Server 2008 Freeze Without Apparent Reason

[framosl]

Hi all, I'm a problem with my server win2008 (B. 6002 SP2), 2 mounth ago, this has begin to freeze without an apparent reason. On event viewer there isn't nothing, only a "The previous system shutdown at xx.xx.xx on xx/xx/xxxx was unexpected." before the forced shutdown. This server is my Exchange Server 2007 with all the windows updates, is a virtual machine on ESX too.

On the Reability and Performance Monitor, tab Reliability Monitor, i see only a message "Disruptive shutdown" on the dates that I must restart forced the PC.

There is any that help me to know where is the problem?
