DriveLock License Management (expire dates) over DOC, within an Enterprise Environment
DES Servers, running into an an protected Enterprise Environment configured according Microsoft's Recommendation
for an Enterprise-Access-Modell, should be able to renew their License Date (Maintenance Date) over the DOC,
without having direct Internet access, and without getting each year a new license to activate by phone.
An Implementation idea is maybe a Windows 10 Client System running DOC Companion, while the Client have
Internet Access over a Company Proxy Server, to renew the License at the DES Server backend.
if you issue a new license annually (or whenever the maintenance is extended), then you don't even need one without activation, because the mmc does the activation and you can run it on a computer with internet access or use the telephone activation. You can either activate by telephone or issue the customer with a license without activation. Subscription licenses have to be reissued anyway, at least until now
