I am currently trying to install Exchange Server 2000 Enterprise on my PDC of my network which is running Win2k Server. I also run IIS, DHCP, and DNS off of this machine. Everything runs fine during the install until it tries to expand the Active Directory Schema. It successfully expands file 2/10 but I get a blue screen immediately when it starts to expand file 3/10. (Blue Screen is “Kernel Uncaught Exception”) I have tried running setup with “setup /forestprep” and it crashes at the same point. I saw a reference on MS’s site on how to expand the Active Directory manually when your using Active Directory Connector for Exchange 5.5 but nothing for when your installing Exchange 2000. I am really needing to get this up and running ASAP and not surprisingly MS has been of no help to this point. Any help would be greatly appreciated.
