Hi Calguy, welcome to Discussions and congrads on the Imac. If you go into System Preferences => Sharing => Services... may sure Windows Sharing is checked and Printer Sharing if you are going to share a printer. I also have Personal File Sharing checked, but not sure if it is needed for Windows Sharing. Give that a try and post back the results, Bob :~))
P.S. There is a wealth of info here that one of our posters has set up for Windows/Apple sharing, (thanks ifelix)
