We have a small office with 15 systems. Now we are planning to connect all these workstations with a server PC that will be running on Windows Server 2008. Now, as this is the first time am getting to Windows Server and all these stuffs, i would like to know what are the risk factors involved if server's Hard Drive got failed or corrupted ? Also what would be scenario if operating system gets corrupted ? Will there be any effect on other systems, if yes, how huge will those be ?
