Move Outlook calendar

Howto migrate calendar meetings without losing the Option "Send Update"

It is always part of the outlook administration job to either move, recover , repair and migrate outlook mailbox or PST. It is worthwhile mentioning that after the migration of the outlook mailbox or PST to another Mailbox or PST everything will probably look fine. Having said that, there is one thing that seldom works correctly. You may notice that in the newly migrated mailbox, all the meetings will be missing the "send Update" option. Because of this, you will be unable to send updates to the meeting attendees. The usual error is that the meeting request is not sent. The work around is simple but it is rarely mentioned on the support sites. Here is the workaround:

Inorder to migrate appointment from one mailbox/PST to anothermailbox/PST without losing the Option "Send Update" incalendar meetings, you need to make sure that you move the calendar items notcopy/paste or export/import. If you do a copy/Paste orImport/Export you will be unable to send updates to the meeting attendees inthe destination calendar

Lets see the procedures to move theoutlook calendar items

1) Just switch the calendar view tocategory view and move all the calendar items by performing the belowsteps

Click on View->current view -> by category
click on Edit->Select all ->Cut

2) Than go to the targetcalendar and paste it

Click on View->current view -> by category
click on Edit -> paste

Clickon View->current view -> day/week/month

Nowyou can open any appointment and be able to "Send Update"to the meeting attendees

Creating Site‐to‐Site VPNs with Pre‐Shared Keys @ Cisco Router

2011-07-26T08:27:00.001-03:00

Documentation:

     1. Document your IKE Phase 1 negotiation criteria (example below)
         • Hashing: SHA‐1
          • Authentication: pre‐shared
          • Key exchange: Diffie‐Hellman Group 2

     2. Document your IPSec (IKE Phase 2) negotiation criteria (example below)
          • Encryption algorithm: esp‐aes 128
          • Authentication: esp‐sha‐hmac

Configuring IKE Phase 1:
     1. Enable ISAKMP
          • Router(config)#crypto isakmp enable
     2. Create ISAKMP Policy : Router(config)#crypto isakmp policy <1-10000>
          • Router(config)#crypto isakmp policy 100
          • Router(config-isakmp)#encryption aes 128
          • Router(config-isakmp)#authentication pre-share
          • Router(config-isakmp)#group 2
          • Router(config-isakmp)#hash sha
          • Router(config-isakmp)#exit
     3. Configure ISAKMP Identity: Router(config)#crypto isakmp identity <address/hostname>
          • Router(config)#crypto isakmp identity address
     4. Configure ISAKMP Key: Router(config)#crypto isakmp key 0 <Pre-Shared-Key> address <remote IP address>
          • Router(config)#crypto isakmp key 0 SUPERSECRETKEY address 1.1.1.2

Configuring IKE Phase 2:
     1. Create transform sets: Router(config)#crypto ipsec transform-set <name> <methods>
          • Router(config)#crypto ipsec transform-set SET-NAME esp-aes128 esp-sha-hmac
          • Router(cfg-crypto-trans)#mode tunnel
          • Router(cfg-crypto-trans)#exit
     2. (optional) Configure IPSec lifetime : Router(config)#crypto ipsec securityassociation lifetime <seconds/kilobytes> <value>
          • Router(config)#crypto ipsec security-association lifetime seconds 86400
     3. Create mirrored ACLs defining traffic to be encrypted and the traffic expected to be received encrypted. Router(config)#ip access-list extended           <name>,
Router(config)#permit ip <source network | wildcard> <destination network | wildcard>
          • Router(config)#ip access-list extended S2S-VPN-TRAFFIC
          • Router(config-ext-nacl)#permit ip 172.30.2.0 0.0.0.255 192.168.1.0 0.0.0.255
          • Router(config-ext-nacl)#exit
     4. Set up IPSec crypto‐map : Router(config)#crypto map <name> <seq> ipseciskmp
          • Router(config)#crypto map S2S-VPN 100 ipsec-isakmp
               o Router(config-crypto-map)#match address S2S-VPNTRAFFIC
               o Router(config-crypto-map)#set peer 1.1.1.2 <remote IP>
               o Router(config-crypto-map)#set pfs group2 <group1/2/5optional>
               o Router(config-crypto-map)#set transform-set SET-NAME<set>

Apply to Interface:
     1. Apply crypto‐map to interface
          • Router(config)#int fa4
          • Router(config-int)#crypto map S2S-VPN

Create Interesting Traffic:
     1. Ping from source network to destination network.

