The network adapter name cannot be retrieved by using ifAlias if the network adapter name contains multibyte characters

Applies to: Windows Server 2008 DatacenterWindows Server 2008 EnterpriseWindows Server 2008 Foundation More

Symptoms


Consider the following scenario:
  • You have a network that is running the Simple Network Management Protocol (SNMP).
  • You use a SNMP agent to monitor the network.
  • You send an ifAlias request to return the network adapter name from the network.
In this scenario, the SNMP agent cannot collect the network adapter name from the network by using the ifAlias request.

Cause


This issue occurs when the network adapter name contains multibyte characters. This behavior is by design. The IfAlias request can only use ASCII characters as mandated by RFC 2863. For more information about RFC 2863, visit the following Internet Engineering Task Force webpage:

Workaround


To work around this issue, and obtain the network adapter name, use the following sample Windows Management Instrumentation (WMI) script.
