[SOLVED] [W10V1703B15063 x64] Firewall: 'Policy import failed' 'Access is denied' 'code: 5'.

[xilolee]

If you receive this error when importing your own policy in windows firewall with advanced security:

---------------------------
Windows Firewall with Advanced Security (title)
---------------------------
Policy import failed.
Error: Access is denied
Code: 5
---------------------------
OK (button)
---------------------------

Check the Enabled entry in this regedit location: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy].
If it is set to 1, you'll receive the error.
To not have this issue, set it to 0 (zero, nought).
I have these entries, always in that location:

"MDMEnabled"=dword:00000000
"Enabled"=dword:00000001

I don't know who or what modified this entry...
