Cannot Remotely Access SQL Server Standard Named Instance
Oct 10, 2006
Good Day,
I am creating a SQL Named instance as a testing environment. This instance is on the same physical box as my Development environment, both are SQL 2005 standard edition. From the server in Management Studio, I can load, and interact with both instances. From a remote connection (e.g., my pc) I cannot access the named instance. I am getting the following:
Connect to Server
X Cannot connect to <server><named instance>
Additional Information
An error has occured while establishing a connection to the server. When connecting to SQL Sever 2006, 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)
I have checked, and rechecked the server settings for this named instance, and remote connections are set to "allow" I have enabled TCPIP and Named Pipes prototocals, and have ensured that my firewall is allowing the "listenting port" for the named instance, and have even tried turning off my XP firewall during testing.
I am sure that I have probably missed something, and have searched the community but only have been able to find resolutions that I have already tried. Is there more?
Thanks in advance for any help and guidance you can provide.

I try to connect from a pc to a SQL Server on another pc. Both pc’s are in a workgroup. I want to connect from a Windows Forms application to a named instance on the other computer. By now I have been able to connect from one pc to SQL Server on the other with tcp:smurfin, 52782.
I want to be able to use servernameinstancename (instead of portnumber) to make a connection in a Windows Forms application.
I’ve checked / tried te following:
•In the properties of the instance, tab Connections, the option Allow Remote Connections is enabled
•In Configuration Manager: TCP is enabled
•The service SQL Server Browser is started
•On the tab IPAddresses, in the section IPAll, there is NO portnumber for TCP Port. And TCP Dynamic Ports has the nummer 52782
•I have created un inbound rule for port 52782 and also for 1434 (SQL Server Browser). And to be on the save side: a rule for 1433 as well.
•Restarted the service
If I run the following code in SQL Server, that same port number (52782) is returned:
EXEC xp_ReadErrorLog 0, 1, N'Server is listening on', N'any', NULL, NULL, 'DESC'
GO
SELECT local_tcp_port
FROM sys.dm_exec_connections
WHERE session_id = @@SPID
[Code] ....

I have a named instance of MSDE running on my windows 2k3 web server. I can connect just fine using ODBC to that DB whailst I am on the server.
I would like to be able to create an ODBC connection from my local machine (running Windows XP pro) to the MSDE database on my server but I can't get it going.
I have heard that I need to edit the registry but a Google search warns that this could be a vulnerability...
How do I do it without compromising the security of my web server?
TIA

Hi,
I have sql2005 sp1 active-active installation.
I've fixed the named instance port.
I can't reach it from clients with i'ts name (servernameinstancename) .
I manage to rech it only by using servername, ip-port.
The sql browser has the following error:
"The configuration of the AdminConnectionTCP protocol in the SQL instance GILBOACL is not valid."

I have installed and configured a 2nd instance of SSRS 2005 Standard Edition SP1 on a Windows Server 2003 Standard Edition SP2. The 2nd instance is using it's own database and virtual directories under the default website. All configuration steps ran without error. I have no problem accessing the 2nd instance virtual directories via IE. When I connect to Reporting Services via Management Studio, it gives me no options for which instance to access and connects to the default instance. How do I connect to a 2nd named instance of SSRS via Management Studio? I've found no documentation in BOL related to this.

This is a slight re-stating from an older thread, which I think warrants some new discussion. The answer has always been that system administrators should have full access to everything on a system, including databases.
Although that is a logical position for internal IT departments it doesn't quite fit the model of systems with outsourced or external system support.
"If you don't trust your DBA, then you need a new DBA. They are in a position of authority for a reason and restricting that authority makes it impossible for them to do the job they are hired to do."
What about scenarios where you have local machine administrators that should NOT be given access to private data in a secured database, even though they need to be able to access and maintain everything else? And unfortunately some regulations are written about access to stored data whether encrypted or not...
In the modern world of Sarbanes-Oxley and PCI-DSS/CISP it is no longer so cut and dried. Especially where companies have software/hardware support contracts with third parties that require administrative access to other aspects of the systems.
So accepting that you might need someone to have administrative level access to the box but they should not be able to view the contents of a database installed on that box, what would you do?
Is there a way to create an adminstrative group that does not allow access to a specific named instance of SQL?
Is there a way to revoke access for one member of the administrators group only?
Thanks,
Ted

The box I am trying to connect to is running two instances of SQL Server.
There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'.
I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" />
However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried:
<add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" />
but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used:
<add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" />
but this doesn't work either.
Am I mssing something here? Any help much appreciated
Thanks...

I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.

I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.
I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.
I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.
Should I be able to connect as serverinstances for a named clustered instance in 2012 ?

I had a big problem on connecting sqlserver remotely from other machines on the network .....
From any computer in the network i wanna to register the instance of the sqlserver from the enterprise manager ..... the server instance doesn't appear within the available sqlserver list (the servername which equal to my machine is the only one that appear) ..... when i manualy write the servernamealias manually and i choose the connection type and then i write sqlserver username and password and then finish he give a message to me that access denied or sql server doesn't exist ... !!

