SYMPTOMS

You have a computer that is running Windows Server 2008 or Windows Vista. After thousands of IP addresses are bound to a network adapter, you encounter one or more of the following issues:
  • CPU usage reaches 100 percent.
  • Windows Management Instrumentation (WMI) cannot connect remotely to the affected computer.
  • Terminal sessions that are connected to the affected computer have poor performance.
Further investigation indicates that these issues occur when an application calls one of the following functions:
  • GetAdaptersAddresses
  • GetAdaptersInfo

CAUSE

This issue occurs because the method that is used to enumerate IP addresses in the GetAdaptersAddresses function and the GetAdaptersInfo function is not optimized. Therefore, lots of IP addresses that are bound to one network adapter cause slow performance issues.
