I have a friend with a really simple network: Both machines run Vista Home Ultimate, 1 is a laptop and 1 a desktop. They both belong to the same workgroup. The desktop has a printer attached to it which is shared. The desktop has an USB external hard drive which is shared. The laptop can see and print to the printer without problem. The laptop can see but cannot open or save to the ext HDD - error message says 'do not have permission to access....' desktop settings are set to share files and printers without passwords: it does not matter if the public folders are shared or not, and setting the shared properties for the ext HDD to access for everyone and allowing change files makes no difference either. Turning off the firewall makes no difference either Any ideas anyone??
