So, yet another implamentation of exchange, this time i’ve encounted the following error while installing the CAS role on the server.
Setup exited with the following error:
The process does not possess the ‘SeSecurityPrivilege‘ privilege which is required for this operation.
Searching the privilege showed that “Exchange Servers” & more accurate in our situation , the “Domain Administrators“ were not configured in the “Manage auditing and security log” , because the Default Domain Policy & Default Domain Controllers Policy GPO’s was re-created and the default ones were left with the link set to off.
Easy to monitor those privileges with whoami.exe from the support tools, i love it that the server 2008 installs them all as dependencies !
Once we’ve added the Domain\Administrators , Domain\Exchange Servers to the policy , setup ran okay 🙂
