My calendar is starting to shape up for 2012. If you’re going to be at any IT shows in the first half of the year, here’s where you’ll find me presenting:

• Next week – Oslo, Norway for the Nordic Information Conference
• March 18 – 20 – Ontario, CA for CISOA SecureIT
• March 26 – 29 – Las Vegas for Windows Connections
• April 29 – May 2 – San Diego for The Experts Conference

TechEd is on the radar for a visit at least, but, not confirmed.

If you’re at any of these shows, stop by and say hello!

Happy New Years! I’ve put something up here the past couple years as I wrap up and kick off the new year, so I thought I’d do that again. I had the pleasure of visiting customers, presenting at conferences, and taking a couple quick vacations all over the place last year. I managed to stay mostly in the US this year:

…save for a couple overseas trips:

All told, ~116,406 miles and 90 plane rides.

I sent a mail out to quite a few people who had asked about pictures from all these trips, and I thought I’d share that here – something I’ve not done before.

On the road to San Francisco from Eureka, CA in late March. The road signs called for snow chains which our rented Toyota Camry was sorely lacking. Fortunately the snow was light.

The Grapevine, driving down the 5 to Los Angeles from Bakersfield, CA.

Seals on the beach – driving up Pacific Coast Highway from San Luis Obispo, CA.

On the road from San Luis Obispo, CA to Monterey, CA – driving through Big Sur

On the road to Monterey

The Lone Cypress at Pebble Beach – I had a couple hours to do 17 mile drive before my flight out of Monterey. CA. The airport at Monterey, by the way, has a great little outdoor bar on top of the ramp area.

The Concha y Toro vineyard in Santiago, Chile is conveniently accessible from downtown by Subway.

Viña del Mar about 1:30 drive outside of Santiago, Chile

A somewhat questionable Ascensor I rode down the hill in the port of Valparaiso, Chile

Death Valley – the lowest point in the North America.

Salt Flats in Death Valley – the land of $5.33/gallon for regular gasoline

Another conference week…

The Grand Canyon from a Helicopter. Pat Richard and I did this in October – highly recommended.

The Hoover Dam, by Helicopter

Happy Trails and Best Wishes for a great 2012!

I needed to quickly get the IP addresses of about 100 servers from their names. PowerShell doesn’t appear to have a native Ping cmdlet, but, .Net certainly does. I pasted all the servers into a text file, one per line, and rand the following little loop:

$servers = Get-Content .\serverList.txt
$ping = New-Object System.Net.NetworkInformation.Ping

foreach($s in $servers)
{
    $("$s,$($ping.Send($s).Address)")
}

This loop outputs a comma delimited list of ServerName,IP to the window like this:

TEST-SF6,10.12.3.96
W2003TEST,10.1.34.80
W2003TEST2,10.8.51.27

I pasted the list into a new email in Outlook, highlighted it, and then used the Convert Text to Table feature in Word (and Outlook):

 

Word turned my pasted CSV list into a nice table and I sent it off.

Repeatable, consistent, and predictable are three things that add an incredible amount of value in IT, and building servers from a base image is one way to deliver on this. I was just replying to a thread on a discussion alias where the person who started the thread had reviewed a blog post (http://www.jasonsamuel.com/2010/05/07/how-to-build-a-vmware-vsphere-vm-template-for-windows-server-2008-r2/) on how to build such an image for VMWare. I and a number of people disputed the recommendations made in the referenced blog post in addition to the various other things the individual who started the thread was planning to install in his image/template.

At a high level, the most important thing from my reply, I think, is that you should not be customizing a server for it to be convenient to your work style. The server is there for a purpose driven task. You shouldn’t even be connected to it via Remote Desktop (or sitting at the console) unless you’re troubleshooting a problem which can only be investigated from the desktop. What this means is that all the little utilities and tweaks you have on your desktop should stay on your desktop. Things like PDF readers, Internet Explorer customizations, screensavers and colors, and taskbar preferences, etc. First and foremost, many of these tweaks are profile specific so when you login with a domain account later, after running sysprep, the tweaks will be gone unless you push them into the default profile and in turn push them on to all users. Secondly, when you move on to the next big opportunity, your successor shouldn’t be expected to inherit and adapt (or spend weeks undoing) your personal preferences.

As far as system settings (e.g. page files, network settings, etc.), tweaking or disabling things just because some random guy on the Internet (including me) told you to is not a great idea. When you install an application from a vendor, be it Microsoft or any third party ISV, chances are they made assumptions in their testing that the OS is in a state relatively close to the default install. When you start disabling services (e.g. Indexing, Print Spooler, etc.) by default in an image, you provide a baseline that doesn’t meet this assumption. Rather than customizing by default, customize for specific applications. The settings in an image should be the ones required to operate at a minimum level of functionality on your network (e.g. maybe you need some custom DNS search suffixes to join the domain or settings to meet security standards). This extends to most any system level default. When you’re looking at changing a default setting, I’d first stop and ask yourself “why?”. What’s the reason this is being changed? Next, consider whether or not it should be or needs to be hardcoded in the image or if you can simply apply that configuration change via Group Policy. Anything hardcoded will require you to come back and update and re-test, and re-release the image when the value needs to be changed, whereas a Group Policy setting is easily tweaked centrally.

