SYMPTOMS

When you operate a Windows 2000-based mixed domain that contains backup domain controllers (BDCs) that are running Microsoft Windows NT version 3.51 or 4.0, unnecessary replication traffic may be directed at the down-level domain controllers. Note that the amount and frequency of traffic depends on the Group Policy refresh interval. Also, you may receive events that are similar to the following event in the Security Event log on the Windows 2000-based domain controller:

ID: 643 Domain Policy Changed:
Password Policy modified
Caller User Name: PDCname$
