Join Centro Beta
So, what is "Centro" you ask...........?
I am glad you asked.... :)
We are looking for a few good testers to help influence the direction of this new Microsoft® Windows Server Solutions Product. Do you have three 64 bit machines that you can spare to test some of the most exciting technology Microsoft is working on? I know the system requirements are a daunting one, but this is the only way we can test "Centro". So, if you are already on the Longhorn Beta or the Exchange Beta, then you are already two thirds of the way there.
The "Centro" Product team is looking to you to help test the Beta of "Centro". “Centro” is the code name for a new Microsoft® infrastructure solution that will help midsize businesses with less than 250 PCs in their environment. Centro will bring together key server products for midsize businesses, including Windows Server “Longhorn,” Exchange Server 2007 and security technologies, plus a new, integrated management experience. Centro is designed for IT professionals in midsize companies, helping them with server technologies that are easier to purchase, install and manage.
