Maybe I’m dense, but I can’t seem to get network shares, wired or wireless to work consistently in Leopard.  When I was using Tiger everything just worked.  I could connect to network-attached storage, shared folders on other PCs (Windows, Mac or Linux) shared printers, everything.  Leopard is a different animal though.  Pardon the pun.  Sometimes, I double-click on a network share in Finder and I’m connected like normal.  Sometimes though, the shared device doesn’t even show up.  Other times, I can connect, use the share but then it inexplicably disappears.  Every now and then I have to use the Go: Connect to server… menu to manually connect to a share.  Every Windows PC on my network seems fat, dumb and happy.  Vista and XP can see and use everything.  My neighbor still runs Tiger on his Macbook, and it works perfectly on his network and mine.  I’m not completely clueless when it comes to networking, I’m a MCSE, but there is obviously something going on behind the scenes in Leopard that I haven’t figured out yet.  Am I alone?  What about all this “Out of the box useability” Apple braggs about?
