SYMPTOMS
When you perform an in-place upgrade of Microsoft Small Business Server (SBS) 2000 to Microsoft Windows SBS 2003, you may receive the following compatibility error message:
Setup has detected that the Active Directory forest and domain need to be prepared for Windows Server 2003.
This error message appears in the
Report System Compatibility dialog box during the Preparing installation phase of the in-place upgrade.
If you click
Details, the
Compatibility Details dialog box describes how to run the
adprep /forestprep command and the
adprep /domainprep command.
However, when you run the
adprep /domainprep command, you may receive an error message that is similar to the following error message:
Adprep was unable to complete because the call back function (null) failed.
[Status/Consequence]
Error message: Windows cannot determine the local sysvol location.
Upgrade of Domain Group Policy Objects failed. (The system cannot find the file specified.)
[User Action]
Check the log file Adprep.log, in the C:\WINNT\system32\debug\adprep\logs\log number directory for more information.
Adprep was unable to update domain-wide information.
[Status/Consequence]
Adprep requires access to existing domain-wide information from the infrastructure master in order to complete this operation.
[User Action]
Check the log file, Adprep.log, in the C:\WINNT\system32\debug\adprep\logs\log number directory for more information
When you open the Adprep.log file, it contains this same error message with no additional details. Therefore, you cannot continue the in-place upgrade.
Note You may experience the previous symptoms after you follow these steps during an in-place upgrade of SBS 2000:
- You manually run the adprep /forestprep command after you are prompted to run adprep.
- You manually run the adprep /domainprep command after the adprep /forestprep command is completed.
