Needed some advice and have not been able to find answers on Technet. I've just installed ISA 2000 (plus patches) on Windows Server 2003. I now need to change the hostname of the system. This system is a stand-alone server in an existing NT4 (I know, don't bother) domain. I'm picking up the support from an existing employee and saw that I am unable to administer the array within ISA Management because of a system name change. I have checked fixes for a system in an AD environment, however, cannot find answers when this condition exists in an NT4 domain. I'd greatly appreciate any assistance.
