While connecting to SQL Server 2005, I am getting the following error.
"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (Provider: Named Pipes Provider,
error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)"
I restarted the Server and then tried to connect to SQL Server, it is allowing me to connect. Whenever the problem comes, I am restarting the server. But I want the actual solution for this problem.
Can anybody help me out in solving this issue.

I cannot connect to any remote SQL Server instances from my system. I used to connect them from SQL Server Management Studio. Moreover, I can still connect to the same SQL Servers remotely from another systems (my colleagues' system).
I am getting following error:
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)
Error Number: 53
Severity: 20
State: 0
I have checked:
Named pipes/TCP is enabled.
Remote connections are allowed.
Windows Firewall is off.
Enabled everything in SQL Server Configuration Manager.
Also, I have tried everything mentioned in this post-
How do I fix the error 'Named Pipes Provider, error 40 - Could not open a connection to' SQL Server'?
But still could not solve my problem. Please suggest any method which allows me to fix this error and connect to the remote servers again.
instead of check whether that server system is working or not, because sometimes if the server system is not working means we are unable to connect to that system

First of all, your server name regularly is localhost instead of root. Second, from SSMS 16 up, you need additional installation of localhost server. You can read the reference here.
After numerous attempts I tried many versions, I was able to fix this issue by installing the SQL Server 17. I was successfully able to create a server and connect to SQL Server.

I was using this SSMS last couple of years,n this SSMS is running fine since more then year on production database server n i didn't closed ever, now when i connecting this SSMS but facing this issue, whereas my sites which accessing this database is working fine.
I also tried to access database from sqlcmd but no luck n facing facing this error:

I thinks we resolved the issues.
1. Active Directory server was not behaving, so
2. SQL server couldn't run without credentials and
3. they found another SQL server issue and fixed it.
We started looking into the SQL connections that my team had found and it lead us to find that the Active Directory server had basically crashed. It was allowing us to log in however it wasn't able to access the majority of the AD functionality. We ended up rebooting the AD server which corrected the issue however we were still seeing issues with the SQL cluster manager and SQL itself was rejecting connections on a somewhat regular basis.
After the AD server was rebooted we were able to log into the SQL cluster manager but with limited capabilities, since it had been erroring due to the AD issue we restarted the cluster service to see if this would correct the issue. This caused the SQL service to fail over to the passive server and caused SQL to start rejecting even more connections than it had been. The cluster service started working with this restart however the SQL connections were getting worse. We found that the IPv6 protocol was enabled for the SQL service which causes problems, like the ones we were seeing, in SQL clusters, to disable this we had to reboot the 2 SQL servers. We rebooted them one at a time and once they were back up everything was working properly.

Please help!
Thanks!
Your SQL Server doesn't allow for remote connections. Depending if you have access or not,
follow this url http://support.microsoft.com/kb/914277
But, this is pretty insecure, good luck.
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:
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

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?
