Error: Unable To Connect To Server 'servername'
Apr 29, 2008
Hi,
I am trying to connect to SQL Server through Query Analyzer but getting following error: (SQL Server is at remote web server where i have my website hosted.)
Unable to connect to server [server IP]:
Server: Msg 6, Level 16, State 1
[Microsoft][ODBC SQL Server Driver][dbnetlib] Specified SQL server not found.
I have searched this forum for this error and performed following workaround as suggested in some threads-
1. checked and set "TcpPort" registry setting.
2. TCP/IP is enabled in Network Utility.
3. "start SQL server if it is stoped" checkbox is unchecked while connecting.
But, I am still getting the above error. Should i re-installed SQL Server 2000? Any help?
Thanks,

I thought I would post how I got remote t-sql debugging working in my environment. Hope it might help someone.
I have two domains, DomainA and DomainB. DomainB has a one way external trust to DomainA. Dev Vista machine running VS 2005 is in DomainA logged in as user DomainAauser. SQL 2005 running on test Windows Server 2003 DC machine in DomainB under user DomainBuser. When trying to 'step into stored procedure' in VS, whether my data connection used windows authentication or sql server authentication, I would get the 'Unable to start T-SQL degbuggin...'. I could debug t-sql when I logged into the domain controller (console or rdp) and running VS on the server. I changed the SQL Server service to run under the DomainAauser account and I can now remote t-sql debug using both window authentication and sql server authentication. Hope this may help anyone that might run into this.
Regards,
RMcc

I have loaded NT4 onto a machine with 256MB's of ram. I have put on SP6 and the hard drive is 80GB's in size. I then loaded in SQL Server 6.5 and set up my default database at 250MB's in size. I can ping all other computers on the network and they can ping me but when I try to register the database it give me a unable to connect error. This is the 10004 error. The error is Execomm and it says the DBPROCESS is dead. I guess thats cause it won't connect. The Sqlserver is running and so is the sqlexecutive running.
Help, Help, Help.
TIA

I am getting the following error:
Unable to connect to server. Reason: 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)
Also, I am running the Upgrade advisor from my machine (SQL 2000) and trying to access the SQL 2000 db on another machine. So I do not have SQL 2005 in any machine.
Can anyone tell me whts wrong.
Pls Advice!!
Thanks

I've installed SQL2005 on a server already running SQL2K on my laptop. SQL2K is the default instance, so I'm trying to connect to SQL2005 using MYSERVERSQL2005 as the instance.
The steps that I've taken are to apply SP2 and enable remote connections (TCP & Named pipes). I've also made sure the SQL Server Browser service is running and enabled.
The error message that I get via SQL2005 client tools is "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) (Microsoft SQL Server, Error: -1)"
I dont understand as to why i am unable to connect to 2005.
Any ideas?

SQL Express running on Server 2003 SP1, not a domain controller - but prior to installing SQL Express, I did dcpromo promote and then demoted it back to a workgroup server.
Connecting with Vista build 5600, Studio express 9.00.2047 with MDAC 6.00.5600.1638. Server 2003 MDAC is 2.82.1830.
I came across this article on the net:
http://www.developersdex.com/sql/message.asp?p=1867&ID=%3C309C7496-F36B-4398-9C52-322E6CB8DE3B%40microsoft.com%3E
Is my mis-matched versions of MDAC causing me this grief?
Otherwise, I have remote set up for TCP and Named Pipes, I've run sp_configure 'remote admin connections', 1; my login is set to SQL Authentication with everything granted. I've tried running the service as network, local and MachineAdministrator; ports are open per:
http://support.microsoft.com/kb/555585
I wanted to ask before I start replacing the MDAC on either the Vista or Server 2003 machine... If that's the problem, which version(s) do I change? to?
Full error message:
An error has occurred while establishing a connection to the server. While connecting to SQL Server 2005, this failure may be cuased by the fact that under the default settings SQL Server does not allow remote connecitons, (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 1326)

My system config is VISTA Ultimate, Visual Studio 2005 SP1, SQL SEVER 2005 SP2. Using 2005 SQL Server Management Studio I am unable to create a servername/aspnet login account.
I right click logins and get the new login form; key ASPNET Login Name; select Windows Authentication; click search; I get the Select User or Group form; under object type I select all three; location I select my server name; if I enter SERVERNAME/ASPNET and click Check Names I get an error; if I click Advanced and Find Now; ASPNET is not listed in Name(RDN) list.
I tried aspnet_sql.exe -E -A all; that did not work.
Where can I find information on creating an ASPNET Login after experiencing the above problems?

