my network did exactly this when i set it up. try this: Put passwords on both machines, and make sure both machines are on the same workgroup. if that doesent help try turning on guest account oin both machines. (you might not notice the effect for a good 5 - 10 minutes or so, it will seem like nothing changed, try reboot or delete the network connection and remake it if that happens, or just be patient) and yeah, Kerio is kick a**, AND FREE! ^_^ **tip for kerio: once you have all the permissions set for most of the software you use, export the rules to a floppy disc or another drive, then if you format you can just import the backup permissions and not have to go through all that ticking boxes and allowing or denying everything again
