TN PT125 Wonderware unable to view mapped drives on modern operating systems

Details

Below is the fix:

 

  1. Open regedit
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
  3. Right click the system folder in the left pane
  4. Add New -> DWORD
  5. Name the new DWORD EnableLinkedConnections in the right pane
  6. Double click the new EnabledLinkedConnections property, and give it a value of 1
  7. Close out of regedit and restart the machine

 

The above fix also affects programs in addition to Wonderware, where the directory browsing dialog box built into applications don’t recognize mapped drives or properly acknowledges compatible network locations.
