samba - Jan 1999 - Can I make the IPC$ share guest ok?

Hi,

Is it possible to make only the IPC$ guest ok so that you don't have to
have to specify a password?

In other words, I'd like 'map to guest'=bad user for all shares
*except* IPC$, but to allow any user to browse the share list (ie: map to
guest=bad password" for IPC$ only)

Thanks.
