[Samba] Killing open file by file and not by pid

[track]

Hello,

i'm using samba-2.2.5 joined into a Win2000 domain and using winbindd.
With smbstatus i can see which files are open and which user/pc are using theme but I can only kill by pid (process id that serve the files to a user) rathen then by single file (as in windows server manager).

How can i kill/disconnect by file instead by pid/user ?
Thanks in advance
