Microsoft has confirmed that this is a problem in the Microsoft Active Directory Connector. This problem was first corrected in Microsoft Exchange 2000 Server Service Pack 1.
NOTE:: Executing Update.exe to upgrade Exchange to the next service pack does not upgrade the ADC.EXE component. To upgrade the ADC.EXE component to your current service pack level, locate the ADC directory in your service pack CD or your expanded downloaded package, run setup.exe within that directory, and choose the reinstall option. The updated ADC component can be installed before installing Exchange or upgrading to a service pack.
