Running into a problem with logging from Windows 7 to connect to a Windows 2008 SBS Server. This was due to the latest windows update KB4103712 in March 2018.
To fix this problem, you need to create the following registry on the windows 7 desktop
Registry path: HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters
Value: AllowEncryptionOracle (DWORD): 2
