Remote Connecting To MSSQL Through A VSTO Addin
Jan 28, 2008
Hi there everybody
I am a novice in using MSSQL and Windows 2003 solutions so I am having some problems.
I have made an excel addon in VSTO that connects to a MSSQL2005 server running on Windows 2003 on our internal domain, and it works great. Connection when I specify the domain adress is flawless. The thought is though that the addin is supposed to been used also outside our domain, so I have opened up our router and redirects all traffic to and from port 1433 to our MSSQL-server. This part should be ok.
I can then not connect to this server with our external ip specified. The error message Visual Studio produces is "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: TCP Provider, error: 0 -A connection attempt failed because the connected party did not properly respond after a period of time, or established connecteion failed because connected host has failed to respond.)"
I have read around and tried to fix this myself. I've specified to accept "Locale and remote connections" in the Surface Area Configuration Tool that shipped with MSSQL on both TCP/IP and named pipes. In the SQL Server Configuration Manager is the protocols Shared Memory and TCP/IP enabled. I have enabled all the IP-adresses under TCP/IP and specified 1433 as the port to use for all of them.
As for possible other problems I can see:
I have read a couple of places that people have tried to connect with the MSSQL server through telnet when specifying the port 1433 (telnet mydomain.net 1433). I have tried this but telnet is not getting a connection. Dont I have to open/forward more ports on the router to get telnet through?
I cant ping our external ip. Isnt this also a problem that is related to that I have not opened/forwarded ports on the router to our MSSQL server?
Do anyone of you have any tips or steps to take to narrow the problem down? This is not the forum for VSTO but thats not really where the problem is either, I think. It is probably somewhere in the configuration of MSSQL or Windows 2003. The server machine is set up as domain controller and DNS server for our local net.
I will appreciate all input, I am stuck at the moment...

Regardless of which one is installed first, what's the best wayafter that to move or copy database objects like tables, queries,reports, etc. from the XP/developer box to an SS 2005 Server??Thank you, Tom

This is kind of the wrong place to ask VBA questions, but I've been poking around for a day and haven't got the answer, so I am hoping I can get some help here.
I am wondering if I can connect to MSSQL in MS Word Macro. If so, can I have some sample code please?
Thanks

I'm just starting to learn ASP.NET (3.5) and I've gotten most of it down, but my failure to use a database is realy crippling my learning ability.
How do I connect to MSSQL? I have Godaddy so they provide me with the username, password, url, etc. If I could get a few examples for the following it would really help ALOT!

This is the first asp.net application that I am trying to make.
After hours struggling wiht Plesk 8.1 I managed to create a MS SQL database and add a table to it.
How can I make a connection to this database now through ASP.NET?
Just mention it that I am using Visual Studio.net and I am working on a remote server.

Hi all,
I'm running a MSSQL DB on our web server and currently I need to use Teratrax Database Manager to connect and manage it. Unfortunately this doesn't seem to have any features to export the data from the database.
I read somewhere about an online MSSQL tool which can manage online databases? Does this exist?
What tool would I use to connect to my database to export data from it? I have an evaluation copy of MS SQL Server 2005 but my knowledge with it is limited and I'm having trouble getting it connected to a remote DB (local DBs are fine).
Any help would be appreciated!
Thanks!

Hello,
Hope anyone in here can help.
I have tried to install the SQL Server 5 Express, but can't seem to get it to work properly.
I got a terrible name set as default for my database, as well as a terrible name for my username.
I can't find a place to change this to something more manageable.
It is further set to windows auth, but trying to set it to both, and trying a username (and password) always gives me a log in error.
I've tried searching all over the net and in here for a simple tutorial, but can't seem to find one that helps me more than it confuses me.
*****
The second part of the problem is that I have a java program which I want to connect to the database and use the tables in it, but I am at loss to how I can find what username (and password) I am supposed to have, what "url" it needs etc.
I have the jdbc driver so that part should work, I can successfully log to other mssql databases (at work/school), but not my own.
Hope you can help, and thanks in advance.

Hello,
I am developing an application which needs JDBC connection to a Named Instance of SQL Server 2000 (other than default instance). I am facing problem in this regard as my code gives an exception "Time Out" or "Connection Failed". However it works fine with the default named instance...The main driver class is "com.microsoft.sqlserver.jdbc.SQLServerDriver"
and Connection URL is
"jdbc: sqlserver://localhost;instanceName=Testing:1432;databaseName=testDB;"
It gives the exception that Unable to connect to named instance....
Please if any one have any knowledge in this regard....do let me know....I have read an article on MSDN according to which on MS SQL Server 2000 the named Instance other than default can be accessed only through named pipes.
http://msdn2.microsoft.com/en-us/library/aa224779(sql.80).aspx
if some body can tell me Connection string for JDBC driver which utilizes named pipes...the it will be very help full for me.........any help from MSDN Experts is really appreciated...
Thanks

I created a linked server to a DB2 database and I can pull data fine, but when I try to insert/update/delete it tells me "SQL0471N Invocation of routine "SYSIBM.SQLTABLES" failed due to reason "00E7900C"" when trying: DELETE FROM DB2LinkedServer..SPACENAME.TABLENAME
I believe I need to send a clear string to DB2 that doesn't get compiled on the sql server side. Is there something like openquery that I can use for DML statements in SQL Server?

