Thankyou for your time.

How are your lan connected... ?
Your active connection now seems the wireless connection not the wired connection.

Thank you.

the lan is a mixture between wired and wireless computers. I am connected to a wireless router via wireless, but the computer i am trying to access is attached via cable to the router. I used to be able to navigate the network, and i can still see the network, when i click on network drives but can't get further than seeing the name of the network, no computer show up and the printer cannot be found.

Thank you again

Then please do a network scan... from terminal type:

nmap -sP 192.168.1.0/24

Then to view active services:

If it exist, can you open and paste some content of your /etc/samba/smb.conf file...?

I'm interested to this row: "name resolve order = lmhosts wins bcast host"

Open a Terminal from the menu Applications->Accessories->Terminal and type:

gedit /etc/samba/smb.conf

Please copy only this line...

Thank you

# What naming service and in what order should we use to resolve host names
# to IP addresses
; name resolve order = lmhosts host wins bcast

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
; bind interfaces only = true

Hope this is the right bit! Thanks

You are amazing thank you so much for your time and help works like a charm!
