Error when you run the Best Practices Analyzer tool on a computer that is set to the Japanese system locale in Windows Server 2012

S’applique à : Windows Server 2012 DatacenterWindows Server 2012 DatacenterWindows Server 2012 Essentials


Consider the following scenario:
  • You have a computer that is running Windows Server 2012.
  • The system locale setting of the computer is set to Japanese.
  • You install the Network Policy and Access Services (NPAS) server role with default settings on the computer.
  • You try to run the Best Practices Analyzer tool to scan Network Access Protection (NAP) components.
In this scenario, the scan fails. Additionally, you receive an error message that resembles the following:
Cannot convert value "System.Object[]" to type "System.Xml.XmlDocument". Error: "'<', hexadecimal value 0x3C, is an invalid attribute character. Line 21, position 8."

  • This issue also occurs when the system locale is set to a language that uses Unicode characters.
  • When you install the NPAS server role by using default settings in Windows Server 2012, only the Network Policy Server role service is installed.


This issue occurs because UTF-8 encoding is not specified during the reading process of the XML files that are related to the Best Practices Analyzer scan.