Verify:
     2. Show and debug commands (QM_IDLE is good)
          • Router#show crypto isakmp sa
          • Router#show crypto ipsec sa
          • Router#debug crypto isakmp
          • Router#debug crypto ipsec
          • Router#show crypto map
          • Router#show crypto isakmp policy
          • Router#show crypto ipsec transform-set
          • Router#clear crypto sa

Certificaciones de Microsoft

2011-07-11T16:59:00.003-03:00

Microsoft divide en varios grupos tanto las certificaciones, charlas y cursos de capacitación, como así también el contenido técnico en sus diversos portales (technet, blogs, forums, etc.)

Estos grupos, según el site de certificaciones oficial, son:

Microsoft Office

Server and Windows Technologies

Developer tools and applications

Windows client

Microsoft Dynamics

Security and other solutions

De las certificaciones que nos ocuparemos en este post es de las dos más comunes que se desprenden del grupo Server and Windows Technologies:

MCITP (Microsoft Certified IT Professional): Server Administrator (antes llamada MCSA: Microsoft Certified Systems Administrator)

MCITP (Microsoft Certified IT Professional): Enterprise Administrator (antes llamada MCSE: Microsoft Certified Systems Engineer)

Cabe aclarar, que desde hace algún tiempo, cada examen nos otorga una certificación como especialista en la tecnología específica que rendimos, éstas certificaciones se llaman Microsoft Certified Technology Specialist (MCTS).

Podemos consultar todas las certificaciones MCTS acá.

Ahora bien, en lo que uno generalmente se confunde es en los números y nombres de los cursos, exámenes, certificaciones y libros. Veamos:

Uno puede certificarse sin hacer ningún curso. Para esto, debe registrarse en www.prometric.com y sacar un turno en alguno de los Centros Autorizados que Prometric nos indica en nuestra zona.

Hasta acá todo bárbaro, ahora aclaremos qué exámenes son necesarios para obtener las dos certificaciones enumeradas arriba (MCITP: SA y MCITP: EA).

--------------------------------------------------------------------------------

Para MCITP: SA:

Examen 70-640 (Windows Server 2008 Active Directory, Configuring)

Examen 70-642 (Windows Server 2008 Network Infrastructure, Configuring)

Examen 70-646 (Windows Server 2008, Server Administrator)

--------------------------------------------------------------------------------

Para MCITP: EA:

Examen 70-640 (Windows Server 2008 Active Directory, Configuring)

Examen 70-642 (Windows Server 2008 Network Infrastructure, Configuring)

Examen 70-643 (Windows Server 2008 Applications Infrastructure, Configuring)

Examen 70-647 (Windows Server 2008, Enterprise Administrator)

más sólo uno de los siguientes:

Examen 70-620 (Configuring Microsoft Windows Vista Client)

Examen 70-680 (Windows 7, Configuring)

Examen 70-681 (Windows 7 and Office 2010, Deploying)

--------------------------------------------------------------------------------

Ahora que ya entendimos qué exámenes tenemos que rendir para obtener las certificaciones profesionales, expliquemos qué son las MCTS (Microsoft Certified Technology Specialist).

Como comentamos más arriba, estas certificaciones las obtenemos con cada examen que rendimos (no con todos, solo los que Microsoft indica como TS).

Veamos qué certificaciones obtenemos con cada uno de los exámenes necesarios para las dos carreras que estamos viendo:

--------------------------------------------------------------------------------

Para MCITP: SA:

Examen Certificación obtenida

70-640 MCTS: Windows Server 2008 Active Directory, Configuration

70-642 MCTS: Windows Server 2008 Network Infrastructure, Configuring

70-646 Ninguna.

--------------------------------------------------------------------------------

Para MCITP: EA:

Examen Certificación obtenida

70-640 MCTS: Windows Server 2008 Active Directory, Configuration

70-642 MCTS: Windows Server 2008 Network Infrastructure, Configuring

70-643 MCTS: Windows Server 2008 Applications Infrastructure, Configuring

70-647 Ninguna.

