2014 with error message 40

I have the SQL server 2014 version and I keep coming up with an error message 40. "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) The system cannot find the file specified."
The TCP for Express and SQLServer are also enabled. The Browser is Running but the Express is not. That also gives me an error message. I can not change my settings for Firewall, due to my job's security.

Can someone please!!!!! HELP ME!!
