Our server was migrated from a physical server to a virtual server and now we can't connect to SQL Server. We keep getting this 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 the SQL Server is configured to allow remote connections. (Provider (TCP Provider, error: 0 - Only one usage of each socket address (protocol/network address/port) is permitted.) (Microsoft SQL Server, error 10048)
I checked and TCPIP is enable and the SQL Server process is running.
I can login to the server but I can't connect to SQL Server either using Windows authentication or database authentication.
What is missing here?
