The latest Vista upgrades were applied2. I upgraded Kaspersky Internet Security to version 8For a time I was able to establish connections after rebooting; that is no longer the case.Any suggestions?

Hello Jack CR2, Kaspersky Internet Security includes a built-in personal firewall program. If you haven't already, make sure it is properly configured for the local area network. An improperly configured firewall can block file and printer sharing. If you continue to have problems, thentemporarily disable or uninstall Kaspersky and check the result. Let us know how it goes. -- Eric Cross Microsoft MVP (Windows Desktop Experience) http://mvp.support.microsoft.com
