Install Exchange Server 2013 Management Tools when there is no DC at your site

Trying to install the Exchange 2013 Management Tools, I kept receiving an error that setup couldn't proceed because "Setup must use a domain controller in the same site as this computer". The log files indicated "Failed [Rule:DomainControllerIsOutOfSite]". I was trying to install these tools onto a computer in a Site that did not have a DC. Using the unattended setup with /DomainController didn't help, as it wasn't that it couldn't find a DC, but there was no DC in my site. Unfortunately for me, sites were setup for SCCM, and some didn't have DCs. Here is how I finally worked around it and installed the Management Tools quickly, with only changes to the PC - no reboot required.

1. Navigated to HKLM\System\CurrentControlSet\Services\Netlogon\Parameters in the Registry Editor.
2. Created a new String Value (REG_SZ), called SiteName, with a value of the Site where the DC was located.
3. Kicked off the installation again, which completed successfully.
4. Deleted the SiteName registry entry after verifying the Management Tools were installed.




Would this work on a full server installation?  Possibly. However, I certainly wouldn't recommend attempting it for anything other than a critical system outage situation.
