How to check SAMBA locally, and remotely

[GCMartin]

I've got 2 PCs with different hostnames on a LAN running Linux-SAMBA 3.5.5 that have exactly the same smb.conf as follows:

[global]
	workgroup = STUDY-Group
	server string = Samba Server
	security = SHARE
	log level = 5
	log file = /var/log/samba/log.%m
	max log size = 50
	dns proxy = No
	guest ok = Yes
	hosts allow = 127.0.0.1, 192.168.1.0/24
	hosts deny = 0.0.0.0/0
	case sensitive = No

[homes]
	comment = Home Directories
	valid users = %S
	read only = No
	browseable = No

[printers]
	comment = All Printers
	path = /tmp
	create mask = 0700
	guest only = Yes
	printable = Yes
	use client driver = Yes
	browseable = No

[Downloads]
	path = /mnt/sda10/Downloads
	read only = No

1. For outgoing shares
What command can I enter on each machine to see what is being shared out to my LAN?
2. For incoming shares
What command should I use to see what others are sharing for me to use?
3. Windows PC
On a Windows machine in the network, will I see an icon somewhere for the 'HOME' share for my ID after I authenticate? Or will it be a drive-letter?

thanks in advance
