That is a reasonable business assessed risk. I always want to have at least 2 Domain Controllers even for the smallest non-SBS shops, both of which should be global catalog servers (which provides for Exchange/Outlook to use secondary). Hardware faults can cause software corruption. I don't want rebooting a DC (service pack, patches) to cause email users to have to wait. -----Original Message----- From: adrian bolzan [mailto:abolzan@xxxxxxxxxxxxxxxxxxxxxxxxx] Sent: Tuesday, March 08, 2005 10:03 PM To: [ExchangeList] Subject: [exchangelist] RE: Windows 2003 Active Directory http://www.MSExchange.org/ Hi Peter, I agree that two DC's would be better than one, however, that is not really an option- i.e. another AUD$1100 for a Windows server license just to have another DC. We are not a big shop so I am hoping that one DC will be enough, at least until my next budget period. Again, hardware faults aside, I assume that Windows 2003 is stable enough not to fail.
