I ran my Exchange best practice analyzer and it complained that I needed to add to the 3/GB switch on two of my 2003 domain controllers. I did, but when I ran it again after I rebooted them, it did not notice the change. They read as follows: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003, Standard" /fastdetect /3GB /NoExecute=OptOut My only guess is that I did not put the switch in the right place. Should I have put it after the "/NoExecute=OptOut"? My last environment was a 2000 AD environment and did not have the /"NoExecute=OptOut"? Any help would be appreciated.
