I installed the first exchange 2003 server in a new active directory environment and then realized that I did not choose my D drive as the install location for my data. So I uninstalled exchange so i could reinstall the data on my partitioned D drive. When I try to install it says to install the first exchange server in a domain, or to run setup in "/forestprep" mode, you must be an exchange full administrator at the organization level. You must use an account that has been granted the full exchange administrator role on the exchange organization using the exchange administration delegation wizard.
I just installed exchange with this account. How do I assign the permissions I need to install exchange?
