Error while adding Replica to SQL Server 2012 AlwaysOn Availability group

Problem: While adding secondary replica to AlwaysOn Availability group you get following error

TITLE: Connect to Server
Cannot connect to REPLICASERVER.
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: 5)
For help, click:

Solution: Most likely Named Pipe provider for SQL is disabled on secondary instance

Open SQL Server Configuration Manager and click on Protocols for MSSQLSERVER under SQL Server Network Configuration

Enable Named Pipes provides

Restart SQL Services

Then try adding the replica again in New AlwaysOn Availability Group Wizard
