Could you please confirm if there is also event ID 1002 with the same error in Application log?
This error related mainly to an old Exchange server object still left in AD, you can use the ADSI edit to go to the following path
“CN=Servers,CN=First Administrative Group,CN=Administrative Groups,CN=EXCHANGE ORG,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=yourdomain,DC=com”
After remove the old records you can restart the Exchange installation.
