Thanks to: https://community.spiceworks.com Solution: In Exchange Server 2010, you may also experience this issue if the Exchange Servers group does not have the appropriate permission to the mailbox object in Active Directory. The most common cause for this is broken Access Control List (ACL) inheritance in Active Directory. To check whether inheritance is disabled on the user: Open  Active Directory Users and Computers . On the menu at the top of the console, click  View  >  Advanced Features . Locate and right-click the mailbox account in the console, and then click  Properties . Click the  Security  tab. Click  Advanced . Make sure that the check box for "Include inheritable permissions from this object's parent" is selected. If the user is a member of certain protected groups such as Domain Administrators, it is normal for this box to be unchecked. If you are experiencing a problem with members of these protected gro...

Thank to: https://exchangepedia.com/ In Exchange Server 2003, mail for a recipient can be forwarded to an alternate recipient by modifying the recipient’s  Delivery Options  in  ADUC  | recipient -> properties |  Exchange General  tab. Figure 1:  Use  Delivery Options  to auto forward email to an alternate recipient in Exchange 2003 If you need to forward mail to an external email address, you can’t simply type the address in the  Forward to:  field on the  Delivery Options  page. A  (mail-enabled)   Contact  needs to be created in  AD  first, and Delivery Options modified to point to the Contact. Forwarding mail to an external address in Exchange 2010 and Exchange 2007 In Exchange 2010/2007, these tasks remain the same. However, instead of using  ADUC  to accomplish them, you use the  EMC  or the Shell (aka “ EMS “).  The new term for a Contact is  ...

Thanks to: https://windowserver.wordpress.com/ ¿Conocían que podía crear una instalación virtual de sistema operativo sin instalarlo? Parece confuso ¿No es cierto? pero sin embargo es así Hace ya tiempo, para ser más exactos desde el 22/10/2009, que está disponible un script que permite crear un disco virtual (VHD) directamente desde la imagen de instalación ( INSTALL.WIM ). Esto es, que una vez creado el disco VHD podemos crear una máquina virtual que automáticamente ejecutará SYSYPREP en el primer arranque, dejándola lista para usar (activaciones aparte) Este script al cual me refiero, es válido para Windows 7 / Windows Server 2008 R2 y está disponible en:   Windows(R) Image to Virtual Hard Disk (WIM2VHD) Converter Pues ahora está disponible lo mismo, y mejorado para Windows 8 / Windows Server 2012. Y digo mejorado porque además de más opciones de conversión, permite ejecutarlo tanto para Windows 8 / Windows Server 2012, como para Windows 7 / Windows Server 2...

Thank to: https://networklessons.com WCCP (Web Cache Communication Protocol) is a Cisco protocol that lets you redirect web traffic from clients to a proxy server. Using a proxy server has a number of advantages: Caching: reduces network bandwidth because web traffic that has been requested before can be retrieved from the proxy cache instead of requesting it again from the Internet. Filtering: all web traffic goes through the proxy server first so you can filter certain websites. Monitoring: If you want to know what your users are doing you can track this on the proxy server. WCCP is used between a Cisco router and a proxy server to communicate. The proxy server will tell the router that it is “alive” and ready to serve webpages. It’s also used as a “hello” message so the router knows when the proxy is down. The router is called the  WCCP server  and the proxy is called the  WCCP client . In this tutorial I will first explain the basics of how WCCP forwa...
