Hi I have an exchange 2003 which during the last year has gone through lots of up and down. End of story, I want to rebuild the system on Monday when no one is at work. The machine is a dual XEON 2.8 with 2 GB of ram. If I recall it properly, these are steps that I need to take. It is not a DC 1.have a full backup of databases 2.to be on safe side, shutdown IIS admin and system attendant service with all dependencies and make a copy off database folder and transactions to be on safe side 3.reinstall windows with service pack 1 keeping the same server name and ip address 4.go in active directory, right click on old exchange system account and choose reset (not sure what this exactly do) 5.join the new machine to domain and reboot 6.install exchange with setup.exe/disaterrecovery switch (I assume there is no need for domain and forest prep) 7.reboot 8.install exchange service pack2 and reboot 9.Right click on first mail box store, dismount, and change the pre-made database location to second drive which old exchange was writing too. Same for public folders 10.run clean up agent on mail server and let it come with red cross on boxes 11.connect them back to users (about 50) Are these steps correct? One last question, do I have to go to every user account and setup email accounts or because active directory has not changed it will come of mail box automatically? Appreciated
