Hi, I had a new install of Exchange 2007 installed on a brand new Windows 2003 SP2 R2 server and it was workingbut never really configured. I unistalled Exchange because we were going to move it to another server but that didn't happen. Now I want to install it again but when I click on setup.exe nothing happens. I have run Setup.com /PrepareSchema and Setup.com /PrepareDomain from the command line without a problem. I tried restarting the server no help, there is nothing in the eventlog. I'm logged in as an administrator. Everything else on the server seems to be working just fine. Thanks Jared
