A while back I installed a copy of exchange 2013 on my domain, we already had an exchange 2010 server on there. As none of the company mailboxes were on there yet it wasn't backed up. The hard drive with it on died and it isn't recoverable.

I have since installed another exchange 2013 server that works fine however how do I go about removing all traces of the old server from my domain?

ADSITEdit is the only way.

I disagree with the above that adsiedit is the only way.

Build a replacement machine in a VM, with the same name.
RESET the computer account in the domain (DO NOT DELETE).
Add the new machine to the new domain.

Install Exchange 2013 (the same version as you installed before) from the command line

setup.exe /recoverserver

That will install Exchange 2013.
Then remove it correctly using add/remove programs.

That is the only way that is supported by Microsoft and it should come out clean. While adsiedit can work, it is a lot of changes and it is very easy to damage your existing Exchange 2010 installation.

Simon is right and if you prefer to install old server again, that is the best way, else ADSIEdit is the last option, however it is a risky option.

I am going to do this today. When I check the version from powershell I get Version 15.0 (Build 712.24) This is a CU. Do I just use the standard RTM to do the recovery?

You need to use the same version as it was. Therefore you will need to use CU2 download. You cannot use RTM as that is too old, the process will fail.
All CU files are the complete product.

The original files are gone, so there is no way to get these back.

You need to create the same directory structure. Therefore you need to create an E drive on the server to allow it to continue.
