Cannot connect to an SQL server using Windows authentication when specifying a machine name

Updated August 9, 2017


When specifying a machine name in your Windows credentials for your SQL server, such as hostname\administrator,  you may receive an error like the following:

Can not connect to the SQL Server. The original error is: Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was - [Pre-Login] initialization = 18066; handshake = 14340;


Any product running on Orion Platform version 2017.3, such as:

  • NPM 12.2
  • NCM 7.7


This generally occurs when your Orion server and SQL server are placed on different subnets and the SQL server hostname cannot be resolved by the Orion server.


You can resolve this issue in multiple ways.

Resolve this locally to the Orion server

You will need to repeat one or both methods on any other Orion servers you create.

Resolve this for multiple Orion servers

Create a DNS record for the SQL server's machine name.
