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

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,

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?

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)

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?

Hello everybody
I wrote a vb.net win app that uses a mssql 2005 express DB.
On my localcomputer everything worked without a problem.
Now I wish to deploy my app on a remote computer (that has mssql 2005 express installed), so. I added an app setup project to my project using the vs2005 setup tool, installed the app on the remote computer, and copied the mdf file to the remote computer.
I'm able to see the DB through the remote computer mssql manager, But when I try to start the app on the remote computer I get this error massage :
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. error: 0 - No process is on the other end of the pipe.)
my connectionstring (in the config file) looks like that :
<connectionStrings> <add name="Info_Manager.My.MySettings.MaxinetConnectionString" connectionString="Data Source=DOTAN-XPSQLEXPRESS;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" /> <add name="Info_Manager.My.MySettings.MaxinetConnectionString1" connectionString="Data Source=DOTAN-XPSQLEXPRESS;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" /> </connectionStrings>
by the way changing the user instance attribute to "false" didn't help.
Does anybody know how to fix this problem.

Every time i reboot my NT Server and the SQL server service starts up. It logs this message to the event Viewer
Severity: 9 Error:10004, OS: 11001 Unable to connect: SQL Server is unavailable or does not exist. General network error. Check your documentation.ConnectionOpen (gethostbyname()()).
I don`t have any problem with the databases, all the users are able to connect to server and database without any problems, looks like everything is working at its best. But i am little concerned about this error message.
Please help
Thanks

Everything has been working fine our SQL Server (lets call it Server A) (v2000 under NT 4), however sometime over the weekend it is unable to connect to one of our other SQL Servers (Server B).
In the Event Viewer I found this error:
SuperSocket info: Failed to get Exclusive port use(MSAFD Tcpip (TCP/IP)): Error 10013.
Everything on this server appears to be working fine, as in everything can connect to Sever A that needs to, but Server B can't connect to A, nor is it working the other way.
Also, Server A SQL Services run on port 2006, and B is on the standard 1433. Everything has been working with this up until today?
Any ideas?
Thanks!

Let me start by saying that, yes we know v6.5 is no longer supported byMicrosoft and that moving to SQL2000 might resolve our problem.Actually the migration to SQL2000 is 1 to 2 months out and in the QAphase now. Unfortunately we need to resolve the current 6.5 issue nowas it heavily impacts a major revenue stream for the company with everyoutage we encounter.The Problem:At least once every 24 hours the SQL Server begins disallowing new userconnections. When this happens the 2 CPUs begin to thrash. About 5minutes later the error log begins to print out the following errormessage: "Unable to connect. The maximum number of '500' configured userconnections are already connected. System Administrator can configure toa higher value with sp_configure." No new connections can be made to theserver; however, the existing connections continue to function normally.We never see anywhere near 500 user connections in the system (it tendsto average around 350 connections). If we begin to disconnect users theserver continues reporting that the maximum number of users isconnected. Eventually running queries thru an open connection will hangand we have to resort to a hard reboot of the server as neither SQLServer will not shutdown nor will the operating system.The Server:Compaq Proliant DL380 with dual 863 MHz. processors (x86 Family 6 Model8 Stepping 3 GenuineIntel), 917,020 KB of physical memory, MicrosoftWindows 2000 Server (Version 5.0.2195 Service Pack 4 Build 2195), TotalVirtual Memory 3,138,688 KB, Page File Space 2,221,668 KBSQL Server:Microsoft SQL Server 6.50 - 6.50.479 (Intel X86). Some pertinentconfiguration settings: memory - 244100 (in 2K units), user connections– 500, RA worker threads – 3, max worker threads – 255We found one reference to the above error message in the MicrosoftKnowledge Base and that refers to a condition where the server has 2GBor more of physical memory with 1.5GB assigned to SQL Server. This doesnot pertain to our situation. Have any of you ever encountered thisproblem?I appreciate your insights.*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

I am unable to connect SQL Server Management Studio to any of the databases on my computer. At this stage I am simply starting the Management Studio and asking it to connect to a database I made a few months ago before this connection trouble arose. I'm specifying the server name "BENCHLAP" which is the name of My Computer, using Windows Authentication.
The error I get 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: Named Pipes Provider, error: 40 - Could not
open a connection to SQL Server)
The client is local. At least, it is if I understand correctly - the instance of SQL Server is installed on the same machine as the instance of IIS that I intend to use to test my web applications after we have resolved this issue, and the same machine as the one I shall use to view the application on.
I can ping the server if i type "ping -a BENCHLAP". It is successful
I think it also connects via telnet ok as well, by typing "telnet BENCHLAP 135"
All client protocols are enabled, as are the server protocols. Don't know if this is a security risk but I did it to try and solve the problem, to no avail. There are no aliases, according to the Configuration Manager.
The server itself is SQL Server Express 2005, runnning on Windows XP Professional. My anti virus software is AVG.
I'm afraid I don't know anything more, and have been researching this error for quite some time now.
Is anybody able to help me please?

Cannot someone please help me with following problem. I am trying to create a program to update a sql datbase from.NET 2003. I am doing this by using SQL Server Express 5. The problem is, is that when I run the program and click the button to view the table in SQL Express 5 I keep getting an 'System.NullReferenceException' and the table is not shown. When I look at the debug details it says that 'object reference not set to an instance of an object'.
Am not sure where am goin wrong as the connection is opened to the local server in SQL Express and I have created a connection object and initialised it to the address fo the datatable in SQL.
Please find below the code I am working on which shows the connection string in question and the table being called in button 6 which causes the exception.
Any help would be greatly appreciated....thanks

I have set up a database in SQL Server 2005 (The express version) and am trying unsucessfully to make a connection to it from MS Visual Web Developer 2005 Express version. I always get the same error:
"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this error 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 open a connection to SQL Server)"
How can I set up SQL Server to allow remote connections? I am trying to establish a connection from my web page to this database. Is there a user that I need to establish on the SQL Server side?

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 have 2 machines JAWS (publisher/distributor) and PSG (subscriber) on
trusted domains. MSSQL & SQLExec services of both machines run under the
local NT Administrator account
username: Administrator
password: XXXX
this NT Administrator account has the same username and password on both
machines. Their network protocols are named pipes. After I set up
replication following the sql manual, the LogReader, Distribution and Sync
tasks all report the error "unable to connect to JAWS". I'm wondering what
else I need to do. Any help are greatly appreciated. Thanks,

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!
