This week's newsletter is all about deploying Active Directory in the cloud using Windows Azure. Unfortunately I couldn't find any funny cartoons about Active Directory, but I did find this Dilbert strip that shows how your company directory can sometimes be used for nasty purposes:
From the Mailbag
We're still getting lots of feedback from our issue Tiptoeing Towards Windows 8 (Issue #932). Mark, a network admin working in Virginia, USA, says:
I enjoyed reading your article. I had a similar experience switching from Windows XP to Windows 7 in that I had to think a bit about how to perform certain basic tasks simply because it was different. One blog I read on the subject said that Windows 7 was more "intuitive". IMHO, Windows XP was far more intuitive if only because after years of working with it, it BECAME intuitive. Bottom line: I chalked up a great deal of my frustration to that age old IT nemesis, the learning curve. As you said, "maybe the cognitive dissonances that annoy me in Windows 8 are chimeras that will vanish in the wind as I begin working in earnest with the platform."
I basically agree since there's always a learning curve with any new release. It's just that for many folks the learning curve for Windows 8 seems to be steeper than usual...
Tony, who works in the UK, shared as follows:
I have been trying to use Windows 8. I can see what Microsoft is trying to do, and really want to go along with it. One of the differences between "touch" i.e. Windows 8 etc and "mouse" i.e. Windows 7 and earlier -- touch is imprecise and mouse is precise. Thus, apart from the autohide task bar (which some of us used e.g. on smaller screen laptops), the mouse guides the cursor to a precise point and clicks. Thus it is very easy to pick from a long list of things e.g. programs on the start menu. A finger on most touch screens is too coarse to do the same. Thus any touch screen approach cannot have anything like as many discrete "areas" on the screen as we are used to. To compensate for this, touch has the concept of swiping to one side to get to additional screens.
But I think that what is making it difficult is that whilst swiping off screen is intuitive for touch, using a mouse to drag the cursor to nebulous areas of the screen is conceptually quite difficult. Here you have a precise pointer, but you are expected to move it to somewhere not clearly defined.
I have thought of something that would make the transition much easier -- if the start menu background was not a solid colour, but a colour gradient to where the active off screen areas are (and heresy a word in semi-transparent text to indicate what the area does) would make it far more logical. This could easily be switched in and out -- get rid of it when you are used to it.
And probably few people ever realised that the Windows taskbar could be put down the side -- it does not have to be at the bottom. So why can't we have the "off screen" trigger configurable -- then most of us could put it in the bottom left on our desktop machines.
In a few years we will have all got used to it. But if you look back at XP, it has an option for "classic menu" because some people took time to adjust from Windows 2000 to Windows XP. If that was a problem, then it should have been obvious that the more radical change in Windows 8 (and Server 2012) would take more getting used to. I think the other thing that was forgotten -- many of us switch backwards and forwards between different versions of Windows -- especially consultants and anybody in IT support. If you make a switch and use it all day, every day, then the change is easier to get over.
From what I understand, the Windows 8.1 release is going to address the "nebulous area" and background issues that Tony describes above, so let's keep our fingers crossed and hope for the best.
And a reader named David said:
For all the good and/or bad about Windows 8 and its interface, the thing I keep coming back to is why Microsoft insists on making everyone change when clearly many people don't want to change. What would be wrong with leaving the options in place so that you could easily have Windows 8 look like 7, or Vista or XP or even 95. For IT professionals and people who are using different systems all the time a change is maybe annoying but can usually be done without too much problem. For Mr/Mrs Average who don't understand systems very well, a major shift like this can massively reduce their productivity.
My guess here is that it's simply too costly for Microsoft to continue to include legacy UI elements in Windows 8 because doing so would add considerably to the test matrix for debugging builds. But I agree that Mr/Mrs Average might have a hard time adjusting to Windows 8. I've also heard however that their kids love it.
Anyways, keep sending us your feedback to [email protected] if you have more to say on the matter, thanks!
Active Directory and the Cloud
My how times have changed. Companies used to deploy their domain controllers on-premises, but now they can deploy some or all of them in an Infrastructure as a Service (IaaS) cloud. This can have huge ramifications for organizations that have a global reach or whose users often travel to far-away places and need to authenticate where the organization has no local Active Directory infrastructure.
Deploying a portion of your company's Active Directory infrastructure to the cloud is simple. All is requires is deploying your domain controllers on Windows Azure virtual machines and setting up site-to-site VPN connectivity between your on-premises and Windows Azure infrastructures. You need to use Windows Azure Virtual Network to establish this connectivity however. That's because Windows Azure virtual machines don't support static IP addresses, and while domain controllers are supposed to always have static addresses, using Windows Azure Virtual Network ensures that the dynamic addresss assigned to these domain controllers will last for the lifetime of the virtual machines. There are a few other considerations you'll need to be aware of and you can read all about it in this whitepaper on MSDN:
But that's not the only way of doing it. There's also a new offering from Microsoft called Windows Azure Active Directory (Windows Azure AD) that can provide your organization with a single identity service that works across Windows Azure, Microsoft Office 365, Dynamics CRM Online, Windows Intune and 3rd party cloud services. You can integrate Windows Azure Active Directory with your existing on-premises Active Directory environment, and you can use it to provide your users a seamless single sign-on (SSO) experience across Microsoft Online Services, third party cloud services, and applications built on Windows Azure that leverage web identity providers such as Microsoft Account, Google, Yahoo!, and even Facebook. You can find out more about Windows Azure Active Directory here:
Finally, you might want to read Sander Berkouwer's summary article concerning it here:
How do you get started with Windows Azure Active Directory? Keith Mayer has a good walkthrough explanation and whiteboard video in his blog here:
We're going to hear from Keith soon in a guest editorial he's writing for an upcoming issue of WServerNews, so stay tuned.

