Windows Server 2012 at a glance : Part 1

Tumbling arround the net and trying to get an overview over Windows Server 2012, I decided to create a quick summary containing the top links and a short summary about Windows Server 2012. The ultimate goal (at least for myself) is mastering the MCP 70-410...

Editions

Windows Server 2012 comes in the following editions:

Foundation
Essentials
Standard
Datacenter

A very good overview about the possibilities and difference can be found here (in German):

Hyper-V

One of the more prominent roles is the Hyper-V role. Wikipedia offers a nice article about the Microsoft way of virtualization under the following link:

http://en.wikipedia.org/wiki/Hyper-V

Basics

Basic arcitecture of Hyper-V

Quite impressive is the scalability of Hyper-V Server 2012 in regards to the maximum ammount of memory and disk size of a virtual machine:

1 TB Memory
64 TB Disk Size

Hyper-V contains two type of network adapters:

Synthetic Network Adapter
Legacy Network Adapter

Differences are nicely explained in the link below (German):

Configuration

Ping me baby

Did you know how to enable the pinging of a server, which by the way is disabled by default?

It's all about the Windows Firewall with a new Inbound Rule Set, "File and Printer Sharing (Echo Request - ICMPv4-In) ((Or v6-In, if you'r into IPV6)).

Manage Windows Store Apps

Application Control Policies contain a new feature called "Packaged app Rules". We're able to deny or allow specific Widnows 8 Store Apps to be installed on a Windows 8 Client:

Active Directory

As usual, we start with the basics of the according Wikipedia entry for Active Directory:

http://en.wikipedia.org/wiki/Active_Directory

AD is structured in:

Forest
Tree
Domain
OU
Object

Service Locations (SRV) in Active Directory map the name of a service to a name of a server offering this service.

WinRT: Transport Security with Basic Authentication

Wieder mal viel gelernt:

http://msdn.microsoft.com/en-us/library/ms733775.aspx

Nur schade, dass für eine Windows 8 Store App ein valides Zertifikat vorausgesetzt wird:
http://social.msdn.microsoft.com/Forums/en-US/winappswithhtml5/thread/b6887fa1-1b29-4747-a0f3-573e77cd10ea/

Um dies zu umgehen, kann der Klassiker eingesetzt werden: Fiddler! Allerdings benötigt dieser ein Add-On, damit der Traffic der in einem eigenen Prozess laufenden Windows 8 Store Apps, auch mitgelesen werden kann.

Classics => B.O.F.H

It's backup day today so I'm pissed off. Being the BOFH, however, does have it's advantages. I reassign null to be the tape device - it's so much more economical on my time as I don't have to keep getting up to change tapes every 5 minutes. And it speeds up backups too, so it can't be all bad can it? Of course not.

A user rings

"Do you know why the system is slow?" they ask

"It's probably something to do with..." I look up today's excuse ".. clock speed"

"Oh" (Not knowing what I'm talking about, they're satisfied) "Do you know when it will be fixed?"

"Fixed? There's 275 users on your machine, and one of them is you. Don't be so selfish - logout now and give someone else a chance!"

"But my research results are due in tommorrow and all I need is one page of Laser Print.."

"SURE YOU DO. Well, you just keep telling yourself that buddy!" I hang up.

You'd really think people would learn not to call..

The phone rings. It'll be him again, I know. That annoys me. I put on a gruff voice

"HELLO, SALARIES!"

"Oh, I'm sorry, I've got the wrong number"

"YEAH? Well what's your name buddy? Do you know WASTED phone calls cost money? DO YOU? I've got a good mind to subtract your wasted time, my wasted time, and the cost of this call from your weekly wages! IN FACT I WILL! By the time I've finished with you, YOU'LL OWE US money! WHAT'S YOUR NAME - AND DON'T LIE, WE'VE GOT CALLER ID!!"

I hear the phone drop and the sound of running feet - he's obviously going to try and get an alibi by being at the Dean's office. I look up his username and find his department. I ring the Dean's secretary.

"Hello?" she answers

"Hi, SIMON, B.O.F.H. HERE, LISTEN, WHEN THAT GUY COMES RUNNING INTO YOUR OFFICE IN ABOUT 10 SECONDS, CAN YOU GIVE HIM A MESSAGE?"

"I think so..." she says

"TELL HIM `HE CAN RUN, BUT HE CAN'T HIDE'"

"Um. Ok"

"AND DON'T FORGET NOW, I WOULDN'T WANT TO HAVE TO TELL ANYONE ABOUT THAT FILE IN YOUR ACCOUNT WITH YOUR ANSWERS TO THE PURITY TEST IN IT..."

I hear her scrabbling at the terminal...

"DON'T BOTHER - I HAVE A COPY. BE A GOOD PERVY AND PASS THE MESSAGE ON.."

She sobs her assent and I hang up. And the worst thing is, I was just guessing about the purity test thing. I grab a quick copy anyway, it might make for some good late-night reading.

Meantime backups have finished in record time, 2.03 seconds. Modern technology is wonderful, isn't it?

Another user rings.

"I need more space" he says

"Well, why not move to Texas?" I ask

"No, on my account, stupid."

Stupid? Uh-Oh..

"I'm terribly sorry" I say, in a polite manner equal to that of Jimmy Stewart in a Weekend Family Matine Feature "I didn't quite catch that. What was it that you said?"

I smell the fear coming down the line at me, but it's too late, he's a goner and he knows it.

"Um, I said what I wanted was more space on my account, *please*"

"Sure, hang on"

I hear him gasp his relief even though he'd covered the mouthpeice.

"There, you've got *plenty* of space now!"

"How much have I got?" he simps

Now this *REALLY* *PISSES* *ME* *OFF*! Not only do they want me to give them extra space, they want to check it, then correct me if I don't give them enough! They should be happy with what I give them *and that's it*!

Back into Jimmy Stewart mode.

"Well, let's see, you have 4 Meg available"

"Wow! Eight Meg in total, thanks!" he says, pleased with his bargaining power

"No" I interrupt, savouring this like a fine red at room temperature, with steak, extra rare, to follow; "4 Meg in total.."

"Huh? I'd used 4 Meg already, How could I have 4 Meg Available?"

I say nothing. It'll come to him.

"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaagggggghhhhhH!"

I kill me; I really do!