Someone please help me before I loose all of my hair :mad: !!!
I have two machines, a Windows Server 2003 machine running an SQL Server Standard Edition database instance and client tools (Enterprize Manager etc.), and a workstation PC running Windows XP SP2 which has just the SQL Server client tools (not an actual DB instance).
I'm trying to use the Enterprize Manager client tool on my WinXP machine to remotely connect to the server instance on the server PC (via 'New SQL Server Registration' option). Everytime I do this I get the following error message:
Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server Connection.
Now I've tried using different usernames and passwords. I have login details for my SQL Server set to use Windows Login rather then SQL Server login, so I tried remotely connecting with the username and password for the server PC, tried 'sa' with server password, even tried setting up a new user on the server and logging in from the client with that, no luck. I've opened up correct ports 1433 on both PCs, even disabled the windows firewalls algother. Both server and client have SP3a installed, WinServer2003 has SP1 and XP SP2.
So I'm at a loss to how to remotely connect to my SQL Server. FYI I know the server itself is working fine because I can connect to it using Enterprize Manager/Query Analyser on the local machine. Any ideas? Many thanks for your help!

Thanks for Microsoft's Windows XP Service Pack 2 and Windows Server 2003 that make the security much stronger. However, besides the invisible benefit so far, I have become the victim of this security policy.
I have several named instances of SQL 7/2000 installed in my machine. They are not visible out of the Microsoft new fire wall. I need to access the instances from outside the fire wall, but I don't know which port I should open for the instances.
From SQL online, the default instance of SQL server is connected through TCP/IP by default port 1433. I could successful open that port and made the default instance visible to outside. However, the port 1433 doesn't work for the named instances. SQL online said, the port for named instance is dynamically (by default) chosen the first time the instance is started. So, actually, I have no way to know the port.
Is there anyway that I can check the database or somewhere to get the port that is used by the named instance?
Thanks for any input and recommendation.

I have a java compiled jar file, which accept the connection string as follows: -Uusername -Ppassword -Sservername:port
This string works fine with the default instance of SQL Server, I mean as long as you supply the name of the SQL Server as 'SQLServer', but if I want to run it against the named instance of SQL Server like 'SQLSERVERNamedInstance' then the connection is failing, giving me the unknown host error. Any idea why?

We have installed SQL 2000 SP4 on Windows 2000 Server. We created named instances on the SQL server.
When trying to connect to named instances from a remote sql client which is on windows 2000 and windows 2003, its throwing an error message saying that remote connections are disabled.
But, remote connections are enabled on the SQL server.
After changing the component services settings on windows 2003 where sql client is installed, we are able to connect to named instances.
But, after applying the same settings on another windows 2003 machine, we are unable to connect to the same instances.
We have another machine where we installed SQL 2005 on windows 2003 SP1. When trying to connect to named instances from any remote client, its throwing an error message saying that remote connections are disabled. But, remote connections are enabled in SQL server settings. We tried connecting to the instances by changing the component services settings but still we are facing the same issues.
Can you please help me on above issues?

Hi, I have a task in hand to migrate (upgrade) from SQL2K named instance to SQL2K5 default instance. There are many intranet applications touching current SQL2K. I would like to perform this upgrade such that I don't have to touch any application code - meaning I don't have to change the connectionstring to point to new Default instance. How can I achieve this?
So, in otherwords, here is what I want to achieve:
Current Server: SQL2K: SERVER_AINSTANCE_A (named instance)
Upgraded Server: SQL2K5: SERVERB (default instance)
If I have both default, I could achive this by setting up DNS alias after migration done so that any call for SERVER_A would point to SERVER_B. But in my case, I don't have SERVER_A, I have named instance. Is there any solution?
Regards,
Vipul

I am trying to perform a distributed query however have a situation I haven't dealt with before the linked server I add to do the query is a named instance (DVD_NASDOMINO). How would I specify this in a query as in the FROM part in a sql statement. I tried the obvious DVD_NASDOMINO.qlsdat.dbo.stmenqry and DVD_NAS.DOMINO.qlsdat.dbo.stmenqry.
Both returned errors in the query.
Thanks for the help.

I am trying to set up a Named Instance of SQL 2000 on the same machine that has a default instance of SQL 7.0. The setup always completes and I am able to register the Named Instance of the SQL Server with which it was installed on. However, when I try to connect the users to the database, with both windows and SQL authentication, I receive a SQL server not found error. I have tried an alias setup as well as physically specifying the port number in settup up an ODBC connection.
Has anyone ran into similar problems?
Also, has anyone been able to successfully complete the process as mentioned above?

I have a server with sql server 2005 installed as the default instance -- I have a piece of software that needs SQL2000 to be the default instance. Is there a way other than install new sql2005 named instance and move databases to rename my SQL2005 instance from <machinename> to <machinename>sql05 for example?

