We have two Exchange 2010 Servers (HT, MB, CA) running on Windows Server 2008 R2. While trying to install Symantec Backup exec 2010 R3, we had to define the "Manage Auditing and Security Logs" via User Rights Assignment in Group Policy. We managed to install the Backup Exec just fine biut noticed that the Exchange started actig up. It is no longer able to mount the databases and is giving an error code of 0x80004005. A search of this error mentions somting to do with the problem being due to the fact that domainname\exchnage servers is not been given the assignment I mentioned earlier. I would like to find out what other user rights are required by exchange so I can restore them. For now, our Exchange Servers are unable to run most of the services.
