I marked this solved when I discovered, after much reconfiguring, I had a faulty Netgear router - I just thought I'd save you reading all this to find the answer. Cheers
I have 3 machines at home all running Lucid. All have Samba and shared folders but I can't access files on any machine from any other. This worked ok when they were running Karmic. I'm also unable to set up printing across the network from the two machines without local printers. The main machine has 2 printers connected via USB, the others are using WiFi. I'm not using firewalls on any machine.
On any machine I go to Places, Network and Nautilus opens at network:/// and shows me 'Windows Network' I open that and see the Workgroup folder which I open and see the folder is empty. (I did see the 3 machines before I completely removed Samba and re-installed a few minutes ago)
On one of the remote machines I go to Add Printer, Select Device, Network Printer, Windows Printer via Samba, Browse but I can't see the machine with the printers attached in the Workgroup. Another clue is that when I look at the printer properties, policies on the main machine all 3 boxes are ticked, Enabled, Accepting jobs (but it says Not published) and Shared.
Basically guys, the more things I try the worse it gets. Can someone put me right?
