We have installed a window 2008 server in a virtual machine, its having 28 days for activation but its restarting once / twice in a day with out any error. Server configurations are fine for the running process, so reason for the restart is not config issue. even we have 28 days of licence why the machine is restarting itself. plz assist

Hiya, There should be some information in the event log on the server which tells you why its restarting. Or some indication that it was a unexpected restart?

To find the root cause of the problem you should analyze the memory dump file. http://support.microsoft.com/kb/315263 http://knowing-itech.blogspot.com/2011/08/analyze-memory-dump-file-using.htmlhttp://www.arabitpro.com
