I have tried everything to get this fairly fresh Exchange server install running again, but nothing works, I cannot even join the active directory anymore, while it works fine for all other machines on that domain. The TCP/IP and DNS settings are perfectly fine. I am thinking about actually disabling/removing (maybe moving) the virtual machine and installing a machine with the same hostname on the server and install Exchange on that machine. A proper installer is unfortunately no longer possible since I am unable to join the domain at all. So I What should I do on the active directory domain controller to remove all previous data related to Exchange? If you have any advice that could help me being able to join the domain, that would be welcome as well. The firewalls are off and the computer does appear in the list of computers on the domain controller, but after rebooting and joining a domain it never gets pass "Applying computer settings". When having joined a workgroup, it boots pretty quickly. This server was installed the same day as a replacement for another Exchange server that was uninstalled properly (had to boot VM to uninstall, because 2 exchanges appeared in EMC). Problem: When in a domain the bootup never gets pass "Applying computer settings".

Hi ujjain, "I have tried everything to get this fairly fresh Exchange server install running again, but nothing works, I cannot even join the active directory anymore," "disabling/removing (maybe moving) the virtual machine and installing a machine with the same hostname on the server and install Exchange on that machine." Do you mean the Exchange server was failed ago and you just remove the VM? Which version of Exchange server do you use? If possible, please rename hostname of the server.
