I'm trying to get started in a test network of three servers (Exchange 5.5, a PDC/GC, and a Windows 2003 server that'll run exchange 2003) that duplicates our working environment. But the deployment tools DSCONFIGSUM, EXDEPLOY, and GCVERCHECK give me this message: "Warning: Either you do not have permission to view hidden objects in the Exchange 5.5 directory, or the directory is not Exchangew 5.5 SP1 or later." I have rerun the SP3 update on the Exchange 5.5 server; spent a day whittling everything unusual out of Public Folders. Later, I gradually added the Exchange account id to every permission group in AD, and explicitly added the Exchange account to every ORG | Site| Configuration parameter on the 5.5 server trying to get past the error. Exchange 2003 hasn't been out long enough for a discussion of the message to appear throughout the Internet. Does anyone recognise this problem?
