IT Gone BAD.. The UP's and DOWN's (A System Adminstrator's real nightmare)

There are a very few senario's in which IT infrastructure can get really messed up

You make sure you have all the right things in place so that your Domain server does not go down, But no matter how much you try and cry incidents do happen.

like Senario 1 :-

You have a domain controller machine with Exchange running to protect the machine you have connected a RAID card and attached 4 drives, so that even if 1 drive fails the other drive can take over. How can this server still fail ?

Ans - RAID card crashes

(due to the raid card crash, to your bad luck even the exchange databases get corrupt... and you keep crying why me ? )

1) The domain controller is the most important system in the network, hence it was raided with 4 drives (now how the hell would anyone expect a server with 4 raid drives ever hope the server would crash ?), Let me tell you how, to our bad luck the RAID card crashed, Server went down, exchange databases got corrupt, the only good part was that the exchange database was being backed up, but the weekly exchange was failing.... BAAP RE... now wht ?? Luckly we got the support contract renewed with symantec.. guided us to somehow recover the databases.

Senario 2 :-
