How to migrate the DHCP service to Windows 2012

One of my customers asked me to dismiss an old Windows 2003 R2 server which is running the DHCP service for a bunch of workstations and to replace it with a new Windows 2012 server we installed last December.Seen the fact that this DHCP service is configured with many options and a lot of reservations, and that I am totally lazy about recreating all these settings manually, I found a way to dump its configuration to a text file and to import it back to Windows 2012.Let's start exporting the DHCP database from the server that...

Exchange 2013 Client Access Server Role

In a previous article, I discussed the new server role architecture in Exchange 2013. This article continues the series by discussing the Client Access server role. While this Exchange server role shares the same name as a server role that existed in the last two Exchange Server releases, it is markedly different. In Exchange 2007, the Client Access server role provided authentication, proxy/redirection logic, and performed data rendering for the Internet protocol clients (Outlook Web App, EAS, EWS, IMAP and POP). In Exchange 2010,... [Lire la suite]

Exchange 2013 Server Role Architecture

The Past: Exchange 2007 and Exchange 2010 In 2005, we set out developing Exchange 2007. During the preliminary planning of Exchange 2007, we realized that the server architecture model had to evolve to deal with hardware constraints, like CPU, that existed at the time and would exist for a good portion of the lifecycle of the product. The architectural change resulted in five server roles, three of which were core to the product: Edge Transport for routing and anti-malware from the edge of the organization Hub Transport for...

Les DSI sont « sous-évalués » et peu impliqués dans l’entreprise

 Selon une étude d’Ernst & Young si 60% des DSI estiment apporter de la valeur à l’entreprise, la majorité des cadres dirigeants en doutent et préfèrent donc ne pas impliquer les responsables de SI dans les décisions business. Ses compétences et son expérience interdisent-elles au DSI de jouer un rôle stratégique ? Si le système d’information joue désormais un rôle majeur dans un grand nombre d’entreprises, cela ne se traduit pas nécessairement par une plus forte implication des DSI dans la stratégie et les décisions de ces...

Exchange 2013 Server Roles Installation Order – Mailbox First

The Microsoft recommendation regarding the order in which the Exchange 2013 server roles should be introduced into a forest is the reverse of Exchange 2010. Mailbox role first & it does make sense. Why?   In the Exchange 2010 world, the order of installation was CAS, Hub & Mailbox, whereas in 2013, it is Mailbox first & then CAS. Why is it different in 2013? --> Please see the rest on the blog : http://www.howexchangeworks.com/2012/10/exchange-2013-server-roles-installation-order-mailbox-first.html

Client Protocol Architecture In Exchange 2013 : WHERE IS MY HUB ?

Exchange 2013 has only two roles and the protocols handled by the roles are different to the ones in 2010.   In 2013, all types of clients connect to the CAS role. Rather than explaining all the types of access, the below slide from the recent TechEd session by Scott Schnoll shows the client protocol architecture in Exchange 2013. Clearly, a picture is worth a thousand words --> No more Hub, No more UC, things will be eased for deployments... please see the blog... [Lire la suite]
