Some screen shots of what happens when I select the windows computer from the "Network". I don't have any password on the windows PC. No matter what auth credentials I enter, I always get the same result... no access.
BTW. When attempting access to Ubuntu boxes from windows, windows prompts me for auth credentials and I enter them for my ubuntu box but it doesn't allow access. I can see the ubuntu box listed in "My Network Places" under "View Workgroup Computers" however.
