I have 2 PC's on my at-home network and when I use this Microsoft connect utility trick to test database connection, I can connect to the database in SQL Server Express on the PC that SQL Server Express is installed on with no problem.
But when I using the same utility trick on the other PC and try to test the same database connection, I get an error
Test connection failed because of an error in initializing provider. [DBNETLIB][ConnectionOpen server does not exist or access denied
I have Norton Security Suite on the PC where SQL Server Express is installed on, and added a rule to open port 1433 and even disabled "Smart Firewall" and get the same error. I even added a DB user (Used in .UDL utility shown below) with all rights, same error. Any ideas on a way to fix this?
By default SQL Express doesn't have TCP/IP enabled, and by default listens on a dynamic port when it is enabled. You can use SQL Server Configuration Manager to both enable TCP/IP and disable dynamic ports and configure SQL Server to listen on port 1433.
And once you do you can connect with just the hostname. No port number or \SQLEXPRESS required.
I have tried every conceivable permutation for hours to try to connect to a remote SQL Server 2017 using SSMS. I keep getting:
Logging failed for user xxx. (Microsoft SQL Server Error 18456)
I know SQL Server is running on the remote machines since I can log
in locally there using SSMS.
SQL Browser is running.
TCP/IP is enabled. There are no dynamic
ports in IP All.
I know the firewall is not a problem since I can
telnet to port 1433 from the remote machine, and I added the rule to allow access.
I have "Enable Remote Access" turned on in SQL Server.
I have both Windows and SQL Server Authentication enabled.
I have user mappings for the given databases.
I can connect locally using SSMS with the Sql Server Auth user/passwd that I am trying to use remotely.
When logging in from the remote client in SSMS:
I use an IP address for the server (although I can also browse to the server as I have UDP 1434 open).
I use SQL Server Authentication.
I looked at Event Viewer on the SQL Server machinee to see if it gives me more clues as to why the log in is failing, but it is worthless.
I saw this, but it is of no help.
What on earth could be left that is the problem?
I have a local installed SQL Server 2016 (Developer edition) installation on Windows 10 Pro. There is one named instance. I am a developer using MS SQL Management Studio and JetBrains DataGrip.
I just want my connections within my local machine to work with SQL Server over TCPIP using a SQL Server user account..! At the moment this only works using my Windows Authentication mapped to ServerAdmin
Named instance
RAXLENOVOT560\MSSQL2016MAIN
(authentication is mixed mode)
There are 3 issues that maybe linked:
TCP Port number does not appear to take effect within the Sql Server Configuration Manager.
The Sql Server Configuration Manager only shows limited properties on the Client Protocols/TCPIP settings. (please see screen shots)
Sql Server login user account does not connect via TCP due to an error. Login within local machine, local development from DataGrip to SQL Server.
1. TCP Port number
I have set this to 65321. However when I try and connect using this port no connection is made.
When I checked using the following SQL query I see the port number is actually 65514
SELECT DISTINCT
local_tcp_port
FROM sys.dm_exec_connections
WHERE local_tcp_port IS NOT NULL
results
local_tcp_port
--------------
65514
I change the port number in the config tool, restart ALL SQL Server services, reboot and still nothing works. Still listening on port 65514
Note I did not choose 65514, this seems to be a default from SQL Server.
2. The Sql Server Configuration Manager Properties Missing
Note the properties screen is limited only to a few options, there are usually lots more why is is? Perhaps due to running on Windows 10 Pro vs Windows Server?
3. Connection Login failure
Login from the local machine only.
I have opened the firewall for all the relevant SQL Server ports
TCP 1433
TCP 65514 (the forced sql server port)
TCP 65123 (what I would like to use)
UDP 1434 Sql Server Browser
I attempted login via a number of means
Sql Server Management Studio
Udl File
Java connection via DataGrip
Since opening the firewall, all the connections work but only if the hostname is 127.0.0.1, why can't I use the computer name? The connections also work if I use my Windows Login but NOT a SQL Server login
The login fails due to the error shown below from the SQL Server Log (which proves the TCPIP connection is reaching SQL Server).
Login-based server access validation failed with an infrastructure error. Login lacks connect endpoint permission

Some additional information:
Version
I am trying to achieve cross domain windows authentication access to SQL Server database. I am logged in locally as ABC\user, and SQL Server db is allowing access for XYZ\user. I tried to follow the instructions in the following link, in order for me to access the db without having to do remote desktop.
http://www.olegsych.com/2009/05/crossing-domain-boundaries-windows-authentication/
However, when I open SSMS locally and connect to db server using windows authentication, it gives me a pre-login handshake error. Please see the error image below.
Prelogin Handshake Error
Here are the things that I have troubleshooted:
1) Make sure that firewalls are all off.
2) Make sure that the network is not blocking traffic to and fro.
3) In SQL Server Configuration Manager, under SQL Server Network Configuration, all IP Addresses in TCP/IP protocols are set to "YES" for Active and Enabled settings.
4) Check that my local computer is using IPv4 and IPv6 is DISABLED.
5) I am able to reach SQL Server locally when using SQL Authentication.
I would appreciate for any suggestions.
As a consultant I got the same problem with both of my clients.
