[Samba] Share not available

[rationalsupport]

Hi 
	i installed and configured SAMA 2.2.8a on HP-UX 11.0

	Everything is working

	The only problem is after certain number of users ( ~ 20 ) connected
to samba,
	Network share become invisible

	Has anyone faced this kid of problems? 
	can u give some leads

	Also do any one knows how to set idle session timeout  for users
	i.e. I want terminate connection from ideal users ,say in 5 minutes


	Thanks
Tom