I'm using SQL Manager from my Enterprise server to connect to my SQL Express server that will act as a witness to a db mirroring system. If I try to connect to the SQL Express server using its IP address, I get a "named pipes error 53." If I connect by browsing the network and connect to the Name of the Server "MachinenameSQLExpress", I am successful. I would like to be able to connect to the IP directly as it's not dependant upon certain services to be started or configured a certain way.
Thank you,
Chad

Hi to everyone!
Here is my problem: I have SQLEXPRESS running with Windows Authentication on a "server" PC named "ASUS1", and I need to connect from a "client" PC named "Presario1", user "Mauro", connected through a peer network (I use a cross-over cable); both PCs belongs to the same workgroup named "RMT-WORK", and they can see each others shared folders without problems.
I have installed the connectivity components + Management Studio Express on Presario1, and enabled named pipes and TCP/IP protocols; then I've got SQL Browser running. I have also added the Login "Guest" on ASUS1SQLEXPRESS.
When I start Management Studio Express on Presario1 and browse for servers I can select "ASUS1" as database engine but when I try to connect I receive "Error 40: could not open a connection to SQL Server" (same result using SQLCMD); I have tried to add on ASUS1SQLEXPRESS a user "Presario1Mauro" with "CREATE LOGIN [Presario1Mauro] FROM WINDOWS" but I receive a "Windows user not found" error...
Can anyone help me?

I just installed a SQL Server 2005 Express SP2 instance on a server with an existing SQL Server 2000 SP3 installation. (I need SQL Server 2005's INSERT from an EXEC capability). It's working great now except for one thing: I can't link any other SQL servers! I've already successfully added and queried a linked Oracle server, but attempting to add a linked SQL server gives me the following error, no matter which SQL provider I try to use:
Code Snippet
"The linked server has been created but failed a connection test. Do you want to keep the linked server?"
Additional information:
--> An exception occured while executing a Transact-SQL statement or batch (Microsoft.SqlServer.Express.ConnectionInfo)
--> Cannot create an instance of OLE DB provider "SQLNCLI" for linked server "SERVERNAME". (Microsoft SQL Server, Error: 7302)
The technical details reveal the error source as "sp_testlinkedserver".
I've scoured the net and premier support for advice on this problem, but the little I found wasn't helpful. I've tried reinstalling the SQL Native Client, but it didn't help. I've tried uninstalling SQL Server 2005 Express completely (including management studio and native client), rebooting, and reinstalling everything, with no luck. The server (obviously) does not have a firewall enabled. I've tried stopping the SQL 2000 Server installed on the system, no help. If I create a test .UDL file on the system, pointing to any of the SQL servers I'm trying to link, clicking the "Test Connection" button returns successful. I'm also able to connect to and query the servers directly from the SQL 2005 Express Management Studio. I just can't add them as linked servers.
The server is running Windows 2003 SP1, SQL Server 2000 SP3, and SQL Server 2005 Express SP2 (the default "SQLExpress" named instance). I've tried setting up SQL 2005 Express to run under the network service account and under a domain account used by the other SQL 2000 servers.
From other SQL 2000 servers, I can connect and link to the SQL Server 2005 Express instance successfully. I can also successfully add linked SQL servers in SQL Server 2000 instance installed on the same server. Only adding linked SQL servers in 2005 Express seems to be broken.
Anyone have any other suggestions? I'm totally baffled. Thank you so much for any helpful advice.

I upgraded my 6.5 server to 7.0 two days ago running into small problems with the database upgrade wizard. I had some small problems with security which took me some time but was not that difficult once I figured it out. I then proceeded to switch back to 6.5 mode to transfer all the data that had been done that day to my development machine so I could then import it to the SQL 7.0 version. When I was done with the transfer I switched back successfully, started the server successfully, but I was unable to connect. I get the error "Connection could not be established...", so after several attempts to connect and shuting the server down I now am at a loss. The server runs fine in 6.5 mode but it will not connect in 7.0?? Tonight I am going to try to reinstall SP1, if that does not work I am going to try to reinstall SQL 7.0. Any suggestions???