Inevitably there are various tools, gadgets, trinkets, etc., which make troubleshooting easier. My experience is that a great many of these tools don’t require installation and will simply run from a network share. Rather than caching tools locally on each server, or installing individual copies, put them out on a share that you can access from any machine. This way you only need to refresh one location when a tool gets updated and you also aren’t installing essentially random software on servers on an as-necessary basis. As soon as those installs aren’t consistent across all servers, you start permuting your test matrix. Personally the only thing I consistently install on a server build is Netmon or Wireshark and occasionally BgInfo (Sysinternals).

Over the past couple years, readers have identified a number of mistakes that unfortunately made it through the edit cycles for Active Directory, 4th Ed. O’Reilly recently launched a process by which authors can make updates to the source files that they use to produce eBooks and print conventional paper books on demand. I took advantage of this a few weeks ago and I resolved all of the errata which were reported as well as a couple I found myself. Here’s the quick summary on where the updated text can be found:

Print Copies - If you’ve bought a print copy, you’ll need to look at the notes I made on the errata page. However, as O’Reilly is now doing print on demand for this title, the updates will trickle out into the supply chain over time and newly purchased books will be updated. Obviously this timeline is highly dependent on how much inventory is sitting in warehouses.

eBooks - If you bought any of the various eBook formats O’Reilly offers in their web store – PDF, mobi, and ePub – then you’ll be able to login to your account and pull an updated copy down. I’m told you will also be getting an email sometime soon (if it hasn’t gone out already) notifying you of this as well. If you purchased the book for Kindle from Amazon, Amazon doesn’t have a mechanism to push updated content to your Kindle, so you won’t get an update. This also applies if you bought the book for iPhone/iPad from the Apple bookstore. The iPhone/iPad “app” version of the book is also not going to get updated due to the shift to the native Apple Bookstore.

There was an unfortunate layout error in Active Directory, 4th Edition which caused the tables in Chapter 2 which explain group nesting to have the column headings over the wrong columns. This of course changes the meaning and makes the tables less than helpful. I’ve gone ahead and pasted the tables and captions below with the correct column headings.

I made a number of improvements to the website this weekend. The major change is that I moved from the in-box commenting in Graffiti to Disqus. I’ve been having issues with the comment system for a couple of months, and Disqus adds quite a bit of functionality. I was able to port over all of the comments with metadata intact, but, trackbacks and pingbacks are currently still going against the local database. I’ve tested in IE9 and Firefox 5/6, but, I haven’t validated other browsers. Let me know if there are any layout bugs or other issues.

For the curious, Release Notes:

Fixes

• Fixed CSS bugs causing all text to be highlighted on mouse-over in comment area
• Fixed HTML bug causing footer not to span complete page in some scenarios
• Fixed CSS bug causing highlighted code to be indented
• Removed favicon.ico from 1.3 upgrade
• Removed IE7 compatibility mode header
• Removed category level RSS autodiscovery publishing
• Changed Tag RSS autodiscovery publisher to include “Tag” in title
• Replaced checked binaries with release build files

 

New Functionality

• Replaced commenting infrastructure with Disqus
• Updated syntax highlighter to latest release
• Replaced PowerShell syntax highlighter brush with a better one from PoshCode site

The Exchange Online component of Office365 as well as Live@EDU exposes a variant of the Exchange Management Shell that you’d normally use if you were managing an on-premises Exchange 2010 organization. Connecting to it requires a few steps which are documented here. I’ve been pasting in the three commands one at a time now for months and it’s gotten rather annoying. A bit of research reveals that you can add custom PowerShell code that is available anytime you launch a shell by modifying your PowerShell profile. You can read more about the various profiles you can modify here, but, I decided to simply modify the one specific to my user account. To do this, open a new PowerShell window and run this command:

notepad $PROFILE

If you haven’t done this before, notepad will prompt you to create a new file. Plug this code in the resultant file:

function Connect-ExchangeOnline
{
  $LiveCred = Get-Credential
  $global:Session365 = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirection
  
  Import-PSSession $global:Session365
}

function Disconnect-ExchangeOnline
{
  Remove-PSSession $global:Session365
}

Save and restart PowerShell, and you’ll be able to run Connect-ExchangeOnline to connect to Exchange Online/Live@EDU in one easy step.

The VBScript below will collect a number of hardware demographics from machines and output them to a CSV file. These demographics include:

• Hostname
• Serial Number
• Make
• Model
• BIOS Version
• Operating System
• CPU
• Memory (MB)
• Disk Drives

You’ll need to supply an input file with one hostname or fqdn per line. You can configure the input and output files on lines 14 and 15 of the script.

