Hi; Have an Exchange 2000 Server on a network w/ 2 W2K Domain Controllers and less than 50 users. Both servers have SP3 and the Exchange server has SP3. No child domains. System Attendant is running under local system account. Users seem to have no problems, but the Application log is putting entries every couples minutes w/ Event ID 9543 w/ source MSExchangeIS. The description is similar to (see below): Have searched MS site and the results do not appear to apply to this situation... Right now there are no additional Public Folders in the Exchange Server. Any insight would be appreciated. Thanks much. Lee Ann Swanson SD, USA Unable to create Public Folder proxy object for folder "img" in the Active Directory.
