comment Should I still have a physical DC, even post-Server 2012?
@TomTom Company I work for is entirely virtual for the AD infrastructure as well. And have been that since W2K3. But we don't use HyperV: ESX all the way. 2 separate sets of ESX cluster-infrastructure on each continent. Each domain has (at a minimum) 3 DC's: 1 DC on another continent and 1 DC in each of the 2 ESX environments on the "home" continent.

comment Unable to install WSUS to windows 2012 r2 server
Seems there is a pending installation of other software keeping the server in a "need to restart" state. This could be a hotfix, or botched earlier software installation, that keeps being re-applied on each reboot so the machine never reaches a "idle" state where it is ready for a change of roles/features. Could even be malware or a root-kit that is causing this. You may be able to find some information in the Event Log but usually this is looking for a needle in a haystack. I strongly suggest you spin up a fresh VM for WSUS. Combining applications on the same VM isn't a good idea anyway IMHO

@jamieb Got it working. It's very easy actually. Will post full answer with working config just in case someone else stumbles across this.

comment Is it valid for a hostname to start with a digit?
@Michael Hampton: You wouldn't believe the shit I see from devs at times. Couple of weeks ago I had one who had made a network-config webpage in a ip-camera so that the user could enter the hostname for the camera. He didn't do ANY validation on the free-format user-input. Beta-test user entered "Room 1.10" and the camera happily send that as DHCP client identifier. I can assure you Microsoft DHCP and DNS servers don't like that. Good thing I noticed before that got into the production build. I can only shudder at the thought what sometimes does get through to the customer...

comment Force the DHCP server to renew the IP address of a client machine, without doing anything in client machine
Unfortunately most DHCP client implementations don't support this extension. Windows systems don't (Upto and including Win7, I'm not sure about Win8, but I don't think MS overhauled the DHCP client that much.)

comment When is a deleted Windows computer-certificate really gone?
continued... The cert guru's (which is not me, I wouldn't know how to troubleshoot this) claim nothing is wrong at all. They have been troubleshooting for several weeks now, but can't find anything. Problem doesn't appear easily reproducible either. AD specialists claim the cert-services are OK too.

comment When is a deleted Windows computer-certificate really gone?
@HopelessN00b We have approx 3000 PC's in 2 different sub-domains of a single forest. All based on same Win7 X64 Pro image through central software distribution. All configurations are the same. Problem so far has shown on some 45-30 of them, randomly distributed across these 2 domains and some 15 OU's. Some are freshly installed in the last 100 days. Others have been running for at least a year. Nothing else is problematic on these. Other certs are OK on these laptops (there are several others for single sign-on to applications and another VPN solution)....
