SQL Server Admin 2014 :: Remote Access To Named Instance
Jul 6, 2015
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'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 an existing 2012 default SQL Express. It's set up on a VPS managed by a third party. I have an administrator account on this 2012 Windows server. I'm not much of a sysadmin or a DBA but I get around. ;)
I've installed a new NAMED instance on this VPS and can not connect to it with client tools (SSMS). If I remote in, I can connect this way.
What steps might a seasoned DBA expect to make when getting a new named instance ready for the world.
Assign a port? Check the port?
Open the firewall for the port?
Will this new named instance listen on a different port than the previously installed SQL Express instance?
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].
We have transaction replication configured across multiple SQL instances and could find one of the replication (from publisher to subscriber) net transport sessions is happening via Named pipes rather than TCP. where to troubleshoot this issue and what action to be taken to make it happen via TCP.
I've been reading about the protocols and i've been trying to connect to my SQL SERVER using each one of the protocols, but i think I'm missing something, i dont have any problems using Shared Memory and TCP protocols, but I'm not pretty sure how to connect to my remote SQL SERVER using NAMED PIPES protocols. The books On Line of Microsoft refer that you can connect using this protocol using the next syntax: Connecting to a default instance by specifying a named pipe name:
APPHOSTpipeunitapp
Connecting to a named instance by specifying a named pipe name:
APPHOSTpipeMSSQL$SQLEXPRESSSQLquery
Connecting to default instance by name, forcing a named pipes connection:
np:APPHOST
Connecting to named instance by name, forcing a named pipes connection:
np:APPHOSTSQLEXPRESS
But I can't connect to my remote SQL SERVER, if i try the same with my local SQL SERVER i don't have any problems. I've been reading the articles so many times searching something about Named Pipes is only for local connections, but Microsoft say that it's posible to connect to a remote SQL SERVER, but i don't know how to do that. The firewall is disabled, I changed the APPHOST in the above syntax for the IP address of my SQL SERVER but it didn't work..
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).
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.
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.
How to set up a specific aliased instance name. I have installed two identical named instances on a server called LONPOCSQL. The instance names are FINPROD and FINREP, so when connection to them remotely I connect to LONPOCSQLFINPROD or LONPOCSQLFINREP. My question is how can I configure it so that I can connect remotely to the instances in by referencing them as FINPRODFINPROD and FINREPFINREP?
The reason for this is that I need to replace a very old system where the applications connect to the sql servers by referencing them as FINPRODFINPROD and FINREPFINREP respectively. I'm trying to set up a 2-node SQL alwayson AG cluster for HA+DR with one server in the prod DC and the other in DR. I need both instances to live one the same box.
1. As far as I'm aware SQL Aliases only work when the connection is local, remote connections fail 2. I can't create a DNS alias called "FINPRODFINPROD" and point it at a listener name as slashes "" are not allowed in DNS CNAMEs 3. My old boss once built a SQL 2008 R2 failover cluster with two instances on it called "lonsql40lonsql40" but there is no documentation on how he did it and I can't find anything on the web
I have built a SQL 2014 Always on Cluster. I need to create three Availability groups and listeners in the same instance. Do I need 3 separate IP address for each listener or one IP address can be shared for all 3 Listeners ?
When I setup my listener: ListenerA...Do I need to use the instance name in it?
ListenerAInstance01 or ListenerAInstance02 depending on which SQLNode is the "active" availability group?
Am I better off to use the same instance name for both nodes, since my goal is to have all databases on both instances in the same availability group and sync'd? When SQLNode1 migrates over to SQLNode2 I will need to update the instance name in my connection string on the listener from ListenerAInstance01 to Instance02? When I connect with SSMS do I just use: ListenerAInstance01 (or 02)?
How you are handling the replication of the many instance-level objects/items (logins, linked servers, server roles, database mail, operators, on and on) to the replicas in an AlwaysOn topology.
I'm especially curious about DBAs managing larger SQL Server environments. In my current environment, we have approximately 80 production SQL instances containing about 650 databases that require high availability and disaster recovery.
We use mirroring today and have a solid, home-grown solution for replicating the instance-level items from production to disaster recovery. AlwaysOn changes things a bit since we'll have multiple replicas and of course the database could be active on any one of those at any time. So my concern is about instance-level items being created in one instance but never deployed to the other instances participating in the AG group.
I am getting problem with remote login to the sql instance.
In machine Sql 2008R2 is installed as default later 2014 installed as named instance. Both TCP/IP, shared memory, namedpipes are enabled for both named & default instances. For the default instance I can used the remote connections but the named instance is not allowing remote connections.