70-620 MCTS: Configuring Microsoft Windows Vista Client

70-680 MCTS: Windows 7, Configuring

70-681 MCTS: Windows 7 and Office 2010, Deploying

--------------------------------------------------------------------------------

Es decir, que si rendimos los exámenes necesarios para convertirnos en MCITP: Server Administrator, obtenemos 3 certificaciones:

MCTS: Windows Server 2008 Active Directory, Configuration

MCTS: Windows Server 2008 Network Infrastructure, Configuring

MCITP: SA

y para MCITP: Enterprise Administrator obtenemos 5 certificaciones:

MCTS: Windows Server 2008 Active Directory, Configuration

MCTS: Windows Server 2008 Network Infrastructure, Configuring

MCTS: Windows Server 2008 Applications Infrastructure, Configuring

MCITP: EA

Una de éstas:

MCTS: Configuring Microsoft Windows Vista Client

MCTS: Windows 7, Configuring

MCTS: Windows 7 and Office 2010, Deploying

--------------------------------------------------------------------------------

Bien, sigamos. Vamos ahora con los cursos. Éstos se denominan Microsoft Official Course (MOC).

Generalmente uno se inclina a realizar los cursos para luego rendir los exámenes y obtener las ansiadas certificaciones y se encuentra con que los cursos sirven para varias certificaciones, que un examen abarca el temario de más de un curso y que los cursos también tienen nomenclatura numerada!

Para esto, vamos a ver también claramente qué cursos comprenden cada examen (y por transitividad, cuáles para cada certificación).

--------------------------------------------------------------------------------

Para MCITP: SA:

Examen Cursos que contiene

70-640 MOC 6425 - Configuring and Troubleshooting Windows Server® 2008 Active Directory Domain Services.

MOC 6426 - Configuring and Troubleshooting Identity and Access Solutions with Windows Server 2008 Active Directory

70-642 MOC 6420 - Fundamentals of Windows Server 2008 Network Infrastructure and Application Platform

MOC 6421 - Configuring and Troubleshooting a Windows Server 2008 Network Infrastructure

70-646 MOC 6430 - Planning and Administering Windows Server 2008 Servers

--------------------------------------------------------------------------------

Para MCITP: EA:

Examen Cursos que contiene

70-640 MOC 6425 - Configuring and Troubleshooting Windows Server® 2008 Active Directory Domain Services.

MOC 6426 - Configuring and Troubleshooting Identity and Access Solutions with Windows Server 2008 Active Directory

70-642 MOC 6420 - Fundamentals of Windows Server 2008 Network Infrastructure and Application Platform

MOC 6421 - Configuring and Troubleshooting a Windows Server 2008 Network Infrastructure

70-643 MOC 6428 - Configuring and Troubleshooting Windows Server 2008 Terminal Services

MOC 6418 - Deploying Windows Server 2008

MOC 6427 - Configuring and Troubleshooting Internet Information Services in Windows Server 2008

70-647 MOC 6437 - Designing a Windows Server 2008 Applications Infrastructure

MOC 6435 - Designing a Windows Server 2008 Network Infrastructure

MOC 6436 - Designing a Windows Server 2008 Active Directory Infrastructure and Services

70-620 MOC 5115 - Installing and Configuring the windows vista operating system

70-680 MOC 6292 - Installing and Configuring Windows 7 Client

70-681 No hay cursos por el momento

--------------------------------------------------------------------------------

Algo que también pueden notar en la numeración de los cursos es que terminan con diferentes letras, éstas indican el “ciclo de vida” de los cursos, es decir que el MOC 6420AK tiene material más nuevo y corregido que el MOC 6420A.

Espero que este post sirva para dar un poco de luz a algo que en principio nos espanta con tantos números y caminos posibles.

Ntsdutil para transferir roles de controladores de Dominio Windows

2010-06-03T00:08:00.000-03:00

En un Active Directory Windows 2000 o Windows 2003, deberíamos tener 2 o mas Controladores de Dominio (DC), mas que funcionalidad de validación de usuarios, por seguridad. Existen 5 roles en un Active Directory que tienen que poseer, al menos, uno de nuestros DCs, estos son:

1.Schema Master. Responsable de las actualizaciones del Active Directory.

