How to fix Named Pipes Provider, error: 40 - Could not open a connection to SQL Server? - sql-server-2014

I'm having trouble connecting or logging in to my SQL Server database. I had a previous working instance before, but I forgot the password and decided to just reinstall the whole thing since I don't have any data to lose. I realized that was a bad idea but now, each time I attempt to log in to my SQL Server, I get the following error message:
I tried to search for an answer, but it seems nothing is working. Here is what I tried so far:
Enabling the Named Pipes from the SQL Server Configuration Manager under the SQL Server Network Configuration tree item
I tried restarting the SQL Server item from the list of services in the Services application
I tried restarting everything in the SQL Server Configuration Manager that is related to my database or at least have my instance's name on it
There are other things that I tried which I fail to remember. Any help would be much appreciated.

FireDAC Lost connection to MySQL server during query

I have two FireDAC connections on my application, one is intended to be used on a MySQL Server that is on LAN and store private data of the my shop (like sales, products, etc), and the another one is connected to a remote (internet) MySQL Server, and it randomly give me a exception
First chance exception at $745AA882. Exception class
EMySQLNativeException with message '[FireDAC][Phys][MySQL] Lost
connection to MySQL server during query'.
Is this a issue on FireDAC, my code or the remote MySQL Server?
Using NAVICAT software I have no problem.
This error usually occurs because the Internet Connectivity is not stable and connection closed during exchanging data
Sometimes you can solve this issue with increasing the connection Time-Out (and ReadTimeOut )
Sometimes this error occurs because you are trying to send or receive large amount of data like Blob fields and you should increase the max_allowed_packet variable of MySQL Server to solve the problem
The next suggestion for solving this problem is avoiding dns lookup by adding skip-name-resolve to the settings of your MySQL Server
The Main reasons of this problem is connection stability and MySQL Server Settings

Unable to connect to any of the specified MySQL hosts in NHibernate, MySql

One of the client is reporting this issue happening in our application. NHibernate throws Unable to connect to any of the specified MySQL hosts in the middle of the app running, so it is not a mistake in the configuration. It happens randomly, but always when the transaction is opened.
I saw this:
NHibernate, MySQL, Windows Server 2003 -- connection problems
But the server in my case is Windows 2008. And app opens only single connection simultaneously. MySQL version is 5.5.28. Server is on the remove machine
Unfortunately the app requires the HW I do not have, and I cannot reproduce it locally.
Any ideas or directions I need to dig in?
Try connecting using the full directory name, e.g. instead of Server=SRV use
Server=SRV.yournetwork.com
It might be that is has trouble resolving the server name.

Trying to create a new linked server in SSMS: Can't find table 0

All of my Linked Servers stopped working and I have no idea why.\
When I try to create a new linked server in SSMS I get the following error:
Can't find table
Suggestions?
I'm on 2008 R2.
Update: I was able to connect to SQL, or least it looks liked I was connected in the Object Explorer, but when I try to open a Query Window:
Login failed. The login is from an untrusted domain and cannot be used
with Windows authentication. (Microsoft SQL Server, Error: 18452)
I seem to have no problem signing onto the domain when rebooting my PC..
Bizarre. Rebooting didn't help, but restating the SQL ServerService seemed to corerct the issue.
Update:
Now I am getting
OLE DB provider "SQLNCLI10" for linked server "servername" returned message "Not enough storage is available to complete this operation.".
Final Update:
Total corruption, error message after error message within SSMS whenever I touch teh Link Server functionality.
Solution: Delete ALL the linked servers and re add. This stabalized everything.
Update:
Something about hitting a DB2 linked serevr that just trashes my whole SQL environment.It happened when I recreated the DB2 linked server.

Can't connect to database

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.

SQL Server Error 223 When Connecting

I recently changed SQL Server 2008 from windows authentication mode, to mixed. I created a new user 'taraw' and set a password. I'm connecting to localhost - which works perfect when using windows authentication, however if I want to use SQL Server authentication with my user - taraw, I get the following error:
Shared Memory Provider, error: 0 - No
process is on the other end of the
pipe (Microsoft SQL Server, Error 233)pipe (Microsoft SQL Server, Error 233)
I know the password is correct as I've just created it, I've also tried creating different users, to which I get the same result. I've read somewhere that Namespipes might be disabled? But I haven't found out where or even how to enable this. (EDIT: I have since found this, and it is enabled)
If anyone has any advice it would be MUCH appreciated.
Thanks
I have since solved this problem. I was previously restarting the server within SQL SERVER MANAGEMENT STUDIO, this was incorrect.
I simply restarted the SQL Server within SQL Server Configuration Manager and it worked.
