I installed an exchange 2007 into a new environment. I then without thinking removed all the HD's in the machine to make room for larger drives. I didn't think anything of it and proceeded to install exchange again with a different name. Now when I look into the Exchange management console it is listed there. I get a few different error messages but I cant remove it for some reason. I deleted it out of AD after the fact. What do I need to do in order to remove it completely?
