I cannot seem to be able to run adprep /domainprep on my domain\ncontroller... it is the GC and forest root and I want to upgrade to server\n2003. We must have already ran both of these in the past to get exchange\n2003 installed so I am not sure what has changed...\n\nHere is the error I am getting in the adprep log:\n\n<snip>\n\nAdprep verified the state of operation\ncn=446f24ea-cfd5-4c52-8346-96e170bcb912,cn=Operations,cn=DomainUpdates,cn=System,DC=Sidney,DC=nii.\n\n[Status/Consequence]\n\nThe operation has not run or is not currently running. It will be run next.\n\nAdprep was unable to complete because the call back function (null) failed.\n\n[Status/Consequence]\nError message: Windows cannot determine the local sysvol location.