Hello, I am new to SQL Server Express, I am trying to upscale my database/Application to a SQL Server/Application with C#. All I want is to create a SQL Server service on my Office Server and manage it via my station. But I keep getting this error:
TITLE: Connect to Server
Cannot connect to SERVER.
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. (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.) (Microsoft SQL Server, Error: 10060)
The thing is that I went on the Server in the Surface Area Manager, I allowed IP and and Name pipes on network. Still does not work.
When I open the Manager from my station, I see the Server but keep getting this error.
Can someone please help me. Thank you

I have opened up a port on a remote SQL instance and can see that the port is LISTENING when using the PortQry tool. I have also set the TCP port in the TCP/IP properties in the IPAll section for that instance, yet I am unable to connect and get an error of
Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=1; handshake=14998; (.Net SqlClient Data Provider)
I have done this on other instances, although they were default instances, and it has always worked fine.

We have 3x instances of SQL Server 2012 installed on a single remote server - there's the default MSSQLSERVER instance, then INSTANCE01 and INSTANCE02. I can remotely connect to the default MSSQLSERVER instance through SSMS, but I cannot connect to either of the additional named instances (INSTANCE01 or INSTANCE02).Â
For example, if I try to connect to "sql.domain.com", I can successfully access the default instance on the remote server. If I try to connect to "sql.domain.comINSTANCE01", I get an error stating
"A network-related or instance-specific error occurred while establishing a connection to SQL Server".
However - if I try to connect to "sql.domain.comINSTANCE01, 49301" (where 49301 is the TCP Port for the TCP/IP Protocol for this SQL Server instance), I am able to successfully connect.
This leads me to think that there's a communication issue with the SQL Server Browser service running on the remote SQL Server and my workstation.Â
The following items have been verified:
SQL Server Browser is running on the remote SQL ServerWindows Firewall has been disabled on the SQL ServerTCP Ports 1433, 1434, 1954, and 49301 have been opened up on the remote destination's firewallUDP Port 1434 has been opened up on the remote destination's firewall.

I have TWO named SQL Server instances (on the same machine) and I need to know the port of each of them, how can I do that? Is it write to check the following:
Which one to take: "TCP Dynamic Ports" or "TCP Port"? and what is the difference between them anyways?Â
Can the two instances (or more)Â on the same machine use the same port?!

Several applications in out environment use Microsoft access to access the SQL server databases. Our new SQL Server 2005 instance is a named instance. We would like to create a .reg file to update the individual workstations as part of the migration. For some reason the .reg file with a named instance does not work. If the entry is created through the GUI it works. The server drop down does not show the named instance, only the server name but if you type the servernameamed_instance it finds it ok. Here is an example of what works and what does not. Any ideas on what the problem might be?

I have two instances of SQL Server on the same PC:
Default instance: SQL Server 2000
Named instance with name €œMS2005€?: SQL Server 2005.
Also I have another SQL Server 2005 on another PC.
I created a .NET 2.0 Compact Framework application that connects to the database and executes simple query. This application can connect to any instance of the SQL Server when it is executed on the PC (not on the server). But the problem is that when I try to execute the application from the windows CE 5.0 device, the application can only connect to the default instance (SQL 2000 and 2005) and can not connect to the named instance (Name: MS2005).
Is it some kind of limitation of the SqlClient library for the compact framework?
Below are the code and connection strings:
string connectionString = €œServer=1.1.1.1;Database=DB1;Uid=sa;Pwd=€?
string connectionString = €œServer=1.1.1.1\MS2005;Database=DB1;Uid=sa;Pwd=€?
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open(); //This is the point where exception is generated
using (SqlCommand command = connection.CreateCommand())
{
command.CommandText = "select count(*) from users";
object result = command.ExecuteScalar();
Console.WriteLine("Result: [{0}]", result);
}
connection.Close();
}
Thank you for your time and advice.

We are trying to quickly put together what needs to be accomplished to install a named instance of SQL Server 2000 on an existing production server (also running SQL Server 2000). It appears as if the install will require a reboot. Can the reboot be postponed until after-hours without impacting the default instance of SQL Server?
Also, I see that if certain services are stopped prior to installing sp4 that you can avoid a reboot. However, if we are unable to stop these services (DTC, for example) without impacting the default instance of SQL Server, will the default instance of SQL Server experience any issues if we postpone the post-sp4 reboot until after hours?
Thanks!

I installed SQL Server 2005 recently on a cluster. I didn't go for the default instance and instead I named the instance option. Now I would like to migrate everything from the named instance to the default instance, which I haven't yet installed.
Is this an easy process? What about the logins and the maintenance plans and jobs? Is there anything else I need to be aware of?

Hi
I've never had to do this, but when I downloaded the Web Workflow Approvals Starter Kit, it requested that I install the database into a User Instance of .SQLEXPRESS.
Now the problem is, I've installed it onto a default instance, so I was wondering whether you can create a named instance on top of a default instance... and if so, how would you do that?
Cheers
Chris
