have installed exchange 2007 on a new 64x box. DC, DNS, DHCP
andExchange 2003 were in another box. Exchange 2003 was running
fine before installing Exch2007.
The installation of Exch2007
setup process went fine. It copy allmailboxes etc. However Im not able
to demote 2003 because of this error:Setup failed while installing
sub-component Domain-level permissionswith error code 0x80072030
(please consult the installation logs for adetailed description). You
may cancel the installation or try thefailed step again.
