Windows 10 had some recent updates that may cause problems with networked legacy applications. This might be the problem you are running into. Here is a solution:

  1. Open regedit.exe
    Open regedit.exe by simply typing in regedit into the start menu search bar and press enter.
  2. Navigate to System
    Using the navigation pane, go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem.  There should be several DWORDS already in there.
  3. Add DWORD EnableLinkedConnections
    Right click on the white space on the right pane, and select New>DWORD (32 Bit) Value. Name the DWORD EnableLinkedConnections. Lastly, change the value of the DWORD to 1
  4. Restart Your PC
    You’ll need to restart in order for the change to take effect. This should solve the problem.
