") = ".SQLEXPRESS" builder("Initial Catalog") = "" builder("AttachDbFilename") = "C:My DocumentsVisual Studio 2005Projectsabcabcabc.mdf" builder("Integrated Security") = True builder("User Instance") = True lconnectionString = builder.ConnectionString Dim sqlConnection1 As New SqlConnection(lconnectionString) cmd.CommandText = "SP_add_collection" cmd.CommandType = CommandType.StoredProcedure cmd.Connection = sqlConnection1 sqlConnection1.Open() *******************************************************************************************************************
It seems that i can not connect to the abc.mdf in SSMSE while the VB program is running. (ERROR: Database 'C:My DocumentsVisual Studio 2005Projectsabcabcabc.mdf' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details. (.Net SqlClient Data Provider) )
If i connect to the abc.mdf first in SSMSE, then run the VB program afterwards, it gives me the error on this line -- sqlConnection1.Open()
I want to be able to access the abc.mdf database with both SSMSE and VB at the same time. Could anyone help me on this ?
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.

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.
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.
Hey guys, I am new to the SQL server scene and I am having some trouble connecting to a remote SQL Server with SQL Server Management Studio Express. I have the username, password, IP address, and port necessary to log in but am apparently not plugging them into the correct places. Can anyone at all point me in the right direction or somewhere that I might at least find the answer? I appreciate any help that can be provided.
In order to fix a web application bug the developer told me to to edit a stored procedure on my hosted SQL 2005 server. The hosting company's support say I should be able to do this using SQL Server Management Studio Express. I installed SSMSE, but it seems to want to only want to connect to a local server. Can I use this utility for remote DB management, or is there something else I need instead?
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. 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 tried working out solutions from various websites. But the no solution is effective. Could anyone help me in solving this issue.
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.
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:
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, Sorry if this is the wrong forum. I'm trying to connect to a remote server (on shared hosting) with Management Studio Express. I tried using it on Vista and it connects to the server and database perfectly. However, on Vista it gives the following error everytime: TITLE: Connect to Server------------------------------ Cannot connect to sgc.gbdns.net. ------------------------------ADDITIONAL INFORMATION: An error has occurred while establishing a connection to the server.

I have installed SQL server 2005 express on my main server.
It has been installed with windows authentication.
I can use sqlcmd -S machinenameinstancename to connect to the server, but when I try to connect from another machine on my lan, I get the error about user not part of trusted sql connection msg 18452 level 14 state 1
I have tried using a windows username and password from my server to access it but that fails also.
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
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.
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:

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.
I have a software to connect the SQL Server as DB, and it is ok to connect to the SQL Server 2000 on the remote server in our firm, but got errors when doing the connection to the SQL Server 2005. the error messages are: Error #1: ADO Error #-2147467259 Description SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF].

I'm using SQL Server 2005 version 9.00.1399.00, not the Express version. Should I update the SQL Server 2005 Network Configuration in SQL Server Configuation Manager? But I don't know what should be set to "Enable" or Disabled". Is any other place need be configured?
I have a local SQL Server 2005 instance running, and I would like to have another user on my network connect to this instance. However, when he tries to connect, he always receives the same error message:
"An error has occured 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 28: - Server doesnt' support requested protocol)"
So, I checked the properties for the server, and under the connections tab the allow remote connection box is checked.
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'm having a big problem with a SQL 2K5 cluster (using standard edition). I can get onto the box and connect to the sql server locally fine. However when I try to connect remotely I get errors.
Let's call the two sides of the cluster, CL1 and CL2 and the "virtual server" is CL3. Locally I can connect without any problem at all to the SQL server, but I just can't connect to it from any remote machine.
The server in question is instance name LMS_PRD running on CL3, port 10051. TCP/IP is definitely enabled for local and remote connections (I have checked this in the SQL server surface area configuration). I can connect locally without any problem. Also, locally, if I do,
telnet CL3 10051
it connects fine
From a SQL 2000 box - when I try to connect from sql query analyzer, I get
"Unable to connect to server LMS_PRD Server Msg 17 ... SQL server does not exist or access denied"
Client network utility shows server alias - LMS_PRD, TCP/IP, CL3LMS_PRD,10051
[I can connect to other SQL 2005 servers OK from this same server using this same method]
On this box, when I do telnet CL3 10051 , I get "Connecting to CL3...Could not open a connection to host on port 10051 : Connect failed"
[When I do a similar one for another SQL 2005 box, "telnet U01 10051", it connects fine]
From another SQL 2005 box - when I try to register the server, I get
"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 thew target machine actively refused it.) (Microsoft SQL Server, Error: 10061)"
IN the SQL native client configuration it shows alias name - CL3LMS_PRD, server=CL3LMS_PRD, protocol tcp, parameters 10051
Again if I do telnet CL3 10051, I get the error above.
From this same box I can register another SQL 2005 server without any problem and do the telnet to it OK
Just to emphasise:
(a) The SQL server configuration manager shows that TCP/IP is enabled, and that 10051 is the port (in IPALL, TCP port). Also I have checked the SQL server errorlog - it is definitely using 10051 as the port.
(b) The SQL server surface area configuration shows under local and remote connections using both TCP/IP and named pipes selected (I've tried both this and the using tcp/ip only option)
