Group Policy Preferences incorrectly sets a network printer as default in Windows 7 and Windows Server 2008 R2

Applies to: Windows 7 EnterpriseWindows 7 ProfessionalWindows 7 Ultimate


Consider the following scenario:
  • You use Group Policy Preferences to deploy a network printer to client computers in a Windows 7 and Windows Server 2008 R2 environment.
  • On one of the network printers, you enable the following options:
    • Set this printer as default printer
    • Only if a local printer is not present
  • On a client computer, you have a local printer installed that does not use a COM, LPT, or USB port. For example, the local printer uses HP DOT4.
In this scenario, Group Policy Preferences incorrectly sets its mapped network printer as the default printer. The expected behavior is that the original default printer setting on the client computer is not changed because the client computer has a local DOT4 printer.


This problem is caused by the printer detection code. This code examines only the LPT, COM and USB ports.
