I have a trivial VB script which I am using to connect to a MySQL database on a Windows Server (2012 R2).
It's all super simple, out of the box "connect to MySql example" stuff.
I have verified that MySQL is listening on all local IPV4 addresses. I can connect with MySQL workbench with the same parameters. Yet I get a weird error when connecting via my program:
An address incompatible with the requested protocol was used
My connect string is as follows:
"server=127.0.0.1;database=test;uid=xx;pwd=xx"
It appears the connection tries to use IPV6 when connecting. How is this possible?
I suspect some kind of firewall is modifying or blocking my network connection, but it is a "new" machine for me and I don't know what's installed.
The problem was due to an old MySQL Connector DLL (MySQL.Data.dll) version which was either incompatible with Windows (hence the networking error message) or the version of MySQL I'm running. After upgrading the dll, the connection worked properly.
This may help out someone who has a similar problem, as the error is highly misleading.
I successfully installed MySQL server (I can connect to it manually through the MySQL shell). When I try to establish a connection through MySQL Workbench, the test connection goes through as well. But when I try to view the server's info or interact with the server, an error message pops up that says, "Current profile has no WMI enabled." I have searched for a solution to this problem, and found a few threads like this one: https://www.quora.com/MySQL-Workbench-How-can-I-solve-the-Current-Profile-Has-no-WMI-enable-error-message. However, I just can't find the 'Manage Server Instances' dialog or button anywhere. I am running workbench version 6.3. If anyone has run into this problem then I would appreciate a workaround.
It's unusual that you get that error again. I haven't heard since years of such a problem. Anyway, the solution is still to configure the connection properly. That "configure server instances" link is very old (from WB 5.x). Instead look for the connection editor (titled: Manage Server Connections). You can open the dialog either via the main menu or the small wrench button on the homescreen:
I downloaded and installed the driver setup file, DB2OLEDB.exe, from here:
http://download.microsoft.com/mwg-internal/de5fs23hu73ds/progress?id=HYLbKUfGNl
Using the connection string that worked on another PC, I tried to create a Connection Object in an SSIS package. When I tested the connection I got this error:
Test connection failed because of an error in initializing provider. A TCPIP socket error has occurred (10057): A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.
Any suggestions on what the cause of this error is and how I might resolve this issue?
By the way, when I use the DB2 Configuration set up utility and test a connection from within that, I am able to successfully connect.
What other info can I provide to help you answer this question?
Thank you
Could this be related to a blocked port?
If you follow all the steps illustrated here: http://www.bidn.com/blogs/PatrickLeBlanc/ssis/700/connecting-to-db2-using-ssis do you still get the same result?
Maybe a silly question, did you restart the computer after the installation?
Are you an admin user on one machine and not on the other?
You could try to verify the port connectivity with a quick telnet command:
telnet your-db-host your-db-listening-port
If it connects, that one is off the list.
Doing some research I've found two possible fixes.
The first link suggests calling BeginReceive after the EndAccept logic is complete. Are you using script code, or just using the GUI without any scripting?
TCP async sockets throwing 10057
The second link points to drivers / software on the PC. It could be that you are missing a windows update or have faulty hardware / drivers.
I think this is less likely the case since you could connect to a different machine with the same connection string(?). Can you verify this is a valid statement?

If you could show the connection strings used for both the working and non working, and give a little more detail about The "Other PC" in comparison to the non-working PC... that would be helpful =]
If neither of the posts I've linked are the solution, this specific Google search has proven to yield some seemingly helpful results
"socket" "10057" "no address was supplied."
Let me begin by saying, I am aware of this thread and others around the web that seek to trouble shoot this issue.
The solutions posted there do not apply to my issue. I have spent 5 hours trying to resolve this before deciding to ask the question.
The problem:
When I attempt to log into SSMS (or connect from a java application) using SQL Authentication I get this error:
A connection was successfully established with the server, but then an
error occurred during the login process. (provider: Shared Memory
Provider, error: 0 - No process is on the other end of the pipe.)
(Microsoft SQL Server, Error: 233)
Although it does work, it is not an option for me to use integreated authentication.
The database I am attempting to connect to is on the same machine as my SSMS instance. There is no network, this is a stand-alone system.
NAMED PIPES is ENABLED in my configuration, I HAVE rebooted since, TCP IP is a higher priority than named pipes in my configuration.
I have even gone as far as to uninstall SQL Server and reinstall it, to no avail.
The details of my SQL Server instance are as follows:
Microsoft SQL Server Management Studio - 10.0.2531.0
Microsoft Analysis Services Client Tools - 10.0.1600.22
Microsoft Data Access Components (MDAC) - 6.1.7601.17514
Microsoft MSXML - 3.0 5.0 6.0
Microsoft Internet Explorer - 9.0.8112.16421
Microsoft .NET Framework - 2.0.50727.5466
Operating System - 6.1.7601
Configuration details are as follows:
http://i45.tinypic.com/vxdz7c.png
http://i45.tinypic.com/vxdz7c.jpg
I connect from java using this code.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl = "jdbc:sqlserver://localhost;database=AdventureWorks;integratedSecurity=false;User=JIMBO; Password=JIMBO;";
Connection con = DriverManager.getConnection(connectionUrl);
But please remember, this error also occurs when I atttempt to log in to SSMS directly.
Thanks in advance.

