I have a Vista SP1 32 bit machine. The machine has a network share that contains volume mount points to the volumes of the vista machine ( created using the SetVolumeMountPoint API ). When browsing the network share from another computer ( either Win7 64 bit, Win7 32 bit or Vista SP1 32 bit ) using Windows explorer the following problem occurs: 1. First, both volume mount points called "c", "d" appear fine. 2. I browse into directory "c" and see all its contents properly. 3. I go back to the root of the shared folder and now I only see "d". "c" has disappeared from the directory listing 4. I enter "d", see all its contents, go back to the root of the shared folder and now it's empty. "d" disappeared as well. 5. If I manually go to \\<path to shared folder>\c from the address bar - then all is fine and I can browse its contents. ( same with "d" ) The same issue does NOT occur when creating a similar share with volume mount points on Windows XP SP2 or SP3. This issue seems identical to the following thread I've found ( it seems that the thread was posted in the wrond forum and got abandoned ): http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/19a3c862-180a-472c-bd18-73dbee0e9668 Hope I've posted it in the right forum :) Thanks in advance, Barakando
