Here is a suggestion from a users group:
SubInACL in the Win2k Resource kit is able to do this:
subinacl /noverbose /file \serversharedir /setowner=whoever
subinacl /noverbose /subdirectories \serversharedir* /setowner=whoever
If you don’t have the Win2k RK, the SubInACL.exe in the Windows Server 2003 RK
(free) will maybe work on Win2k as well.
Windows Server 2003 Resource Kit Tools
The kit will install on WinXP or later so you can get to Subinacl.exe. See the
Resource Kit help file for more about the system requirements for SubInACL.
