SQL 2012 :: Named Instance With Specific IP / Port And Connect Using Browser
Jul 31, 2014
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.

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 am trying to setup a client alias to connect to a named instance on another server.
TITLE: Connect to 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 ..
By the way the SQL is SQL Server 2012 Ent and the O/S is Windows 2012 R2 minshell

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 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.

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 changed the Port of my named instance to use static port but still error log is giving two values ,why??
spid15sServer is listening on [ 'any' <ipv6> 50152].
spid15sServer is listening on [ 'any' <ipv4> 50152].
ServerServer is listening on [ ::1 <ipv6> 57518].
ServerServer is listening on [ 127.0.0.1 <ipv4> 57518].

I have a named sql instance on SQL 2012. The issue is that the clients is having problem connecting to it when the firewall is on, this is not consistent. The connection is fine when I disabled the firewall. When I turned the Windows firewall back on, it will work for awhile and it fails. I checked the SQL configuration manager and saw that a dynamic port is assigned to the named instance. I did put that in the firewall rule and unblock it. I also put TCP 1433 and 1434 as well as the browser service port, TCPUDP 2382 and it still didn't work.What is the best way to determine what port does the named instance are listening?

I have a new named instance (SQL Server 2005 x64 SP2 (Build 3159) Developer edition) setup with dynamic port selection. A default instance was also running on the server prior to the named instance setup.
SQL Server Browser service is running. Remote connections are configured on the named instance. But still remote clients can only connect when the port number is specified after the instance name (servernameinstancename,9999). Without the port number, "error 26 - Error locating Server/instance specified" is thrown.
Doesn't the SQL Server Browser service eliminate the need for clients to specify the port number? What am I missing?
Thanks.

Hi all,I'm having some trouble with connecting to SQL server instance latelywithout adding a port number. I used to be able to always connect toinstance without having to input SQLSERVER,portnumber. However nowthis is not the case. I doing this through an ADO connection object,and creating the connection string. Does anyone know if there was arecent Microsoft update or patch that would've cause this to stopallowing me to connect to a SQL instance without having to put in theport information? Thanks.

Hi,
I have two domains setup with two way trust in place. SQL server 2005 is installed in domain A.
Is it possible to log in to SQL server using machine account of a machine in domain B?
I have been told that you cannot access SQL server from another domain using machine account. But I cannot find any resource or references about it.
If this isn't the right MSDN forum for this I apologize, but any advice would be greatly appreciated.
Thanks in advance.

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.
Any help?

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!

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 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.

Version: SQL SERVER 2012 enterprise edition and SP2.
Due to one of the security reason, I have changed default port 1433 to another port number in configuration manger tools->protocols for MSSQLSERVER->TCP/IP --> IP ALL section mention another port number.
After restarted service, SQL SSMS able to connect server itself and new port number also LISTENING.
But SQL client SSMS not connected to one of the PC side after changing default port.

I have configured an instance to use static port, say 1435, and I turned off the Browser service.
I would like to know if I can use SSMSE to connect to the instance database directly. The instance is listening at port 1435 and accepting connection requests from other methods.
What I need to put into the "Server name: " field?
Normally, it would be like: <serverIP><InstanceID> with Browser turned on.
Now how do I add the port information to it, I tried
<serverIP>:<portNumber><InstanceID>
<serverIP><InstanceID>:<portNumber>
<serverIP><InstanceID> <portNumber>
None of them worked.
Any suggestions?
Thanks.

In QA we have a two-node cluster with four instances of sql. In trying to add a fifth, I was given an IP address already in use so the install hung.
I removed it from the cluster but it is still there in the registry etc on the node I was working on.
I read about using the maintenance tab of the sql server install to "remove a node" but the terminology is confusing. To me a node is a physical server and an instance is an instance of sql server -- not the same at all but they are often referred to as the same thing.
I definitely don't want to remove one of the servers from the cluster.

I create default instance on SQL Server 2012 Standard.
When I set it up, I changed instance id from 'mssqlserver', which is a default value, to 'new_instance_id'.
For some reason I want to connect to the instance with computername new_instance_id
Can I do it?

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 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 SQL Server 2000 Standard Edition (sp3a) running on a windows 2003 (sp4) Server.
It is a Production Server with 3 NAMED Instances and NO Default Instance.
Does anyone know if I can rerun the SQL Server Install and add a DEFAULT Instance to this box without disrupting the other Named Instances???

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

Hi all,
I have SQL Server in NT 4.0 which has two IP addresses. How to force the SQL Server to listen to specific IP address ? We can make client to listen to specific port & IP and let me know the way to configure SQL Server to listen only to specific port that will make to ensure that SQL Server can be communicated throught that specific port.
Your answer would be highly appreciated.

Setting: sql 2000 default instance installed. Installed a sql 2005 named instance.
I want to configure the sql 2005 instance to listen on a partcular TCP port. (I followed the instructions in KB article 177440.)
"SQL Config Manager" > Protocols for "Instance" > Right-click TCP/IP > Properties, I found about 5 IP addresses and an "IPALL" address (pretty good for a home machine with one NIC!).
Per the article, I removed the 0 from TCP Dynamic Ports and put the desired port number ("4567") in the port value, restarted the sql instance, and found this using "xp_readerrorlog" this:
......
.....
Server is listening on [ 'any' <ipv6> 4567].
Server is listening on [ 'any' <ipv4> 4567].
.....
.....
Server is listening on [ ::1 <ipv6> 49277].
Server is listening on [ 127.0.0.1 <ipv4> 49277].
It looks like my instance is now listening on the desired port (success) but also, still, using a dynamic port. Did I do something wrong or can the dynamic port simply not be eliminated?
TIA,

Hi All,
I am using SQL Server Express to connect to the network using VPN on a local machine. I have done the following..
a.) Enabled the remote connections for the Express Instance and rebooted the machine.
b.) Connected to the machine with Express Edition locally and can also connect other SQL Server instances from it to verify connectivity.
c.) Yes, SQL Browser Service is running.
d.) Firewall is not turned on, so I do not have to configure any exceptions.
Now here is the big problem: When I browse for SQL Servers on the network the machine does not show up on the list, i.e "macinenameSQLExpress". I had uninstalled and reinstalled the Express edition and rebooted the machine several times with no luck on the SQL Express Instance showing up on the browser list. I even changed the default instance name to "machinenameMACHINE1" on one of the reinstalls. However, I can connect to other SQL Instances from it. But, I cannot connect to it from other machines since its not registered on the network. I have been working on this for the past few days by looking for a solution via this and other forumns. Is there some setting somewhere that I am missing that prevents this instance from not showing up on the browser list. This issue with SQL Express Edition is baffling as well as frustrating and any ideas that can resolve this issue is very much appreciated.

So, here is the scenario. I have a server that is running a MSDE 2000 instance (8.0.2039). Runs just fine. I install another database, this one is SQL 2005 Express (9.0.3042). Both are installed as part of application setups. Now, for various reasons, I have to uninstall the MSDE 2000 application and reinstall it. After the reinstall, the SQL Browser service no longer enumerates the MSDE instance, only the 2005 instance. As a workaround I fixed the MSDE port on the server and the clients, and it works fine. It also works fine when the application is run from the local computer without a fixed port.
Any suggestions?
Thanks,
Mark
