+Servidor: VM `Windows Server`, dominio `lci.lasalle.mx`, DC `192.168.50.10`.
+Cliente: VM `Windows11-002`, Windows 11 Enterprise LTSC, build 26100,
+nombre de equipo `DESKTOP-LM7D7OM`, inicialmente en WORKGROUP.
+
+Antes de la prueba se creó el checkpoint
+`Before SGU unified enrollment 2026-09-10`. El cliente sólo tenía conexión al
+`Default Switch`; se añadió la tarjeta `SGU AD Test` al switch `Laboratorio AD`
+y se configuró administrativamente `192.168.50.202/24` sin puerta de enlace.
+Esta preparación de la red del laboratorio es independiente del bootstrap:
+el enrolador no asignó esa dirección y no recibió parámetros de IP del cliente,

+Se ejecutó el paquete con la IP del DC, una credencial en memoria y
+`-SkipRestart` para inspeccionar el resultado; después se reinició el cliente.

+- Selección automática de `Laboratorio AD` y descubrimiento autenticado de

+- Proveedor y certificados instalados; salud mTLS verificada antes de la unión.
+- Unión al dominio completada y `Test-ComputerSecureChannel` verdadero después
+  del reinicio.
+- `Test-SguClientEnrollment.ps1` con exigencia de dominio, broker, acceso remoto
+  y RustDesk: `IsValid=True`, sin incidencias, después del guard de arranque.

 - `sgu-server-bootstrap-$Version.zip`: crea el bosque AD/DNS, OUs, grupo RDP, GPO, recurso `Packages`, broker mTLS y administración remota; se reanuda solo después del reinicio.
-- `sgu-client-bootstrap-$Version.zip`: registra un certificado mTLS único, instala y valida el Credential Provider antes de unir el equipo al dominio, habilita RDP/WinRM y se repara al arranque.
-- En clientes Hyper-V con dos NIC, el bootstrap selecciona la red privada sin puerta de enlace, solicita o acepta la IP fija del cliente, espera a que la dirección y WinRM estén disponibles y conserva en pantalla y archivo cualquier error de enrolamiento.
+- `sgu-windows-client-bootstrap-$Version.zip`: paquete único para Windows 10 1607+ y Windows 11 x64 Pro, Enterprise o Education, con LAN, VPN existente y Azure P2S opcional.
+- Doble clic en `Start-SguClientEnrollment.cmd`, IP del servidor y credenciales: descubre el dominio autenticado, comprueba las interfaces y rutas disponibles y conserva DHCP, las IP del cliente y el DNS de Internet. Ya no solicita una IP del cliente.
+- Conserva seguridad mTLS, Credential Provider, cuenta estándar, RustDesk, supervisión y autorreparación. El servidor debe estar preparado con SGU y ser accesible por LAN o VPN.
 - `sgu-linux-client-bootstrap-$Version.zip`: une clientes Debian/Ubuntu o RHEL/Fedora/Rocky/AlmaLinux con realmd, Kerberos y SSSD. Solicita interactivamente la contraseña de unión y no instala el Credential Provider de Windows.
 - `sgu-azure-infrastructure-$Version.zip`: despliega mediante Bicep una VM Windows Server 2025, red privada, IP pública protegida por NSG y Azure VPN Gateway P2S; también genera certificados por equipo y descarga el perfil de cliente.
 - El bootstrap Azure conserva la IP privada administrada por la NIC de Azure, autoriza el pool P2S en los firewalls SGU y nunca publica LDAP, Kerberos, SMB, RPC, WinRM ni el Auth Broker directamente a Internet.
-- Los Windows 11 Pro pueden instalar un perfil IKEv2 de todos los usuarios con certificado de máquina, DNS dividido para `lci.lasalle.mx` y ejecutarlo desde la pantalla de inicio de sesión antes de autenticar una cuenta de dominio nueva.
+- Windows 10 y 11 pueden instalar el perfil IKEv2 de todos los usuarios con certificado de máquina y DNS dividido del dominio; la disponibilidad antes del inicio de sesión depende del perfil y de las políticas del equipo.
 - El Auth Broker clasifica sin tareas programadas cada cuenta autenticada: `AL` se agrega a `SGU-Alumnos`, `AD` a `SGU-Administrativos` y `DO` a `SGU-Docentes`; el bootstrap crea cada grupo dentro de la OU de su rol y migra idempotentemente cualquier grupo heredado sin cambiar su SID.
 - El Auth Broker resuelve la dirección guardada de administrativos y docentes mediante `GetDireccion`, `GetLocalidadListado` y `GetColoniasListado`, evitando conservar los valores transitorios `Seleccione...` de los controles dinámicos de SGU.
 - El enrolamiento y la reparación de clientes Windows crean y verifican idempotentemente la cuenta local estándar `alumno`, sin pertenencia al grupo de administradores.
