Network file sharing has always been buggy in my windows/mac mixed environment, but I managed to live with it. It worked for 85% of the time. However, since upgrading to SL, it now works less than 5%. It keeps telling me "there was an error connecting to the server. please check ip addr, etc.......". It'd work for a few minutes after each restart and then resume its habit of annoying the hell out of me. Is this a common problem with Sl and Win 7? (BTW, win7 to win7 or win7 to vista file sharing works perfectly). Any ideas? Thanks!
