DB Engine :: Cannot Connect To Remote Named Instance Of Server
May 8, 2013
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've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamics FINANCE) 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]Â 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 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?!
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
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?
I installed sql server 2005 express on a server with window server 2003 SP1 and tried to connect it from a remote computer with vista installed.
I have already enabled named pipe and tcp/ip protocol for instance SQLEXPRESS on the server, and started sql server browser as well. Of course, I also enabled local and remote connection using tcp/ip and named pipe by sql server surface area configuration tool.
In this senario, I can connect to server locally or remotely by tcp/ip and connect to server locally by named pipe(c>sqlcmd -S \192.168.1.100pipeMSSQL$SQLEXPRESSsqlquery -U * -P *), but I can not connect to server remotely using same command line.
According to some article from MSDN, it might be caused by firewall, but I already disabled my firewall. Moreover, I used tools like makepipe.exe and readpipe.exe, they didn't work too. Why the 2 computers can't create connection using named pipe protocol.
I am trying to setup a client alias to connect to a named instance on another server.

I have set up the alias on the server and as expected it works. On the client side I have used the SQL Server Client Network Utility to configure the client side alias but no luck
I am using TCP/IP with a specific port ..

I recently installed SQL Server and Visual Studio. When I went into SQL Server, I could only connect to a SQL EXPRESS Database engine. I need to access the full Database. I tried disconnecting it, uninstalling/reinstalling. Now I cant connect to the SQL EXPRESS DB Object. There are no SQL Server services running.
Hi, I am struggling connection to a named instance of SQL 2000 (SP4) from another machine but without any success. I get an error message saying that the server does not exist or access is denied.
The security configuration in this named instance is the same as the default instance (also 2000) and the remote machine can connect to it successfully.
I also configured the aliases in Client Network Utility in the client machine and set the server (machine) name and the port number used by the instance - but no help.
I use osql and Query Analyzer to connect to it, but I cannot connect by any of them.
Connecting locally, in the machine where the instance is installed, is successful.
The same behaviour appears when I try to connect to another instance on the machine which is 2005. Something with the named instance is problematic.
Hi- I am hoping someone can help me or shed some light on an issue I am having. I have recently moved to a dedicated server with MSDE installed on it. The server was installed as the default instance and I changed the password to the SA account. I then copied my entire SA database over to the new MSDE database and everything was working good so it seemed. I believe at some point during copying of the data, or after installalling an application the SA account begain to fail and the password was changed. I have no idea how this happened, and better yet when I tried to change it logged in as the administrator with OSQL it told me I did not have sysadmin rights (I tried multiple Windows NT Auth logins and still got this error trying to change the password). So... I reinstalled MSDE and created a named instane. I then attached the mdf/ldf files to my named instance and am able to connect ok from a .NET application directly to my new MSDE Named Instance database. Sounds like everything is great right? Not really, I can't figure out how to connect through enterprise manager and its driving me CRAZY! 1. I CAN connect via any .NET app and a connection string 2. I CAN connect via the server with OSQL 3. I CAN connect via the web based enterprise manager (which is very limited and a freeware ASP app). 4. I CANNOT connect via enterprise manager. I have verified from the (SVRNETCN.EXE utility) that the port is open and have tried connecting to MY_IPADDRESSNAMEDINSTANCE but no luck. One additional side note, when I wasn't using a named instance I had no problems connecting through enterprise manager to my default MSDE instance. Any help would be grealy appriciated, this is driving me nuts! -Chad
I'm trying to configure a named instances of SQL Server 2012 SP2 to have specific IP addresses and listen to that IP on port 1433. Alongside this, I have the default instance running on a different IP and listening to that on port 1433.I've managed to get them configured so that they are reachable using the IP, and looking at the log for each they are listening correctly on that IP on port 1433; in addition, the default instance connects fine using the SERVERNAME.However, when I try and connect to the named instance using the SERVERNAME/INSTANCENAME syntax, I receive the following:-
"Cannot connect to SERVERINSTANCE. Instance failure. (System.Data)"
Configuration for the TCP/IP protocol for that instance is as follows:-
Protocol Tab
Enabled= Yes Keep Alive = 30000 Listen All = No
IP addresses Tab
IP1 Active = Yes Enabled = Yes IP Address = 10.1.1.1 TCP Dynamic Ports = 0 TCP Port = 1433
[code]...
The SQL Browser service is running and prior to switching off Listen To All, I could connect to the instance remotely using the instance name.
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 recent installed a named instance of SSRS 2005 on a remote server. The server has a side by side install of SSRS 2000 and SSRS 2005, with the SSRS 2005 being a named instance. The server also has SSL and MS Sharepoint Portal Server installed.
When I try and connect to the SSRS 2005 instance with my client install of Mangement Studio, I get the error message:
"The underlying connection was closed: Could not establish a trust relationship for the SSL/TLS secure channel. (System.Web.Services)
Additional Information: The remote certificate is invalid according to the validation procedure. (System)."
Obviously, this is a SLL issue, but, not being a security guru, I have no clue on how to fix this. I do know the certificate is valid, not expired and properly working. Both installs of SSRS are set up using the SSL certificate. Also, I am not connecting to SSIS with Management Studio, as I heard there is a bug connecting to both SSRS and SSIS at the same time.
I have installed a SQL Server 2005 Standard Edition instance with SSIS on Window Server 2003 x64. From my PC, I am able to connect to the Integration Services on the server using Windows Authentication but not with a local SQL login - and the option to change authentication methods is greyed out.
Is it possible to remotely connect to SSIS using a SQL login rather than a Windows login? If so, any ideas or references for configuring it as such?
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?
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.
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)
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?
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.
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?
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.
If i initially installed SQL Server 2005 Developer Edition using the "default instance", how do i create an additional (new) SQL Server 2005 (90) "named instance" without reinstalling SQL Server 2005?
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?
Windows Registry Editor Version 5.00 - Does NOT work
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.
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?
