We just had a hard drive failure on our exchange machine. We bought a new hard drive and reinstalled the OS. Now we are reinstalling exchange. I ran ForestPrep with no issues.
When I go to run DomainPrep, I get the following error message.. "Setup failed while installing sub-component domain-level permissions"..
I researched on Microsoft and found that 2 users need to been in AD under users(which they are).. Question, Since these users where probably created with the first exchange install, should I have deleted them first before running ForestPrep?
