Suspected skeleton key attack (encryption downgrade) RC4 error in ADFS Servers

Hi,

I am getting "Suspected skeleton key attack (encryption downgrade) RC4 error in ADFS Servers". when I executed "AoratoSkeletonScan" script I see "checked 0 DCs out of 41 in domain xxxxxxxxxxx. None of the checked DCs were found infected" .

still do I need to do something on our ADFS servers or can we fix this from ADFS servers.
