I have an assembled server with Core i7 CPU, 16GB DDR3 and Intel mainboard. It's running Exchange server 2010 SP1 with Windows server 2008 R2. This server is also a one of two DCs in the environment.
The server was working well for about a year. But in the last few days, it became rebooting unexpectedly.
I am not satisfied with the Windows DVD which was used to build the server from the beginning. Now I have a new one.
What shall I do now? Shall I try to upgrade Windows using the new DVD? Or is it possible to re-format it and start installing Windows and Exchange from scratch? What about restoring Exchange to it's previous state in this case?
