Micro Focus Client for Open Enterprise Server 2 SP4 (IR7a)
Microsoft Windows 10 build 1709 (RS3)


Various symptoms may be observed after upgrading to Windows 10 build 1709 (RedStone 3 / RS3).  The most obvious evidence that you are experiencing the problem resolved by this TID is that when you view the "Provider Order" under "Network Connections" (see TID 7000693), an error message "Failed to get network providers" appears and the network provider list is not displayed.

Other symptoms include:
  • slow login
  • slow opening of folders in Windows Explorer
  • slow opening of files from Microsoft Office


Manually add and entry for NCFSD as DWORD_32 entry with appropriate data under [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\ProviderOrder]

Follow these steps:
