this is the same problem right: navigating to my shares using UNC path, the destination displays fine, but when you click down into child directories the files may appear momentarily, then dissapear. I found that backing up then back into the directory the files then show. I have had the same problem since installing XPSP2 on my network, not that I think this is the problem. My shares haven't changed in some time, one is 3+ years old so there's definately no permissions problems that caused any problems pre SP2. Shares are on W98 & XPSP1, and i'm sure with other SP2 PC's. Then I also notice the same problem on my home network, again - working flawlessly pre SP2. I have found that without manually specifying the DNS server address the machines refuse to connect at all. If you successfully connect using IP - does that make every subfolder behave as well? I hope this is the same problem because i'd love to fix it. [unable to check right now]. Cheers [edit] Oh yeah - there is a limit to the number of connections to a share in a desktop O/S - and not with server O/S's [such is my limited understanding]. Into my XP box it refuses to connect after about 10 simultaneous connections. [must move the share to a server ]
