SYMPTOMS
When a Microsoft Windows 2000 client that is connected to a Microsoft Windows NT 4.0 domain tries to populate the USERDNSDOMAIN environment variable by using a call to a DsGetDCName (API) that has the DS_RETURN_DNS_NAME flag and the DS_IP_REQUIRED flag, excessive network traffic may occur. This issue may occur when the Windows 2000 client runs Microsoft Internet Explorer 6 or Microsoft Outlook Express.
CAUSE
This issue occurs because the DsGetDCName API that has the DS_RETURN_DNS_NAME flag and the DS_IP_REQUIRED flag does not apply to Windows NT 4.0.
