I have a VB.net app that connects to a remote SQL server via TCP/IP. Most folks can connect just fine. However some enterprise users are in a corporate environment that will only allow connections through a corporate proxy server.
The VB app does the connect to the remote SQL server via a fully routeable IP address over port 1433, implemented via a series of table adapters.
Having no such experience, I have no idea what I need to do to my app to allow it to connect THROUGH a proxy. And what sort of interaction I will personally need to have (if any) with thier IT department to configure the proxy server in any way. The user mentioned that "Only permissible outbound connection is through proxy server and it is only allowed with TCP/IP port 80 and it is only possible by authenticating with Domain ID and password." I would assume that means the connection from the VB app to the Proxy server is over port 80 and that somehow the proxy server will know (or be told) to then route to IP address of the SQL Server over port 1433.
I realize that one possible solution would be to create a WebService that runs on the same machine as the remote SQL server and have the app connect to that. However that will require a lot of rework on the application. We are looking into doing that, but right now I need a short term fix that does not require such a major rework.
Can anyone offer any insight or links that might point me in the right
direction?
Thanks!

Hi,I created a small application to upload small video files on my
local machine and tested it to work perfectly on my local sql server
database. I then change the connection string to connect to the remote
database.When I do this and try to upload, the application hangs and
the video file is not uploaded. The file is small file only about 10MB
or less.When I upload the same file locally,it works perfectly fine and
uploads quickly without hanging.Here's a link to sample of my web.config filehttp://www.bleusolutions.com/sampleconfig.txt Here's a link to the pagehttp://www.bleusolutions.com/foto/uploadvideo.aspxI believe that this may be a database issue. I am running my
application locally
(http://localhost:4796/BleuS/foto/uploadvideo.aspx)and all I do is
change the web.config connection string to point to my local database
or to the remote database. When I point to my local database the application works fine as you can see: http://www.bleusolutions.com/images/localupload.jpgWhen
I run the application locally and change the connection string to point
to the remote database this is when I have problems with the same video
file. The application hangs for a minute or two and then it finally
finishes the upload. When I go to the database to view the table the
table takes a minute or two to open and then I get this message:http://www.bleusolutions.com/images/remoteupload.jpgAnd this is what the table looks like after I click Okhttp://www.bleusolutions.com/images/remoteupload2.jpg Any help on why this is happening or how I can fix this issue will be greatly appreciated. Thanks
I did not use Sql server for 2 weeks and now it shows the red small square on the server icon for SQL Server indication it is stopped. I can not now start it, it says access denies or not exist. Can you please help me to connect to it again as i do not want to re-install and los the databases. I have done nothing to it apart from i change my windows password as the system in the company you have to change it every 3 months, Do you think that might affects?
Please help!!!!!
I'm creating a SSIS solution where I use a WebService Task to get some data from an external Web Service.
I create a "HTTP Connection Manager" for the WebService Task. I enter the correct Server URL, and in the Proxy tab I enter the correct Proxy URL. The "Test Connection" button returns a success and everything works fine....
However, when I re-open my solution after having saved it, the "Test Connection" button returns a "Unable to connect to the remote server" message. the Server URL and the Proxy URL are correct but it seems that SSIS is not using the Proxy. If I create a new package with the same Server URL and Proxy URL it works fine.
Does anyone know anything about this problem? Is it a bug in SSIS or something that I'm doing wrong?

I have read all the posts regarding this error, but non-solve my problem as I had already addressed them.
I am setting up Merge Replication via the Web and I get this error when i try to sync. Let me give you some background.
I wrote a small windows test app to test merge replication, in which i am using RMO to accomplish the replication. This works. It syncs every time. I then copied the "sync" code from the winform application and created a Windows Service in which i placed "sync" code. The sync code did not change other than adding the additional following four lines:
_mergeAgent.InternetUrl = _internetURL;
_mergeAgent.InternetLogin = _internetLogin;
_mergeAgent.InternetPassword = _internetPassword;
_mergeAgent.InternetTimeout = _internetTimout;
where the internet url is https://ipaddress/virtualdirectory/replisapi.dll
I have been working with this for a while now trying to figure out why this works (on the same machine) in a winforms app but not through the web (via a windows service).
Any insight would be greatly appreciated.
Thanks...

Hi all,
I am having seriuos problems getting VoIP traffic into and out of my network via the ISA server which we just newly installed.
My network topology is such that the phones i am using for the VoIP service, sitting inside my network and behind the ISA server, have to register to some remote proxy server outside my network and as soon as it registers i can begin using the service. The VoIP service is on the platform of SIP and uses udp ports 5060 and 8080.
I have permitted the necessary ports on the ISA server for the service being UDP port 5060 and 8080 but still cannot get my VoIp traffic through the server.
Please i need some help here as regards something i am supposed to do or something i am not doing right on the ISA server to permit my traffic.
I am a newbie to this Microsoft ISA server and i hope you all understand
Thanks in anticipation to your replies.

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.

