Symptoms
When you use the Microsoft SharePoint Migration Tool (Smigrate.exe) to try to restore aMicrosoft Windows SharePoint Services 2.0 Web site, the restore operation fails. You also receive the following error message:

Error getting manifest for http://localhost (fatal)Progress: An error occurred accessing your Windows SharePoint Services site files.This issue occurs after you use Smigrate.exeto back up a Windows SharePoint Services 2.0 Web site.
Additionally, when you rename the Backup.fwp file to Backup.cab to view the contents of the backup file, the Manifest.xml file is 0 bytes.
Resolution
This problem typically occurs on Windows SharePoint Server 2.0 Web sites if one of the following conditions is true:The Web sitecontains many lists.The Web site containslists that have large items.The Web site backup contains many files.Note Only file metadata is stored in the Manifest.xml file. The files are exported separately.
During the backup process, two contiguous memory blocks are required to create the Manifest.xml file. The memory blocks must be large enough to accommodate the manifest data. If one sufficient memory block is available to create the Manifest.xml file but a second sufficient block is unavailable, the copy operation fails silently. Then, a Manifest.xml file that is 0 bytes is created.
