I have SQL server 2008R2 (instance name - SQLServer2008) and SQL server 2012(Instance Name - MSSQLSERVER2012) was installed in my local PC.
I can able to login using SQL 2012.
E.g:
server Name : .\MSSQLSERVER2012
Authentication : SQL server Authentication
User name : sa
password : test123
But same way i tried to login SQL server 2008R2. (I tried to login using Windows Authentication and SQL Server Authentication, But i am not able to login. I am getting bellow error.)
E.g:
server Name : .\SQLServer2008
Authentication : SQL server Authentication
User name : sa
password : test123

I'm trying to connect to a Postgres DB using Oracle SQL Developer. This is the datasource URL I see in an application which uses the DB:
jdbc:postgresql://10.11.12.13:5432/mydb?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory&sslmode=require
I have the correct username and password but when I try to connect I get:
Status : Failure -Test failed: IO Error: got minus one from a read call
I think this is because I don't have a SID or Service name populated. How can I find what these are?
The error:
A connection was successfully established with the server,but then an error occured during the login process(provider:SSL Provider:0-The specified data could not be decrypted.) (Microsoft SQL Server0
Open Connect to Server box and unset Encrypt connection option in Connection Properties tab.
My application server (say 192.168.100.1) and database server (say 192.168.100.2) both are on the same domain. I'm trying to create an ODBC connection from the application server to a SQL Server database on the database server, but at the time of login it generates this error:
Microsoft SQL Server Login
Connection failed:
SQL State: 'HYT00'
SQL Sever Error: 0
[Microsoft][ODBC SQL Server Driver]Login timeout expired
I've checked all configuration for SQL Server and tried possible solutions without resolving this issue.
Important:
A DSN can be successfully created from my own PC but when attempting this server to server as described above, ODBC is facing this problem.
OK, I have got the solution. Sometimes, if SQL Server can't be found on network by its name while creating DSN in windows, the logging in takes time more than usual which tells ODBC manager that Database Server we are looking for is not responding or responding too late.
Solution.
Instead of selecting server from the list while making dsn, use 'server-ip\SQLExpress'.
e.g 192.168.100.2\SQLExpress.
Thats All.
I have an instance of SQL Server 2008 R2 on my local machine, and today, when I try to connect via Management Studio (as I used to do with no errors, using Windows Authentication), I get the 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) (Microsoft SQL Server, Error: 2)
Any sugestions?

I tried both window and SQL Server authentication but no success.
please help.
First Check whether any SQL Server Instance is running and exists.
You can check list of instances as per below:
Go to command prompt and type in “osql -L” or “sqlcmd -L”.
If instance is showing in list then check your credentials.
Start the sqlserver service. Nothing to do in stackoverflow. Move question to serverfault.