2.Domain Naming Master. Se encarga de realizar los cambios de nombre a nivel de Bosque.

3.Infrastruture Master. Actualiza los SIDs a nombres de objetos a través de los dominios.

4.Rid Master. Se encarga de administrar los números RID para los demás controladores del dominio.

5.Pdc Emulator. Emula el PDC para los clientes pre-Windows 2000/Xp.

Existe también la figura de Global Catalog (Catalogo Global) que es una parte de la base de datos de nuestro Active Directory usado para realizar búsquedas en este.

Cuando el DC que tiene los roles, no funciona correctamente, tenemos que transferir los roles a otro servidor que si este funcionando adecuadamente. Podemos usar las diferentes herramientas graficas de administración para realizarlo (255690) o podemos usar en línea de comandos el comando ntdsutil para completar la acción.

En Inico/Ejecutar escribir cmd. Aceptar.

Escribir ntdsutil. Esto nos dará acceso a la herramienta de administración mediante línea de comandos.

Podremos ver los comandos disponibles con ? o help.

El que nos interesa es Roles, para entrar simplemente escribimos roles y pulsamos entrar.

Esta es la parte que nos interesa, lo primero que tenemos que hacer es conectarnos al DC al cual vamos a trasferir los roles, para ello escribimos:

connections

connect to server \\nuestrodc

una vez establecida la conexión escribimos

quit

para volver a la pantalla anterior (Roles).

Ahora transferimos los roles. Tenemos 2 opciones:

•Utilizar Transfer Rol que poniéndose en contacto con el otro DC trasfiere el rol al que estamos conectados. Esta opcion la usaremos cuando tengamos 2 Domain controller encendidos y queramos pasar los roles de uno a otro.

•Seize Rol que fuerza a que el servidor adopte el Rol. Esta es la que usaremos en el caso de que el servidor que tenia los roles este apagado (o fuera de cobertura)

Es decir: si ejecutamos los comandos:

Seize domain naming master

Seize infrastructure master

Seize PDC

Seize RID master

Seize schema master

Forzaremos al servidor al que estamos conectados a adoptar estos roles, si el que los tenia no esta operativo y si ejecutamos:

Transfer domain naming master

Transfer infrastructure master

Transfer PDC

Transfer RID master

Transfer schema master

Nuestro servidor se pondrá en contacto con el DC dueño del rol correspondiente para adoptar ese rol (Útil cuando queremos que un servidor mejor, cumpla ese cometido).

En cualquiera de las 2 opciones nos pedirá confirmación de la trasferencia con un mensaje de Windows, dejándonos un evento en el visor de sucesos. Cuando hayamos terminado escribiremos quit para salir de ntsdutil y exit para salir de la consola

Solo nos queda definir quien va a ser nuestro Global Catalog, esto solo podemos hacerlos desde la herramienta Active Directory Sites and Services (Sitios y Servicos del Active Directory) que suele estar en Herramientas Administrativas. Aquí expandiremos Nombre-predeterminado-primer-sitio / Servers / NuestroServidor, sobre NTDS Settings botón derecho, marcaremos la casilla Catalogo Global y aceptar.

Eso es todo, con estos pasos tendremos el servidor con los roles, podemos confirmarlo desde las herramientas administrativas.

Error visio viewer

2009-11-27T17:41:00.000-03:00

KB973525 Causes Visio Viewer to Fail

The Microsoft security update KB973525, issued on Oct 13 2009, fixes some vulnerabilities in ActiveX running under Internet Explorer.

Unfortunately, a serious side-effect is to make Microsoft’s own Visio Viewer (which runs as an Add-on within IE) refuse to load Visio files. All that we see is a little square with a red cross (in Windows XP) or a failed-image icon (in Windows 2000). Both the 2003 and the 2007 versions of Visio Viewer fail.

Visio Viewer Failed

Until Microsoft issues an official fix, go to Add/Remove Programs and select KB973525 for removal.

Visio Viewer is then much happier:

Visio Viewer OK
