# `RestrictRemoteClients` enum

GPO policy: "Restrict Unauthenticated RPC clients" under Computer Configuration > Administrative Templates > System > Remote Procedure Call. Controls whether the RPC runtime on a server restricts unauthenticated RPC clients connecting to that server. Helps prevent anonymous access to RPC-exposed services. Registry: HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Rpc:RestrictRemoteClients (REG_DWORD). CIS Benchmark recommends value 1 (Authenticated) for most environments. Reference: [Policy CSP - RemoteProcedureCall](https://learn.microsoft.com/en-us/windows/client-management/mdm/policy-csp-remoteprocedurecall)

## Values

| Enum Value | Description |
|---|---|
| `NONE` | None (registry value 0). No restrictions on remote RPC clients; anonymous connections are allowed. Default on Windows Server 2003 SP1 and older. |
| `AUTHENTICATED` | Authenticated (registry value 1). Only authenticated remote RPC clients are allowed; anonymous calls are rejected except those arriving over named pipes (ncacn_np). Default on Windows Vista and later. CIS L1 recommended value. |
| `AUTHENTICATED_WITHOUT_EXCEPTIONS` | Authenticated without exceptions (registry value 2). All anonymous remote RPC calls are rejected with no exceptions — including calls that would otherwise be allowed over named pipes. Most restrictive. |
