I have a Dell PowerEdge SC430 that is running AD, Exchange 2003, and is being used for file and print sharing. This server was performing well until today, we came in to find that no one could connect to their mail and all other services were down. When we took a closer look and it appeared that the power had failed and so had our UPS. When I tried to reboot the server it goes through the post and the Dell screen and begins to load windows. After a few seconds it flashes back to the POST and begins to load windows again. Any suggestions?
