Values
| Enum Value | Description |
|---|---|
|
|
Force updated clients (registry value 0). Most secure setting. Blocks RDP connections whenever either the client or server lacks the CVE-2018-0886 CredSSP patch. Both sides must be patched for a session to succeed. |
|
|
Mitigated (registry value 1). Intermediate setting. An updated client cannot connect to an unpatched server, but an unpatched client can still connect to a patched server. Use when you need to allow legacy clients temporarily while the server is already patched. |
|
|
Vulnerable (registry value 2). Least secure setting. Allows all RDP connections regardless of CredSSP patch status on either side. Exposes the host to CVE-2018-0886. Use only as a temporary workaround while applying the CredSSP patch. |