I've solved it by creating a .bat script with the following line. Just adapt it to your SSMS directory and user account.
runas /netonly /user:domain\username "C:\Program Files (x86)\Microsoft SQL Server\120\Tools\Binn\ManagementStudio\Ssms.exe"
I'm trying to create an ODBC connection to SQL Server, but when i do, i get error:
Connection failed:
SQLState: '01000'
SQL Server Error: 10060
[Microsoft][ODBC_SQL Server Driver][TCP/IP Sockets] COnnectionOpen (Connect()).
Connection failed:
SQLState: '08001'
SQL Server Error: 17
[Microsoft][ODBC_SQL Server Driver][TCP/IP Sockets] SQL Server does not exist or access denied.
Here's what I've tried:
not a firewall issue: tried with firewall on SQL Server turned off, and client turned off. Also able to telnet 1433 from client and that works fine.
not an access issue: I can login from many different computers, including the SQL Server itself using the account i'm using on client (using SQL Server authentication)
i can ping the hostname and IP address. (i've tried both)
The only thing i can think of is that the client computer is windows server 2003, and has various roles setup:
File Server
Application Server
Terminal Server
Domain Controller
DNS Server
I don't know why these services are setup, but for the time being i can't shut them off. Would it be any of these, and if so, is there a way to disable any of the aspects of them, that might be blocking SQL.
Any advise truly appreciated!
Found the issue. For some reason, even though SQL was not in use on the client, it was installed, and by going to All Programs -> Microsoft SQL Server -> Client Network Utility, i found that the protocal TCP/IP was using port 4717. I have no idea why that port was in use, and even further, i'm not sure why it would even matter - I was just setting up an odbc connection, and not using sql server (on the client) at all. Either way, I changed this to the typical port (1433), and like boom, ODBC connection works like charm!
Is it possible that the server in question has not been configured to use named pipes?
CAUSE
The most common reason that this connection attempt failed is
that this DSN or ODBC data source attempted to make a connection using
the TCP/IP sockets Net-Library, which is Dbmssocn.dll. Because the SQL
Server is not listening for incoming connections for TCP/IP sockets
clients, the connection fails. From ISQL/w, the second error message
stated above would be returned. The OS Error is 10061, and the
function call that failed was ConnectionOpen(connect()).
WORKAROUND
By default, SQL Server will listen for incoming connections
made by Named Pipes clients. Named Pipes is the default IPC mechanism
for clients to connect to a SQL Server version 4.2, 6.0, and 6.5
server. The Named Pipes DLL is Dbnmpntw.dll, and it should be located
in the Windows\System or Winnt\System32 directory. The TCP/IP sockets
netlib DLL is Dbmssocn.dll, and also should be in the Windows\System
or Winnt\System32 directory.The most common resolution to this problem
is to configure the client computer to connect using Named Pipes.
Configuring Named Pipes If the Microsoft Data Access Components (MDAC)
ODBC drivers have been installed on the computer, you can make this
change in the second step of the Create New Data Source wizard.
NOTE: You can download MDAC drivers from:
http://msdn2.microsoft.com/en-us/data/aa937730.aspx To configure the
client, start the Create New Data Source wizard, click the Client
Configuration button, and perform the following steps, based on the
version of the SQL Server ODBC driver you are using:
For SQL Server ODBC Driver version 3.50
Click the Net Library tab and use the drop down list box to set the
default network (Net Library) to Named Pipes.
On the Advanced tab, remove any advanced entries that reference the
server you are connecting to.
Click Done.
For SQL Server ODBC Driver version 3.70
In the Network Libraries section of the Edit Network Library Configuration
dialog box, select Named Pipes.
Click OK.
If you do not have the MDAC ODBC drivers installed, you can use the
SQL Server Client Configuration Utility tool to set the default
Net-Library to Named Pipes. You can install the client utilities from
the SQL Server CD from the i386 directory.

By default SQL Native Client seems to look for MSSQLSERVER instance. However, if you use SQLEXPRESS all connections through that will fail.
Very strange, but try installing your SQL Server with MSSQLSERVER instance name - it should work!
To create a new Data source to SQL Server, do the following steps:
In host computer/server go to Sql server management studio --> open Security Section on left hand --> right click on Login, select New Login and then create a new account for your database which you want to connect to.
Check the TCP/IP Protocol is Enable. go to All programs --> Microsoft SQL server 2008 --> Configuration Tools --> open Sql server configuration manager. On the left hand select client protocols (based on your operating system 32/64 bit). On the right hand, check TCP/IP Protocol be Enabled.
In Remote computer/server, open Data source administrator. Control panel --> Administrative tools --> Data sources (ODBC).
In User DSN or System DSN , click Add button and select Sql Server driver and then press Finish.
Enter Name.
Enter Server, note that: if you want to enter host computer address, you should enter that`s IP address without "\\". eg. 192.168.1.5 and press Next.
Select With SQL Server authentication using a login ID and password entered by the user.
At the bellow enter your login ID and password which you created on first step. and then click Next.
If shown Database is your database, click Next and then Finish.
Adding another check point to all the above answers. Valid if you are using a named instance of Sql Server ( ServerName\InstanceName)
Make Sure UDP Port is enabled in Windows Firewall with SQL Server Default UDP Port
Number 1434. If not present create a new incoming rule in Firewall for UDP 1434 Port and restart SQL Server Browser Services in SQL configuration Manager.
