I'm using the same username/password on all three machines and am a member of the administrators group on all three. One machine is running Windows XP Pro SP2. It has a shared folder with read/write permissions for everyone. I use this folder to get files to/from this computer over my network. I have two additional machines both running Vista Ultimate Final RTM. (Legal from Technet) Both Vista machines can read/execute files from the XP's shared folder. For example, I can open a Word doc, pdf, etc. or install software by launching the exe file directly off the shared folder. They can also copy a file TO the XP's shared folder, edit, or delete. The problem is with simply copying a file that shared folder on the XP machine to the Vista machine while sitting at the Vista computer. I get an error message titled "Destination Folder Access Denied" that reads "You need permission to perform this action". It doesn't matter where I copy the file to. Desktop, Public, Documents, etc. Same thing. So I can open/execute it, but I can't copy it. This happens on both Vista machines. I have enabled the Public folder on both Vistas and they can copy files to/from each other. And the XP machine can copy to/from the Vistas' Public folders. I haven't been able to find much on Google but I have tried disabling UAC and firewalls without and affect. I also disabled Protected Mode in IE7. I know its probably some new security feature designed for retards but damn if I can't find the setting.
