I've got a little SNAFU. I am learning exchange right now, and well... I've by mistake make administrative Groups unavailable or not viewable in both Exchange Manager and in ADSI.This is what I have done 1. Right-click Administrative Groups2.in Administrative Groups Properties dialog box, I clicked Advanced3.In the Advanced Secuirty Settings for Administrative Groupd dialog box, I cleared the Allow Inheritable permission From The Parent To Propagate To This Object and All Child Objects. Include These With All Entries Explicitly Defined Here. After all this I've received a dialog box that prompted me to either Copy, Remove, or Cancel. I clicked Remove, with the end state.I cannot view the Administrative Groups in either ADSI or Exchange System Manager. Anything that would solve this problem without reinstalling Exchange (it is in a test environment, but its for a grade)Thank YouMuch Appreciated