Tip of the Week

The following tip was submitted by reader Quentin Gurney who is an enterprise IT architect currently working for a Fortune 100 company:
Windows updates not installing due to local computer WSUS database corruption
Perhaps you have run into this issue. You cannot install Windows updates and there is an error in the application log that suggests there is something wrong with the database.
Error code requiring this fix:
Log Name: Application
Date: 6/18/2009 3:22:06 AM
Event ID: 474
Task Category: Database Page Cache
wuaueng.dll (340) SUS20ClientDataStore: The database page read from the file "C:\Windows\SoftwareDistribution\DataStore\DataStore.edb" at offset 4595712 (0x0000000000462000) (database page 1121 (0x461)) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch. The expected checksum was 2818733426791738953 (0x271e271e0c70ee49) and the actual checksum was 1089324781602401865 (0x0f1e0f1e0c70ee49). The read operation will fail with error -1018 (0xfffffc06). If this condition persists then please restore the database from a previous backup. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.
There indeed is something wrong with the database, but how do you fix a windows internal database for WSUS? There is not much documentation on the subject and what there is suggests you might need to rebuild the whole O/S to make it work. When I ran across this, I was not very interested in doing that kind of a rebuild so I did some more digging.
I found some information that suggested that the local machine WSUS DB might be the same DB that Active directory uses or Exchange uses. To fix that kind of dB, I found this entry suggesting I needed to use esentutl.exe which on a DC is front ended by ntdsutil:
Found this KB and got the idea to try repairing the JET DB:
- First, got on a Domain Controller because the tool I needed was installed there.
- Mapped c: drive on problem server as z:
- On the problem server box shut down cryptographic service, BITS, Windows Updates. (I had to set windows updates to disabled – kept restarting and opening the file)
- Executed following command:
C:\Users\my account>esentutl /p z:\windows\softwaredistribution\datastore\datastore.edb

Integrity check successful.
It is recommended that you immediately perform a full backup
of this database. If you restore a backup made before the
repair, the database will be rolled back to the state
it was in at the time of that backup.
Operation completed successfully in 61.75 seconds.
After that, restarted services and we are now installing windows updates. This saved me a few hours by avoiding a rebuild. Server is working fine.
