Hi Matsco, Thanks for the post! Did you enable the UAC on your Windows 7 clients? The issue might happen when access network locations. If so, create a new registry key to check if it works. (Note: Backup the registry before the change in case of any risk.) HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System Type: DWORD Value Name: EnableLinkedConnections Value: 1 If it doesn't work, please also ask this question in Windows Server forum.
