~Ned OpfookonyoniSep 26, 2018, 4:43 PM1 PostsMapped Network Drives are not visibleHere's the solution we are using... Symptoms Mapped network drives are not visible when creating attachments from Lotus Notes on Windows 7, 8, 10 when the User Account Control (UAC) is enabled. Cause This problem occurs because UAC treats members of the Administrators group as standard users. Therefore, network shares that are mapped by logon scripts are shared with the standard user access token instead of with the full administrator access token. Solution Configure the EnableLinkedConnections registry value, which allows Windows to share network connections between the filtered access token and the full administrator access token for a member of the Administrators group. To configure the EnableLinkedConnections registry value, follow these steps: 1. In Registry Editor, locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System 2. Right-click Configuration, click New, and then click DWORD (32-bit) Value. 3. Name the new registry entry as EnableLinkedConnections. 4. Double-click the EnableLinkedConnections registry entry. 5. In the Edit DWORD Value dialog box, type 1 in the Value data field, and then click OK. 6. Exit Registry Editor, and then restart the computer.
