samba - Aug 2012 - Fwd: NET RPC CLOSE FILE <fileID> command is not working

Hello All,

After executing NET RPC CLOSE FILE <fileID>  command,the files which we
have opened from windows is not closing.
Instead of using this command we have  used  KILL command to kill all the
process forcefully.

We are using samba-3.5 which is installed on  Unix platform.

Is there any specific version of samba version supporting this command? or

Can  you please help  to resolve this issue.

Thanks in advance,
