Accessing Shares: "The account is not authorized to login from this station"

When trying to connect to an admin share (\\Servername\D$) I was seeing the error "The account is not authorized to login from this station"

This is due to an issue with SMB signing policies and can easily be fixed by ensuring the following keys have parameters as below;

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters

enablesecuritysignature = 1
requiresecuritysignature = 0 


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters

enablesecuritysignature = 1
requiresecuritysignature = 0 


In my case, I found that one of the lanmanworkstation keys did not match. After changing this I could access the admin share
