When using a DFS Share, Explorer sometimes requires a manual refresh when new files are created within the share.
Workaround: Create DWord value "NoSimpleNetIDList" = 1 in:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
.REG File
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] "NoDriveTypeAutoRun"=dword:00000091 "DisablePersonalDirChange"=dword:00000001 "NoSimpleNetIDList"=dword:00000001
