I'm receiving the following error when I try to uninstall an Exchange Virtual Server: Setup encountered an error while checking prerequisites for the component "Microsoft Exchange Server": 0x80072030 (8240): There is no such object on the server. Facility: Microsoft Exchange Cluster Administrator Extension ID no: c103fc97 Microsoft Exchange Cluster Administrator Extension I receive this error when I right click the Exchange System Attendent resource and select Remove Exchange Virtual Server. The Exchange Server Setup Progress.log file contains the following info: [10:23:26] ScPRQ_ServerIsNotHomeServerForPostmasterOfNonEmptyOrg (f:\tisp2\admin\src\udog\excommon\prereq.cxx:2981) Error code 0X80072030 (8240): There is no such object on the server.
