Our small office network has a number of true networked printers, but also some which are Windows shared printers. We've always set these up on a local port using the UNC path to the printer as the port name. This enables us to re-name the printers as required; it also seems to be the only way the document spooler on our ERP software can use them.
This always worked fine when our office PCs were running Windows XP. However we've just completed upgrading / replacing them with Windows 7 in readiness for the end of XP support. When I try to install one of these printers on a W7 machine using the UNC path I get an 'Access Is Denied' error message.
I have file and printer sharing enabled, password protected sharing switched off, and full permissions granted to 'Everyone' in the printer security settings. What else do I need to do to get this to work?
