I have two virtual Domain-Server 2019 running. Each has an DNS and an Web-Server running.
The first one has also Exchange 2019 and supports the URL: Althoff-Fam.de und the second one URL: country-radio.eu.
It is clear for me, that I need a certificate for each URL and for the Sub-Domains. The first URL will have multiple Sub-Domains the second one currently only www. But I think it would make sence the get for both URLs ‘*’ certificates.
Would these fulfill al requirements or do I need separate certificates for the two DNS-server (ns1 and ns2) and the exchange-server ?
I fugured out an additional problem with my Dyn-Dns provider. I have to setup the TXT bei hand, because currently the external has no access to my internal DNS-server.
If I use separate Sub-Domains I have a big problem to setup the TXT on the provider DNS-server.
Or can I create the certificate for the sub-domains in separate requests?
But than I have to also separate renew requests, or?
