I have inherited another SQL database (Version 15.0.4083.2) and have noted some problems with the SQL Agent. Specifically the Agent is not logging any jobs (as I just discovered trying to check logs to debug an issue). I am seeing the following errors in the agent logs:
[298] SQLServer Error: 53, Named Pipes Provider: Could not open a connection to SQL Server [53]. [SQLSTATE 08001]
[165] ODBC Error: 0, Login timeout expired [SQLSTATE HYT00]
[298] SQLServer Error: 53, A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online. [SQLSTATE 08001]
[382] Logon to server 'NotMyClient' failed (ConnLogJobHistory)
(Server name substituted)
This is saying to me that the agent is trying to attach to an incorrect servername/instance. I have then checked the agent properties, i.e. right click on agent, and under Connection it also lists 'NotMyClient'
However when I click on View connection properties the correct IP and computer name.
I have looked at several options for correcting this, but the majoity of answers seem to basically consist of wiping the database, not an option in this case. Also seen a suggestion that the instance name is incorrect, but can see no way of changing the instance name on the server agent.
Any suggestions are greatly appreciated.

Unable to Connect to Server in Microsoft SSMS
Getting the below error! Please refer to the attachment for more details.

The network path was not found
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.
complete Crystal Reports noob here.
I am having trouble runing a Crystal report since I changed database servers. essentially I set up the exact opy of our database including users and passwords with only the IP changing. When I change the IP in the report connection I get the following:
Logon failed. Details: ADO Error Code: 0x Source: Microsoft OLE DB
Provider for SQL Server Description: [DBNETLIB][ConnectionOpen
(Connect()).]SQL Server does not exist or access denied. SQL State:

Unable to connect: incorrect log on parameters.
I have already opened and checked the firewall on the SQL server to make sure it is open and have used a rule we use for other websites to connect. I have also checked the firewall log for any rejections but this is completely empty.
I have checked the SQL server is running for both named pipes and TCP/IP (and default port).
Has anyopne any ideas why this connection is not working?
Thanks for you time. All suggestions greatly appreciated.

When i am trying to connect to the Azure DB from SQL Management studio an getting teh below error. Not sure why am getting this error as i was able to acess the DB erlier from SQL Management Studio.
Need help on this.

I think probably you haven't configure any Azure DB firewall rules to allow your computer's IP to communicate with your Azure DBs.
Simple things to check (not sure what you've tried so humour me here):
You're connected to the outside network.
Instance\Database name, username and password are correct.
Instance and database are online and connectable (Azure servers not down for scheduled maintenance or run out of paid services.)
Firewall rules are incorrect.
Also I think this question here is identical to your question. Try checking that out.
I tried to login to a remote server and I saw the error given at the link -
http://www.microsoft.com/products/ee/transform.aspx?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=2
Message says -
Message: An error has occurred while establishing a connection to the server. When connecting to SQL Server, 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) (.Net SqlClient Data Provider)
Which is followed by -
Explanation
SQL Server did not respond to the client request because the server is probably not started.
Arent the message and explanation contradicting each other ? Which one is the correct reason for the problem ? How do i find out the REAL source of the problem ?
They don't contradict each other. They just give different possible reasons:
SQL Server doesn't allow remote connections
SQL Server is not started
To fix it, make sure that SQL Server allows remote connections and is started.
Allowing remote connections can be done in the "SQL Server Configuration Manager":
Start that program on the server on which SQL server is installed.
Navigate to "SQL Server Network Configuration" -> "Protocols for "
Double click on the connection type - e.g. Named Pipes - and set "Enabled" to "Yes".
If you are enabling TCP/IP, make sure to also enable each individual IP address on the second tab.
See this blog post for more info.
Thee program you are using is unable to find SQL server on the port/address it expects to.
This is likely either because it is misconfigured, or because SQL server is stopped.
I suggest you open a desktop login to the machine in question, and see if SQL server is running.
There are other potential causes for this problem, as well: network problems, for example.
SQL Server Management Studio is not connecting on my database server machine at production server.
Whereas production sites accessing database. When I tried to connect database from SSMS, I get this error:
Cannot connect to 111.11.11.11.
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

(Microsoft SQL Server, Error: 53)
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:
HResult 0x35, Level 16, State 1
Named Pipes Provider: Could not open a connection to SQL Server [53].
Sqlcmd: Error: Microsoft SQL Server Native Client 10.0 : A network-related or instance-specific error has occurred while establishing a connection to SQL Server.
Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online..
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.
