We have installed windows 2003 64 bit evaluation enterprise on one of our server and also we have installed exchange 2007 and made all configuration and everything is tested working fine and we also made it live now and working. Now this server is loaded with a full windows 2003 AD along with fully configured exchange server along with GFI mail essentials and mail security.Last week we got our volume license key along with original cd. Please advise, is there any other way we can convert this trial to licensed without repairing OS as I put repair I am afraid that if it is not installed successfully. So, Please advise what is the best solution for this scenario Awaiting your reply