In Part 1 we took at look at the architecture of the Quest Free/Busy (F/B) Connector in Coexistence Manager for Notes (CMN) as well as how Exchange interfaces with it. We also configured the F/B Connector web services and the Domino Free Busy Connector Service. In Part 2, we configured the Exchange Free Busy Connector Service, the Domino QCALCON task, and the Exchange organization. In this post, we’ll complete the configuration by configuring Lotus Notes as well as building a test user in Exchange and Lotus Notes to validate the configuration. At the end of this post you should have working Free/Busy coexistence between Exchange and Notes.

As a reminder, here’s a copy of our sample environment that will be referenced:

Configuring the Lotus Notes Domain

All of the configuration tasks in this section will be performed in the Domino Administrator tool.

1. Browse to Configuration > Messaging > Domains.
2. Select Add Domain on the toolbar.
3. Populate the Basics tab with the following data:
• Domain type: Foreign Domain
• Foreign domain name: Exchange

4. Populate the Mail Information tab with the following data:
• Gateway server name: LN-ADM01/CONTOSO.
• Gateway mail file name: mail.box.

5. Populate the Calendar Information tab with the following data:
• Calendar system name: LN-ADM01/CONTOSO.
• Calendar system: mail.box.

6. Click Save & Close.

At this point, Domino should begin routing Exchange calendar requests to the QCALCON task and over to Exchange. To test this, we’ll need to configure a couple test users.

Testing the Configuration

We’ll create two test users for this exercise. User George Washington will have mail on Lotus Notes, while user Abraham Lincoln will have mail on Exchange. First, let’s configure Exchange.

1. Create a Contact in Exchange for George Washington. Specify an External Email Address (targetAddress) of gwashington@lotus.contoso.com.
2. Create a Mailbox in Exchange for Abraham Lincoln. Ensure the primary email address for Abraham Lincoln is alincoln@contoso.com.

In step 1, we’ve created an object which will be used for routing mail as well as for ensuring that the availability service redirects free/busy information to the Quest components. Next, let’s add these users to Lotus Notes.

1. Switch to the People & Groups tab in Domino Administrator.
2. Browse to Domino Directories > CONTOSO’s Directory > People.
3. Click Add Person.
4. Populate the Basics tab as shown below:

5. Populate the Miscellaneous tab as shown:

6. Click Save & Close.

Next, we need to register George Washington with Notes.

1. In People & Groups, expand People on the right under Tools, and click Register….
2. Populate the Basics tab as shown. Be sure to select LN-SRV01 by clicking Registration Server….

3. Check Advanced in the lower left
4. Switch to the Address tab.
5. Populate the Address tab as shown:

6. Click Register.
7. Press F9 to refresh the People view.

What we’ve done is created a Person document for Abraham Lincoln which forward to Exchange and specifies the Foreign Domain created earlier for calendaring. We’ve also created a full fledged mailbox enabled user for George Washington in Lotus Notes.

Testing

Populate Abraham Lincoln’s calendar with a few appointments in Exchange. In Lotus Notes, populate George Washington’s calendar with a few appointments as well.

1. Open George Washington’s person document from the People view in the NAB.
2. Click Open Mail File… on the toolbar.
3. Click Mail and then Switch to Calendar in the upper left of George Washington’s mail file to open the calendar.
4. Create a few appointments.

In Exchange, invite George Washington to a meeting using Outlook. Verify the free/busy information is displayed (e.g. no hash marks). In Lotus Notes, invite Abraham Lincoln to a meeting. verify that the Find Available Times tab shows free/busy information. Be advised that in both cases it may take a few moments for data to become available.

Troubleshooting

There are a number of places you can look to for troubleshooting information depending on where you think the problem lies. All of the Quest components log useful information to a file:

• QCALCON (Domino to Exchange lookups) – c:\lotus\domino\qcalcon.exe.log.
• Exchange Free/Busy Connector Service (Domino to Exchange lookups) – C:\Program Files (x86)\Quest Software\Quest Coexistence Manager for Notes\Free Busy Connector\ExchangeFreeBusyService.exe.log.
• Domino Free/Busy Connector Service (Exchange to Domino lookups) – C:\Program Files (x86)\Quest Software\Quest Coexistence Manager for Notes\Free Busy Connector\DominoFreeBusyService.exe.log.

One additional useful tip surrounding the Quest components deals with caching. Both components keep requests cached in memory for 5 minutes by default. When you're troubleshooting, this can be problematic as you must restart the service each time you change a user in Notes or Exchange to see the effect. You can go in the Advanced configuration of either service in PowerGUI and tweak the cache lifetimes to "0" to disable caching. Just be sure to return the cache to the default values once you put the environment in production.

The Outlook availability service logging is also quite useful. You can enable that by going to Options>Advanced>Other>Enable Troubleshooting Logging. Restart Outlook and create a new meeting request. You’ll find logging information in %temp%\olkas which will include the exact errors and XML returned by the Quest components.
