I've got Vista installed on my home PC (business edition at the moment, although we have ultimate available now). It's set up as a workgroup PC as it's just a PC. My laptop is part of the school domain.
When my PC had XP on it, I could share folders (eg c:\backup) and access them from my laptop - great.
When I upgraded to VISTA, the print shares still worked, but the file shares didn't. Password protected sharing is off but I get from my laptop: "\\paulvista\backup" is not accessible. You might not have permission to use this network resource. Contact .........."
If I turn on password protected sharing on the Vista machine, I get prompted on my laptop for the username and password on the vista machine, which I put in, but then get "\\paulvista" is not accessible. You might not have permission to use this network resource. Contact .........."
What I have managed to do is share the public folder and can therefore transfer files that way. I can also share folders from my laptop to the VISTA machine, but I'm not keen on that because they may be visible at school too.
It's got to have something to do with workgroups and domains, but I can't work out what or why. Anybody had similar experiences?
