If you upgrade Windows NT 4.0 to Windows Server 2003, any legacy FTDisk (fault-tolerant disk) sets shares will no longer be shared.
This behavior occurs because Windows NT 4.0 FTDisk sets are not fully supported by Windows Server 2003.
NOTE: You can use the Ftonline tool, from the Windows Support tools, to gain access to your data. See Fault-Tolerant RAID Volumes or Volume Sets Displayed as 'Failed'.
After you use Ftonline, you can make the shares temporarily available:
1. Open a CMD prompt.
2. Type the following commands, pressing Enter after each:
net stop browser
net stop server
net start server
net start browser
net start dfs</b>
NOTE: The recovered shares will only be available during this boot. Rebooting will loose the shares.
You should backup the data, delete the data, and recreate the data as Dynamic Volumes.
