Common scenario is that the client has the CredSSP update installed, and the Encryption Oracle Remediation policy setting does not allow an insecure RDP connection to a server that does not have the CredSSP update installed. On the client has the CredSSP update installed Run gpedit.msc , and then browse to Computer Configuration > Administrative Templates > System > Credentials Delegation in the navigation pane. Change the Encryption Oracle Remediation policy to Enabled , and then change Protection Level to Vulnerable . If you cannot use gpedit.msc, you can make the same change by using the registry, as follows: Open a Command Prompt window as Administrator. Run the following command to add a registry value: REG ADD HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters\ /v AllowEncryptionOracle /t REG_DWORD /d 2

A virtual private network (VPN) provides a means by which remote computers communicate securely across a public WAN such as the Internet. A VPN connection can link two LANs (site-to-site VPN) or a remote dial-up user and a LAN. The traffic that flows between these two points passes through shared resources such as routers, switches, and other network equipment that make up the public WAN. To secure VPN communication while passing through the WAN, the two participants create an IP Security (IPsec) tunnel. Note: The term tunnel does not denote tunnel mode (see Packet Processing in Tunnel Mode). Instead, it refers to the IPsec connection. IPsec is a suite of related protocols for cryptographically securing communications at the IP Packet Layer. IPsec also provides methods for the manual and automatic negotiation of security associations (SAs) and key distribution, all the attributes for which are gathered in a domain of interpretation (DOI). The IPsec DOI is a document containin...
