某客户：你们的监控软件连接不上我们的后台数据库了，报超时了，请问超时时间怎样设置的？
某人：你们用的是那个数据库的？
某客户：
Exception message: Could not create connection; - nested throwable: (com.microsoft.sqlserver.jdbc.SQLServerException:
The TCP/IP connection to the host XXXX, port 1433 has failed.
Error: "connect timed out. Verify the connection properties, check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port,
and that no firewall is blocking TCP connections to the port.".);
- nested throwable: (org.jboss.resource.JBossResourceException: Could not create connection;
- nested throwable: (com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host XXXX, port 1433 has failed. Error: "connect timed out.

某人：这是mssql server 数据库的。
某人看了一下报错，发现是连接根本创建不了，不别提超时了。
某人：你们是不是做了什么更改了？
某客户：是啊，我们对数据库做了一些调整，然后就出现这问题了。
某人：好像是TCP/IP请求给阻挡住了，你要查一下是不是 TCP/IP协议给禁止了。点击“SQL Server Configuration Manager" -> "SQL Server XXX Network Configuration -> Protocols for MSSQL SERVER -> TCP/IP，如果是被禁止了，就启动一下。
某客户：好的，我们试一下。
