SQL Network Interface error when running DBHelper.exe


Database Helper (DBHelper.exe) is an open source application that assists with programming and interacting with a Microsoft® SQL Server® database. When you run Database Helper on your Patch Manager SQL Server database, the following error displays: 

SQL Network Interfaces, error: 26 - Error Locating Server/Instance specified


Patch Manager 2.1


  • Network issue
  • Incorrect server or name instance
  • Patch Manager server issue


To resolve the networking firewall, and SQL-related causes for this error, see SQL Network Interfaces, error: 26 – Error Locating Server/Instance Specified (© 2018, Microsoft Corporation, available at, obtained on February 28, 2018).

If this procedure does not resolve the issue, repair the Patch Manager installation on your Patch Manager server.

    • SQL Browser service is running

    1. Log in to the Customer Portal
    2. Click Downloads and select Download Product.
