comment DNS slow after idling for a few minutes
@GertV We are talking about the client side DNS here. Assuming the client is Windows is the delay immediately present after you issue an "ipconfig /flushdns" in a command-prompt ? This forces the local DNS cache to expire immediately. If that is the case DNS settings client-side are suspect. Either on the client itself or on the DNS server used by the client.

comment DNS slow after idling for a few minutes
That's my first guess too. Also look at the DNS cache expiration time. 2-3 minutes of idling is usually not long enough for the DNS cache to get flushed (5 minutes is pretty standard).

comment Windows shortcut target parameter starting with an @
@MarkHenderson The Caret symbol "^" is the standard "escape the next character" symbol used by then entire WIN32 (and later 64-bit) API since (if I recall correctly) at least NT 3.5 (yes: I'm getting old). It works in just about any place in Windows where you can supply a command-line: CMD-scripts/prompt, WIndows+R run box, short-cuts, in the command-lines associated with services and scheduled tasks, just to name a few.

comment How can you tell what a server actually does?
@AaronCopley Very wise words. I have been there myself. And for the record: I didn't turn them off. I received 8 of the things in a shipping crate. Several failed disks, 3 power-supplies. And 2 couldn't fully recover a dirty raid: They had apparently just yanked the power-cords and the backup-batteries on those raid-controller caches was long dead.

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

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.)
