Snow Inventory Client Service is unable to start on a Domain Controller

On a domain controller, on which the Snow Inventory Client is installed, the service fails to start with the regular "NETWORK SERVICE" or "SYSTEM" account. It is, however, possible to change the "Log on as" setting for the service to a domain administrator account, and the service will start:

If the [default] Local System account is used, when trying to manually run a scan through an elevated command prompt (client.exe /scan), the following errors may be seen in the client.log file:

18:13:58 : ERROR: client64 Cannot load config 'client.config'.
18:14:04 : ERROR: client64 Cannot launch '"C:\Program Files\INVENTORYCLIENT\Scanner64.exe" /RUN' (0). The operation completed successfully.
