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

Terminal Server Sessions Disabled

I ran into a couple of issues recently where I was no longer able to RDP onto a server. Whenever I tried to login I received an error "Terminal Server Sessions Disabled: Remote logins are currently disabled".

To fix this I opened up regedit, connected to the server in question by using the "Connect Network Registry" option (under "File" in regedit) and browsed to the following key;

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\WinStationsDisabled

This was set to 1. I changed this to 0 and was able to login again.