On a fresh installation of SQL Server 6.5, I have
opened the EM and registered the server but am unable
to connect. I get the error of 'A connection could not
be established to [ServerName]- [DB-Library] Unable
to connect: SQL Server is unavailable or does not exist.
General Network Error. Check your documentation.'
I've tried connecting with all different DB-Lib settings
to no avail. Ultimately, I want to use TCP/IP. I am,
however, able to connect to other SQL Server boxes from
this EM, just not the local server. I am able to stop
and start the services from Control Panel and from SQL
Service Manager.
Since I haven't been able to log into the local SQL Server,
I've registered the server in EM to log in with sa and a
blank password. I've already completely uninstalled SQL
and reinstalled it to see if that would help. It didn't.
Does anyone have any idea what the problem could be?
Thank you!

Hi,
I am running SQL 2000 on Windows 2000 Server. The clients are running different OS ranging from Win 98/NT/2000. Although i am able to connect to the local host, but whenever i try to connect over the network the following error pops up :
unable to connect to server <server name>
Server : Msg 11, Level 16, State 1
[Microsoft][ODBC SQL Server Driver][TCP/IP Socket]General network error. Check your network documentation.
I checked up the event long on the server and found the following entry:
Event Type: Warning
Event Source: MSSQL$NETSDK
Event Category: (8)
Event ID: 19011
Date: 1/20/2003
Time: 2:12:32 PM
User: N/A
Computer: <computer name>
Description:
The description for Event ID ( 19011 ) in Source ( MSSQL$NETSDK ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event:
(SpnRegister) : Error 1355.
May i further clarify that this error started today n till last week end (saturday, i am
stationed in India) there was no problem and the users were able to connect to the server
without any problem. My network engineer feels that its an sql problem and has nothing to do with network related issues.
i would appreciate if anybody could help me out. thanking in advance

I am unable to connect to SQL Server using isql_w or enterprise manager. The ODBC settings register successfull and the services show as started. I have tried starting SQL server in single-user mode with minimum config to see if memory is a problem but still cannot connect. The error logs show SQL as having started successfully with no errors. Has anyone got any ideas?

From my Win98SE box with MDAC 2.6sp1, I can't connect to SQL (win2k, sql2k).
I've tried everything I know but nothing works.
I always get the following error:
Unable to connect to server 192.168.1.2
ODBC: Msg 0, Level 16, State 1
[Microsoft][ODBC Sql Server Driver] Timeout Expired
some additional info...
- both computers are in a workgroup, not in a domain.
- this is a home network and they're connected via a Linksys cable modem router
- another box on this same lan can connect to sql just fine, although it's
running win2k.
- all boxes have identical DSN, Subnet...settings
- I also installed Jet4.0sp1 just in case, but that didn't help either
- I'm primarily trying to connect via TCP, although I have tried Named Pipes
as well
- i can ping both boxes from each other just fine
- odbc ping fails
MDAC has worked beautifully for me for the last several years. Did MS
change something recently...or is there another problem?
Thanks, Andre

Hello. I am very new to SQL Server. I've tried to look through other posts on the forum but did not find the solution I needed. Please help.
I have SQL Server running on Machine1 which I am able to connect to. What I want to do is connect to this server through a Machine2 that is on my network.
Both Machines run on WindowXP Professional
On the server of Machine1, I have:
1. Under the security tab, I have created a New Login using SQL Server Authentication (general tab), checked all server roles (server roles tab) and checked to permit all databases (in the database access tab)
2. On the server, went to properties -> security tab and allowed for SQL Server and Windows authentication
On Machine2 when I try to register the server of Machine1 through the Register SQL Server Wizard, I am able to see the server. However, when I use the newly created Login Name and password (from step 1 of above). I get a Login Failed for user message. When I try to connect to the server through Query Analyzer I also get an unable to connect to server message (Server: Msg 18456, Level 16, State1)
What else do I need to configure to make it work?
Thank you!

If you place an image of your server on a rebuilt server, rename it andchange the SID. You get an error message “UNABLE TO CONNECT” when youuse the SQL Query analyzer on a desktop computer to connect to theserver (hosting the image). If you add the server (hosting the image)to the Windows2000 server domain/active server and restart the server(hosting the image), you get the following error message: "YOUR SQLSERVER INSTALLATION IS EITHER CORRUPT OR HAS BEEN TAMPERED WITH (UNKNOWNPACKAGE ID). PLEASE RERUN SETUP."Wouldn't you think changing the name, the sid and adding it to a domainwould be enough to access it. I even created a new ODBC connection.*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
