recently upgraded (Transition) to exchange 2010. went thru all steps except the last step that was removing the old exchange 2003. Now trying to remove the old 2003 exchange that was also the PDC in past. on one of the last steps, the uninstall from ADD/Remove Progs gives error: Unable to remove server have to remove the recipient update service. When I try to remove the RUS service using the ADSIedit program I do not see CN=Configuration CN=Domain Name or any of the tabs that were referenced online or by Microsoft articales to accomplish the task, I see no reference for the RUS service at all. Thanks for any input.