We are in web site development company,Previously we don't have proxy configuration, after implementing Proxy , we have an issue to connect a remote database.
The error pops "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. Error 53".
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'm using ssms 2014, but got the same problem with 2012. I use ssms almost entirely on remote desktop sessions ( Windows 7, Server 2008R2, Server 2012 ). It may be related to having filtered job activity monitor windows open for hours, but about once per day ssms fails, and has to restart. Upon resuming usually only one of several queries is restored.
How you would calculate the average read/write latency experienced by a SQL Server instance during a specific time window in order to monitor this for multiple instances. From this MSDN blog, I know that you have to take multiple samples and do some calculations to get the correct latency.

However, the SQLServer:Resource Pool Stats object tracks these numbers per resource pool and we want to get one number for the whole server. Since there can be a different base value for each resource pool, you can't simply sum the numerator values together. Here's some sample data from a server that illustrates the problem.
object_name counter_name instance_name cntr_value cntr_type SQLServer:Resource Pool Stats Avg Disk Read IO (ms) default 307318919 1073874176 SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base default 25546724 1073939712 SQLServer:Resource Pool Stats Avg Disk Read IO (ms) internal 2045730 1073874176 SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base internal 208270 1073939712
I'm thinking I would need to do some sort of weighted average, but I'm not sure if that will result in the correct value. Here's the formula I am thinking about using currently before doing the calculation over time
I have windows 2003 (SP1) server with sql server 2000 (SP3) .
In the server network utility, I have enables only TCP/IP protocol and disabled the Named pipe protocol.
Now if I try to connect to the sql server from a remote machine, I get the message saying "unable to connect either server does not exist or ......".
I have configured the firewall to allow communication on TCP port 1433. It didn't help. I tried to disable the firewall completely, still it didn't work.
It works only if I enable Named pipe in the server's server network utility.
I set up the collector, and specify the Run As as my AD account in the Collector Set - Properties - General screen. My AD account is the local admin of the remote server.
However, the collector does not seem to work. Although the collecting set is shown as running, the The blg file stays at 64K. If I open it, there is nothing inside (no counter at the bottom). What did I miss?
We have applications connected to SQL using windows authentication. While having connection with Application user can also access to Database instance on the same time as well. We need to limit the access of user outside application.
I have SQL Server 2014 (Enterprise) on Server A. The service runs under DomainAAdmin.
The Client machine is B, User credentials DomainBUser.
DomainBUser has a share on B that contains a BCP data file. DomainAAdmin has full access to this file.
If I log onto A (the server machine) with either DomainAAdmin or DomainBUser credentials, and run SQL Server Management Studio with Windows Authentication I can run BCP sucessfully using the following:
BULK INSERT [MyTable] from 'Bsharedatafle.tsv' WITH ( KEEPNULLS , KEEPIDENTITY ) However, if I log onto B, (the client machine and the machine hosting the share) and try to run the same bcp command, I get "Access is Denied".
While running Sql 2014 upgrade advisor against a 2005 remote sql server. Below is the error im getting:
"Could not populate SQL Instances: System.Security.SecurityException: Requested registry access is not allowed"
Its able to connect SQL 2005 DB server and its also populating all the required Databases, but when i'm tring to click Run at the last step above error is coming. I even installed SQL 2012 upgrade advisor in my system and getting the same above error.
However if i use SQL 2008 upgrade advisor and connect to SQL 2005 server im not getting any error.The tool is generating successfully all the Pre and Post upgrade issues.
I'm running the tool with Run as administrator option. Is there any specific change i need to do in my system so that the tool runs successfully.
I have a user, who is trying log into the server, but everytime he gets this error saying something about the Group policy denies him access.
This user needs access and i'm trying to understand how to grant it to him.
I have been looking into how i can access the group policy editor, but the farthest i can get is the Local group policy editor. How do i make sure this specific user has access?
SQL server job or SP to deny access to an AD login for certain period of time to SQL server instance...i.e. to deny access to login ADxyz from 12 PM to 10 PM and revoke access to same login at 10:01 PM...
I've recently started working with a public sector organisation who have 4 clustered sql instances that has 80% of it's db mirrored.
Looking at the transaction log - it seems that a transaction log backup is a good idea as the log is 4x larger than the data file.But I'm not allowed access to the physical server to check onto which drive I can create the trn. No RDP, no vmware - let's be honest I'm not even allowed to launch cmd line Also the Server Manager informs me "We will need to carefully look at database backups if you guys want to start doing these backups on box, as that will break our off box backup routine (it will screw the transaction chain)."
I don't understand how backing up the transaction log could break the "transaction chain"?
