I am using SQL server 2017 and SSMS 14.
I have read the topic in

enable TCP/ip from SQL Server configuration Manager.
try different internet providers.
Upgrade SQL server to 2017.18.1
Make sure all services are enabled and running.
Restart services and the machine.
Create azure SQL DB to use name instead of IP.
turn off firewall.

I have reinstalled my SQL Server 2016 as for an unknown reason which lead to the SQL Server down...But, when I finished the installation, I found I can not connect to (LocalDB)\MSSQLLocalDB any more. I got this error message from SQL Server.
Cannot connect to (LocalDB)\MSSQLLocalDB.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

(provider: SQL Network Interfaces, error: 52 - Unable to locate a Local Database Runtime installation. Verify that SQL Server Express is properly installed and that the Local Database Runtime feature is enabled.) (Microsoft SQL Server, Error: 2)
Anyone who have any ideas of how to solve this problem? I do need to speed up for my development, but the DB issue stops me to do anything.
LocalDB is a special version of SQL Server Express - if you haven't installed it, you cannot use that server/instance name to connect to it.
You can easily install SQL Server Express LocalDB separately, side-by-side with SQL Server Developer edition - but you need to install it explicitly.
See this other SO question on the topic for more details
i have a windows server 2008 set up as a database server, i used to have MS SQL 2005 installed on it, due to some client changes i installed SQL 2008 R2 along with the 2005, the R2 is with a named instance. when i tried to connect an application to the 2008 R2 database, i get:
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: TCP
Provider, error: 0 - A connection attempt failed because the connected
party did not properly respond after a period of time, or established
connection failed because connected host has failed to respond.)
i am sure of the ports as i checked the named instance configuration on the DB server, i also telnet the dynamic IP from the application server and it is going through. i also tried to connect a copy of the application from a demo server i have with the same configuration as the application server and it was successful. from the application server it is not, any suggestions?

I've just installed SQL Server 2005 Express and I'm trying to login to Management Studio but I don't know what the "Server Name" is to be able to login.
I've tried:
localhost\SQLEXPRESS
127.0.0.1\SQLEXPRESS
SQLEXPRESS
<computer name>\SQLEXPRESS
<username>\SQLEXPRESS
The authentication mode is Windows Authentication.
The error message I'm getting is:
Could not connect to <computer name>\SQLEXPRESS.

Does anyone point me in the right direction?
Is the SQL Server Express service even up and running??
The local machine can be defined as . or (local) for SQL Server, and the SQL Server Express instance name is SQLExpress by default.
So .\SQLExpress or (local)\SQLExpress ought to work.
If they don't, maybe the service isn't up and running??
I am new to managing servers but I have just been given full access to set up an MS SQL Database on win server 2003. I have created a Database successfully and can connect locally (via remote desktop server)
Problem is I can't connect to the database from my personal computer (remotely, via ms sql server management studio). I have followed several tutorials such as: http://blog.sqlauthority.com/2009/05/21/sql-server-fix-error-provider-named-pipes-provider-error-40-could-not-open-a-connection-to-sql-server-microsoft-sql-server-error/
The error I am receiving is:
Cannot connect to 'servername'
ADDITIONAL INFORMATION:

Any help will be great, thanks!
"SQL Server is configured to allow remote connections"
You need to enable remote tcp/ip connections in sql surface area configuration. It's new in 2005 and then dropped in 2008.
If that doesn't work, you either have a network issue are are perhaps giving the wrong name - maybe you installed a named instance?