Any help appreciated

I'm getting "Access denied" error when I try to connect to SSIS from my desktop (Database Engine is fine). I'm a member of sysadmin within SQL, as well as an administrator on the server. I don't have any problem when I log on to the server directly via Remote Desktop and open SSIS.
I went into the surface area config tool, and I see that Database Engine and Analysis Services both expand and have a sub tabs to enable Services and Remote Connections, but Integration Services does not expand to a Remote Connections option, just Services. We're running MSDN Enterprise edition.
Does it matter if all the SQL services are using "Local System" for the logon ? I use an administrative logon on my SQL2000 boxes, and was fiddling with them on the 2005 box yesterday, but it seemed to cause more problems, so they are all Local System for now.
Am I missing something obvious ?
Hi. I'm (very) new to SQL Server. I have run into what seems to be a very common problem, judging by the number of Google hits, but it's not actually in the FAQs here, as far as I can see.
Situation
I installed SQL Server Express with Advanced Services 2005 on my Windows XP Pro laptop, using (with one exception) the default install. The exception was to put the data files on a separate partition (D: ) where I have more free space.
SQL Server Management Studio Express connects happily, and I set up a single data import table.
Issue: bcp Fails to connect to default local instance
I initially tried bcp in output mode, prior to working in earnest on importing my data. However the command line-
bcp MyDatabaseName.dbo.UserProfile out UserProfile.txt -T -c
Fails with the error-
Error = [Microsoft][SQL Native Client]Named Pipes Provider: Could not open a connection to SQL Server [2].
As I understand it, the local instance of SSE is the default, and should use a local (shared memory?) connection. This seems to work for Management Studion Express, but not bcp.
While investigating this problem, I tried enabling remote connections (all types) through the Surface Area Configuration wizard, and found that remote connections using either of:
bcp eSpacePh1.dbo.UserProfile out UserProfile.txt -T -c -S localhostsqlexpress
bcp eSpacePh1.dbo.UserProfile out UserProfile.txt -T -c -S mycomputernamesqlexpress
both work ok.
Extra Info
When starting Management Studio Express, it says something like "Configuring environment for the first time". However it says this every time it is started, not just the first run after installation, does this indicate some configuration data is not being successfully stored?
I have found threads that look similar to my issue-
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=836670&SiteID=1
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=3351349&SiteID=1
However these do not relate directly to bcp, and to be honest my knowledge of SSE is slender enough at this stage that i'm unsure if there are really relevant.
Any hints on how to proceed much appreciated.

Basically I've been using Visual Studio 2005 for a few weeks now moving a Pocket PC project from 2003 to 2005. When I hit the Start Debugging Button every time until today the project would rebuild and deploy to my pocket PC allowing me to debug etc but now I get
The remote connection to the device has been lost.
Please verify the device conection and restart debugging.
I used to get this problem in VS2003 sometimes and just like the numerous posts on different sites that I've looked at the problem eventually goes away and I'm none the wiser. One guy said that he found that if he went to bed the problem was resolved when he came back!
My PDA running Windows 2003 2nd Edition is directly connected to my PC via a USB port. I've rebooted my PC and done a soft reset on the PDA but it didn't help. I'm using ActiveSync 4.1.
Does anyone know how to resolve this problem?
Hello everyone, I am trying to connect to a remote SQL 2005 database from Microsoft SQL Server Management Studio.I enabled the remote connection on the server and creating a user on the server.I am trying to connect to the server from my workstation using sql server authentication with the login name already created on the server.
I am receiving this error: cannot connect to "server name"cannot open user default database. Login failed.Login failed for user "username".(Microsoft SQL Server, Error: 4064)
Can anyone help?
hello !
I am deploying a websete in visual studio2005 after deploying, when run a website Login Failed: The user is not associated with a trusted sqlserver connection. error occurs plese anybody helpme. urgent
Thanks.
I am attempting to connect to SQL 2005 server. The server and the VS 2005 are on the same computer. I have configured the db so it uses the security for asp. The log in section connects fine and checks for the user. I have combined the old db with the new ASP security. If the user is not found then I open a connection using the open command and check for the user in the old part of the db. The is where I have trouble. I get the message below that the server connect but then won't allow remote connections. I have check the setting and the allow remote connections is checked. Thank in advance if anyone can help.

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: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)
I am now trying to connect with the correct details to an MS SQL machine.
The machine in question is not local to me and the internal ID is //bobsmachine01.
I know this is a dumb question, but I shall ask it anyway...I am using MS Access 2000's "Upsizing wizard" and it asks me for the machines name - what should I put to connect to it??
I know the IP of the machine and the internal ID for the MS SQL Server.
Any help much appreciated,

How would I connect to remote SQL 2005 database using Management Studio?
The only difference from local DB is that I type IP address instead of server name, right?
I'm getting error:
Testing the registered server failed. Verify the server name, login cridentials, and then click Test again.
Additional information:
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)(Microsoft SQL Server, Error: 53)
I did everything from article "How to configure SQL Server 2005 to allow remote connections"(http://support.microsoft.com/?kbid=914277&SD=tech). SQL Browser enabled. Both TCP/IP and Named Pipes are enabled. Exceptions in firewall for sqlsrvr.exe and sqlbrowser.exe added.
Did not help.
What else could I check?

