Client w/ W2K Exchange 2000 server -- DC with SP3. The application event log is full of warnings about MSExchangeIS, event ID 9543 with error messages such as: Unable to create Public Folder proxy object for "all public folders" in Active Directory. When Iook in ADUC, I note that under the Exchange System Objects folder, there are no objects here like there should be. This install was done w/ the Administrator account which is in the schema group and have done this b/4 w/ no problems... The users are experiencing no problems... just the issues w/ the Event Log. Any suggestions on how to clean this up? Thanks in advance. Lee Swanson
