	Huh?  I have no clue what this is.  Is this a distribution package
or something?  What distribution are you running, vendor and version.

	I'm presuming that the above is something like a RedHat RPM
package name, but I have no idea what's in it.  It's not in any distro
that I've got on line.

	You say "sometimes".  Can you be a little more specific?  Is it
sometimes based on the connection or sometimes based on time.  In other
words, for a given connecton/drive/listing/share does it always work
the same way?  If you do the same listing over and over and over again,
does it always give the double listing or not give the double listing or
does it sometimes do one and sometimes do another.  Is the problem specific
to a particular share or resource?  Do you have this problem with any other
shares or resources other than the 4.0 SP5 server?

	From the listing, I don't see the usual problem associated with
this but...  Is the WIN95 bug workaround compiled into your kernel?  On
most NT shares, it causes radically screwed up file timestamps (byte
ordering is screwed) and that's not present here.  That workaround also
subtly affects packet timing to avoid some Windows 95 problems.  It should
always be disabled unless you only have Windows 95 for servers.

	Service pack 5 is relatively new so this may be a new phenomina
that may or may not be related.

	Actually, that's fine by me.  I'll take a look at it.
