Invisible Folders (Retry).. 8(..

[lpeg at mbasystems.com.ar]

Hi! 
I mounted in my workstation's tree a shared folder that belongs to 
an NT Server. 
When I create a new folder in the server from my workstation I can't 
see it through the "ls" command until about 1 minute after, even 
though I can change to the directory and copy files to it.

Does anybody have any idea about what's happening? 
Thanks 
PD: I've got Samba 2.0.7 and the NT Server has SP4 installed
