arcgispro 2.0 sql servers
Hi everyone,
I'm trying to connect to a SQL Server 2016 from ArcGIS PRO 2.0.1 and I'm fancing this ERROR: Failed to connect to the specified DBMS instance. After fill in all the parameters I am able to see the database list but when I click OK it turnes into this message:

Specifications:
- Microsoft SQL Server 2016 (SP1) - 13.0.4001.0 (X64) Copyright (c) Microsoft Corporation Developer Edition (64-bit) on Windows Server 2016 Standard 6.3 <X64>
- ArcGIS Pro 2.0.1 running on a Windows Server 2012 R2 Standard
Note:
- SQL Server is installed on a different machine
Can anyone help me with this issue?
Thank you
Roxana
