I dont think that is possible once you have exchange installed.Sukh

I wouldn't even consider installing Exchange on to a renamed machine. If you have run DCPROMO on it and do not want it to be a domain controller, then run DCPROMO again, remove it and then drop it out of the domain and rebuild it. If you have simply added it to the domain, then drop it in to a workgroup, wipe and rebuild. I have simply seen too many issues, particularly with IIS with renamed machines.