Hey, all. I've mainly worked with MySQL databases before. I'm working on an (old) ASP page that uses this connection string:strConnect = "Provider=SQLOLEDB; Data Source=SQL1.MYDBSERVER.NET; Initial Catalog=...; User ID=...; Password=..."
It works fine on the production server, but the local copy fails if I try to access the Products page (which uses the database), with this error: Microsoft OLE DB Provider for SQL Server (0x80004005)[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied./html/products.asp, line 19Similarly, if I plug the connection info into Tools/Connect to Database in Visual Studio, I get: Connection failed:SQLState: '08001'
SQL Server Error: 17
[DBNETLIB][ConnectionOpen(Connect()).]SQL Server does not exist or access denied. Am I doing something wrong? Do I need more info from the hosting provider to connect remotely? Or is the database not accepting remote connections at all?Thanks in advance for your help!

I am using SQL Server 2000 database in my VB.Net project.
My VB.net application is installed one two machines in different cities i.e. there are two separate databases.
First machine's IP address is say 202.33.44.55 and other machine IP address is say 203.33.55.66. Now I want to use each others databases i.e. I want to set their database group.
So that in my VB.Net's application which is installed on 202.33.44.55 I could see data of the 203.33.55.66 by just changing the connection string

Hi to all:
I always had a problem connecting to SQL Server from home using EM.
I do add a new server registration, but i always get the following exception:
A Connection could not be established to IP ADDRESS
Reason: SQL Server does not exist or access denied.
ConnectionOpen(Connect())
At the same time, I do use a utility, found at http://sql.bhaidar.net to connect to the same database and works perfect.
Is there any configuration I should do to my pc, don't know maybe some port configuration or so, to allow EM to connect to those remote databases?
Thanks in advance.
Regards

Hi
I've got a desktop and a notebook and both are connected to the router. On both I've got Sql Server Express and Sql Server Management Studio Express installed. I need to connect to a remote Sql Server (using user ID and password) which works fine on my desktop, but fails on my notebook: Error:0 and Error: 10060.
I checked all router settings and notebook settings, but I don't know what I am doing wrong. I got myself another notebook and installed Sql Server Express plus Management Studio, which did not work either.
Hopefully someone can help.
Thank you.

I have recently taken over as webmaster at my company and need help connecting to our remotely hosted SQL server. The company who is hosting it will charge me "support time" to explain how to connect to it.
The database is used to store data and application information for our customer service center. So it is ALL database driven...
i have installed SQL Server Enterprise Manager on my machine, but have no ideas on where to even being trying to connect. I have the name of the server, password....etc. But do not know where to configure a connection.
ALSO, when i install my Enterprise Manager the first options askes me whether i want to create a new instance of SQL server on a local or remote machine....i am guessing my local machine right...??
any insight or direction is greatly appreciated.

Please bare with me as I do not have much knowledge in this area with MSSQL.
I have installed MSSQL 2000 Developer and I have setup a database which I am able to connect to and work fine with from the actual server MSSQL is installed on.
The problem comes in when i try to connect to that same database from a different remote server. It will not connect to the DB from this remote server but I know all the connection information is correct so its something on the MSSQL DB server causing this and not on this remote server.
Someone I know has had this problem and has fixed it but they wont tell me how. All I know is they said something about manually opening the ports on the MSSQL server and he also said when you set it to dynamicly determine the port that MSSQL is listening on it errored out. however if you set it staticly to 1433 it worked fine.
Ive also installed SP4 in attempt to fix this but no luck with that either. And I can also get the same exact remote server to connect to completely different DB server without issues.
If anyone can please help walk me through this I would be greatly appreciate and I am also willing to pay some money if it will make my life easier.

Hello
I wrote a web app (vb.net) with mssql 2005 express edition DB.
I created a vs2005 setup project and added it to my app solution.
On my local computer it works fine (using IIS 5.1).
Now, I'm trying to deploy the app on a remote server (with mssql 2005 express edition installed) but when I try to run my app via the remote server's IIS, I get this Error message:
ERROR: Could not connect to database.
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).
My app connectionstring looks like that:
<connectionStrings>
<add name="SiteSqlServer" connectionString="Data Source=localhost;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=False"
providerName="System.Data.SqlClient" />

</connectionStrings>
<appSettings>
<add key="SiteSqlServer" value="Data Source=localhost;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=False"></add>
Can anybody tell me what I'm doing wrong and how to fix it
