[Samba] 3.0.2a - homes occasionally missing

[Stewart, Eric]

	Clients are Windows 2000; server is running Samba version
3.0.2a.  We're experiencing a sporadic issue with the homes share
occasionally coming up missing.  All other shares remain mappable and
accessable.  If the workstation is rebooted, it can once again access
the share.
	This is new behavior; 2.2.8a did not have this problem.  As of
yet I haven't been able to figure out what circumstances might trigger
the homes share disappearing.
	Relevant sections of my smb.conf are reproduced below.

	I have gone through much documentation (though it wouldn't
surprise me if I missed something) and groups.google.com searches didn't
result in a solution (and only one dead on "I'm having this problem"
match).