To force TCP/IP being used replace localhost with 127.0.0.1 in your connection string.
As you are using a username and password make sure SQL authentication is enabled. By default only Windows integrated is enabled on sqlserver 2008.
With SqlServer authentication keep in mind that a password policy is in place to enforce security.
Forcing the TCP/IP connection (by providing 127.0.0.1 instead of localhost or .) can reveal the real reason for the error. In my case, the database name specified in connection string was incorrect.
So, here is the checklist so far:
Make sure Named Pipe is enabled in configuration manager (don't forget to restart the server).
Make sure SQL Server Authentication (or Mixed Mode) is enabled.
Make sure your user name and password are correct.
Make sure the database you are connecting to exists.
My resolution was to login using the Windows Login then go to security>Logins locate the troubled ID And retype the used password. The restart the services...
Adding "user instance=False" to connection string solved the problem for me.
<connectionStrings>
<add name="NorthwindEntities" connectionString="metadata=res://*/Models.Northwind.csdl|res://*/Models.Northwind.ssdl|res://*/Models.Northwind.msl;provider=System.Data.SqlClient;provider connection string="data source=.\SQLEXPRESS2008R2;attachdbfilename=|DataDirectory|\Northwind.mdf;integrated security=True;user instance=False;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>
This problem was caused for me by this error which appeared just prior in the application error log.
"A read operation on a large object failed while sending data to the client. A common cause for this is if the application is running in READ UNCOMMITTED isolation level. This connection will be terminated."
I was storing PDFs in a SQL table and when attempting to SELECT from that table it spit out that error, which resulted in the error mentioned in your question.
The solution was to delete the columns that had large amounts of text, in my case Base64 encoded files.
perhaps this comes too late, but still it could be nice to "document it" for others out there.
I received the same error after experimenting and testing with Remote Desktop Services on a MS Server 2012 with MS SQL Server 2012.
During the Remote Desktop Services install one is asked to create a (local) certificate, and so I did. After finishing the test/experiments I removed the Remote Desktop Services. That's when this error appeared (I cannot say whether the error occured during the test with RDS, I don't remember if I used/tried the SQL Connection during the RDS test).
I am not sure how to solve this since the default certificate does not work for me, but the "RDS" certificate does.
BTW, the certificates are found in App: "SQL Server Configuration Manager" -> "SQL Server Network Configuration" -> Right click: "Protocols for " -> Select "Properties" -> Tab "Certificate"
My default SQL Certificate is named: ConfigMgr SQL Server Identification Certificate, has expiration date: 2114-06-09.
Hope this can give a hint to others.

For me it was because only Windows Authentication was enabled. To change security authentication mode. In SQL Server Management Studio Object Explorer, right-click the server, and then click Properties. On the Security page, under Server authentication, select the new server authentication mode, and then click OK.
Change Server Authentication Mode - MSDN - Microsoft

I had the same issue, after multiple trial of suggested solution on this site and others, I found a solution for my scenario. The account was locked out
How to Check if the account is Locked out...
Login to the server using higher privileged account (like SA or admin rights)
Expand security ==> select the login name ==>open the property window of the login ==> select the status page on the property window
Make sure This 3 Things
1, permission to connect database is GRANTED
2, Login is ENABLED
3, Status
SQL server authentication
Login is not locked out (Uncheck the box)
Thanks

I just executed connection.close() by adding it as first statement and it was solved. Then i removed the line.
One follow up to this. I had installed SQL Server 2014 with only Windows Authentication. After enabling Mixed Mode, I couldn't log in with a SQL user and got the same error message as the original poster. I verified that named pipes were enabled but still couldn't log in after several restarts. Using 127.0.0.1 instead of the hostname allowed me to log in, but interestingly, required a password reset prompt on first login:
Once I reset the password the account worked. What's odd, is I specifically disabled password policy and expiration.
Another cause is if the user's default database is unavailable.
I had an account that was used for backing up two databases. When the backup user's default database was taken off-line, the "no process on the other end of the pipe" error started.
Came here looking for a solution to a similar issue, which I just introduced by changing Schannel settings of our IIS server using "IIS Crypto" by Nartac... By disabling the SHA-1 hash, the local SQL Server was not able to be reached anymore, even though I didn't use an encrypted connection (not useful for an ASP.Net site accessing a local SQL Express instance using shared memory).
Thanks Count Zero for pointing me in the right direction :-)
So, lesson learned: do not disable SHA-1 on your IIS server if you have a local SQL Server instance.
For me the issue seems to have been caused by power failure. Restarting the server computer solved it.
Actually I'm having more than one problem...but all of it has to do with connecting or working with the MySQL database...First you can see one of the errors on my website and no matter what you choose it seems to just say it can't connect to the database...I've configured a configure.php file to allow files to connect to the MySQL database...see the website here:
http://netsurfer123.byethost11.com/index.php
Then when I try to log-in to the Admin area of my MySQL database it just says:
phpMyAdmin - Error
Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.
Please let me know what I can do to correct these errors...and thanks very much in advanced for any helpful response/s.
First you need to check if the MySQL server is actually running. Use a command such as
/etc/rc.d/init.d/mysqld status
Or similar for your system if possible.
Did you check the web server log file? Does it contain errors as indicated by phpMyAdmin?
Your site is simply unable to connect to the database to which it's trying to connect. This could be for any number of potential reasons:
Is the database running?
Is the database accessible by that machine? (Maybe there's a firewall in between the two servers, if they're separated?)
If the database is on that same machine, are you connecting to it properly? (Maybe it allows only certain connection methods, such as a socket vs. the loopback address?)
Is your connection string correct? Maybe the login is failing?
Check your PHP logs, your Apache logs, your MySQL logs. One of them is complaining about something and it's probably trying to tell you what.
