Installing 2010 in co-existence with 2003.
I was provided with a ExPDA report before we ran the /PrepareLegacy /PrepareAD / PrepareDomain commands and this report only had the usual link state suppression messages.
I ran the ExPDA personally afterwards and there was an update so updated it and there is the permissons inheritance block alert:
Access control list (ACL) inheritance is blocked for the Exchange Organization object (CN=Email Environment,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domain,DC=com).
I have seen this before running the schema updates in the past and just allow inheritance as per the MS articles and all is well, I have not, however, seen it AFTER running the Schema updates. Questions:
- No Exchange 2010 servers have been deployed yet as it is a staged approach
- Why was this not on the ExPDA before? Was it the update that brings this check in or has it occurred because of the schema update? I normally see this error before updating the schema and just fix it before the schema update - would fixing it AFTER break anything?
- Is it a requirement to run the /PrepareLegacyExchangePermissions command again after fixing this, or can I just enable inheritance within Exchange 2003 before installing the first 2010 box and that is enough? I need to apply the registry fix and reboot 2003 first so I cannot see the security tab at the moment.