Could someone tell me how to remote connect to other server. Everytime when I try to connect to other server, I get an error message. Eventhough I have opened the 1433 port, allow the remote connection using both TCP/IP and named pipes, and open the firewall for connection. The following is the error message
"An error has occurred while establishing a connection to the server. When connection to SQL Server 2005, this failure may be caused by the fact that under the default setting SQL Server does not allow remote connections.

View 1 Replies View RelatedI have researched over and over on how to solve the error code below. I have tried every suggestion under the moon and still get the same error. Please provide some insight. Here is exactly what I have done regarding the remote connection issue:
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)
History:
1. Created a test site on my local machine (using MS Visual Web Developer 2005 Express Edition) call WebSite8 for test purposes.
2. Simply created a single page to allow users to create an account by dragging and dropping the CreateUserWizard onto the designer screen.
3. Performed some basic formatting (font, theme, etc) on the web control.
4. Ensure that TCP/IP and allow remote connection defaults were changed to allow remote connections.
5. Verfied that the login control worked on my local machine. Everything worked fine. I was able to create two new users and was sent to the "complete" portion of the control.
6. Opened the aspnet_memberships and aspnet_users databases to ensure that the two test accounts were created.....everything good so far.
7. Copied all files from WebSite8 (1. App_Data Folder - includes ASPNETDB.MDF file created by Developer when I dragged and dropped the CreateUserWizard onto the designed sreen, 2. the main asp web page I called createaccount.aspx, and 3. web,config file) via ftp to my test web site hosted by 1and1. My test web site is named something different that WebSite8.
8. I created a test.htm page on the 1and1 web site to link to the createaccount.aspx page which is in the same path as the test.htm.
9. The process let me enter the user name, password, etc but when I hit submit, I get the error listed below.
10. Followed some other research suggestions and verified that ApplicationName in the aspnet_Membership was set to "/". It is.
11. I checked the web.config file and it does not seem that any connection strings were created when I dragged the CreateUserWizard onto the screen. Not sure if this is an error on this control or not or if it is ok as is(?)
I believe there is some sort of issue on the hosted web site where the sql server is not linking to the database on the hosted site and is likely trying to link back to my "local" server......just a feeling.
I have tried everything that I can think of after performing relentless research on this error. I am new to database programming, ASPNET 2.0, SQL, etc but I catch onto things very quickly.
Hi,
I've worked with SQL Server plenty but never in this specific manner. Hoping someone can shed some light.I have a webform on web server A that needs to talk to a SQL server database that web server B accesses via its web application. I do not haveany privelidged access to server B or the sql server it uses (no FTP to webserver, no remote access via Enterprise Manager to the SQL server). The Admin of Server B told me that I can use a DSN connection to talk to the SQL server database that the web app on server B uses. He emailed me the names of the SQL database tables AND a copy of the web.config from server B which shows the DSN implemented like this:<appSettings> <add key="dsn" value="data source=sql3.domainname.net;database=dbname;User Id=dbuserid;password=dbpw;" /> <add key="default_language" value="en" /> <add key="error_email_to" value="someone@domainname.com" /> <add key="baseHref" value="http://www.mysite.com/" /> <add key="website_name" value="$$$$$$$$$$$$$$$$$" /></appSettings>
I was planning to run my webforms on Server A where I do have FTP, Control Panel, etc.So, I wrote this code into my VB.NET codebehind file.
Dim oODBCConnection As OdbcConnectionDim sConnString As String = _"Driver={SQL Server};" & _"Server=sql3.domainname.net;" & _"Database=dbname;" & _"Uid=dbuserid;" & _"Pwd=dbpw"oODBCConnection = New Odbc.OdbcConnection(sConnString)oODBCConnection.Open()... commands to access data and load something into a control on a webformoODBCConnection.Close()
When I attempt to run the webform in my browser from Server A. I'm getting this error:ERROR [08001] [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. ERROR [01000] [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).The error is EXACTLY the same whether I place the appSettings section in server A's web.config or leave them out.I have obvious questions about the error like...Might sql3.domainname.net simply be refusing communication requests that don't come from the Server B domain?Might the sql3.domainname.net be setup so that I need to use another protocol (not tcp/ip)?Might my code need to be changed to support this type of connection (i.e. I didn't code it right)?I spent some time reading http://support.microsoft.com/kb/328306/en-us but I'm at a loss as to what the best course is to take for debugging this.Thanks in advance for any insight you can offer.

I had made an application which is using SQL Expresss.When I deploy that application on a server where only .Net Framework 2.0 is installed then it gives an error of remote connection.Does that need some prerequisite for SqlExpress or the reason of error is something else.
