[Samba] win xp home media edition / Samba 3.023c

[J]

I have an issue where one client machine (out of 10, the only one 
running 'xp home media') is being forced off periodically and closing 
XP's file browser.  It seems to be random.  My Samba configuration is a 
simple one -- just sharing files, it is not handling authentication.  
All other clients work as expected: Log in, for the first time, access 
as many times as desired after the log in, until you log off.  Are there 
any known issues with 3.23c... and xp home media?

thanks!   --J
