imageTo follow up on previous life cycle post I’d like to blog a bit on a very interesting issue that has already been acknowledged by Microsoft but yet to be officially documented (in Microsoft public knowledge base).

There is an issue that has been occurring with multiple connections to the same Exchange 2010 mailbox from XP SP3 machines using NTLM authentication.
The problem manifested itself with inability to connect more than 1 client at a time. If users left their Outlook connected to Exchange 2010 mailbox at the office then home connection would fail.

Initially, the workaround found empirically was to set all but one of the Outlook clients to connect using basic authentication. The problem that eventually came up with this workaround is that if the user has opted to allow autodiscover to change the connection settings without prompting them again, the basic authentication setting will be reverted to NTLM each time they restart Outlook.

Upon investigation with Microsoft, it was discovered that the problem only seems to exist when the different machines are connecting to multiple CAS servers, but it cannot be reproduced when connecting to the same CAS server (with all clients connecting via NTLM).

Apparently the resolution until the permanent fix is available may include editing of hosts file to make a machine explicitly connect to a specific CAS server. 
The downside to this solution is that if anything happens to the CAS server that someone puts in their hosts file, they will have the potential to lose connectivity to their mailbox.

Apart from that there is another possible workaround that can be implemented (if certain things are in a particular environment):
It is possible to add an A record for the VIP instead of using a hosts file (given Active Directory DNS is used for workstations). Thus internally all machines will use the DNS from Active Directory as an override.
This has not been tested actually but I can’t see anything that may prevent the configuration for seamless work at this time.

There is also a chance the problem will never be resolved by Microsoft as Windows XP has reached EOL for the most part and there shouldn’t be any surprise if that ends up with something like ‘please upgrade your workstations’smile_regular

I’ve been taking part in a number of migrations from both on-premise installations and hosted solutions to the cloud in recent years.

It was pretty peculiar to find out how many folks around are still using legacy systems (from the standpoint of those who daily deal with cutting edge technology of course) like Exchange 2000 or even some POP servers with really limited functionality to say the least.

To strengthen my amusement was the fact that the most conservative businesses are the big organizations having access to bigger financial resources than SMBs. It is a kind of of ‘set it and forget it’ approach that, however, has its reasoning. Migration from such installations with hundreds of users actively using their emails usually takes at least a month an rarely turns to be completely painless. Moreover, many are skeptical to touch systems that ‘work’ and a bunch of new features and possibilities current messaging systems provide do not look very seducing under such circumstances.

And here comes product lifecycle that often becomes a change driver.

Just a few months still remaining before the extended support ends for Exchange 2000 (not Conferencing server) that would inevitably mean certain difficulties for those maintaining in-house installations.

Exchange 2003 that is a flagship for most on-premise installations (yes, the number of Exchange 2007 installations is significantly smaller!) maintains its positions and will likely fall only to Exchange 2010 serving as another accelerator for a change.

These business if they prepare for the move will prepare moving to Exchange 2010 skipping Exchange 2007 due to not only a richer set of new features but also because of lower TCO and higher reliability.

Exchange 2007 is not going to retire soon apparently. However, some complexities involved in its deployment and some technology tremendously improved in Exchange 2010 (like storage design for example) do position the latter as a market leader and obvious market driver for years to come.

Having invested in Exchange 2010 the businesses may feel safe and quiet for a decade ahead:

Another trend worth mentioning is that more and more big organizations start outsourcing their messaging infrastructure to the cloud after they realize the cloud has become a reliable place for keeping sensitive data providing higher levels of safety, redundancy, reliability, support than many on-premise implementations. Lower TCO adds more value too.

Nice trend and I’m excited to see how the messaging evolves from mostly on-premise installations to the cloud based feature rich solutions benefitting businesses around the globe.

Exchange rocks!

 

Been wandering through Microsoft Partner Portal, specifically Partner Learning Center and found an awesome course available for partners that will be really interesting to every Exchange PRO –

This turned out to be a very good course on Exchange 2010 that is highly recommended even to those having all these books in possessionsmile_regular. I’ve read most of them but such courses are always of a big value and do provide concise and in-depth overview of the product.

The course consists of the following topics:

  • Introduction to Exchange 2010
  • Introduction to Exchange 2010: Presentation
  • Setup, Deployment, and Server Role Configuration
  • Setup, Deployment, and Server Role Configuration: Presentation
  • Exchange 2010 Setup, Deployment, and Server Role Configuration: Lab

The labs available in the course add an extra value to the course and the course itself may serve as preparation material for Exchange 2010 certification.

There can be a problem searching for this course. I tried this way and it worked. First off, you’ll need to go to Partner’s Learning Center –

https://training.partner.microsoft.com/learning/app/management/LMS_LearnerHome.aspx

Then you’ll need to search the catalog by keyword ‘exchange ignite’ and this would yield that hidden gemsmile_regular

Happy learnin’!

 

Here it comes! All Exchange Pros around have long been anticipating this release and now it is RTM.

Most of the features of SP1 were described earlier, and Microsoft released a beta of the mail server’s service pack in June at its Tech-Ed event in New Orleans. This first service pack features improved e-discovery and e-mail management capabilities for IT pros. Those capabilities are enabled, in large part, because Exchange 2010 uses a new “Exchange archive” approach for e-mail storage that differs from the traditional .PST storage approach.

The feature list and additional details are available here -

Technet

This is really excited and I’m looking forward to see it rolling out into the production environment soon.

SP1 for Exchange 2010 can be retrieved via the Microsoft Download Center here (a 522 MB download).

Happy installation/upgrade, Exchange Bros!

 

I’ve been dealing with cutting edge technology for sometime and once in a while every IT PRO has to decide where the career should go when some milestones have been reached, some solid knowledge obtained and the desire to set spurs to further development is still high.

Being primarily Microsoft Exchange professional I do love the product a lot but begin to feel the desire to extend the knowledge to areas that are adjacent to technology world. That being said, I laid my eyes on ITIL certification as this is something I expect to develop in a few coming years with relevant hands-on experience that has already been earned and will be earned in the future.

ITIL gives detailed descriptions of a number of important IT practices and provides comprehensive checklists, tasks and procedures that any IT organization can tailor to its needs. ITIL is published in a series of books, each of which covers an IT management topic. The names ITIL and IT Infrastructure Library are registered trademarks of the United Kingdom’s Office of Government Commerce (OGC).

This is how Wikipedia puts it. The reality is way more brutal – this is series of very valuable bits of knowledge that can be received not only with books but along with practical experience only. Followed by foundation level are professional exams one allowed to pass only after studying at certified course provider venues.

The chart displays the path to Expert is not easy at all and involves studying a lot of materials designed to accompany your foundation level of knowledge, practical experience with scientific approach and solid research basis.

Core Reference Material Includes

The ITIL Lifecycle Publication Suite - containing Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement – offers considerable costs saving against purchasing all five titles individually.

The books are pricey but the information they provide is really good and cannot be compensated by something else. So if you’re on the track you can’t avoid them:)

EXIN’s site (the organization in charge for this certification) outlines the following benefits of ITIL certification –

Why Certify?

EXIN’s certification does:
•    Strengthens your skills and maximize results.
•    Qualifies you for jobs that require specialized knowledge.
•    Optimizes your career opportunities.
•    Ensures you recognition from the industry and your peers.

I am going to take the challenge both due to professional necessity and internal desire to learn that I’m junkie of:)

By the end of the year I plan to pass Foundation exam –

The Foundation training in IT Service Management according to ISO/IEC 20000 provides professionals in ITSM a basic level of knowledge and understanding of both IT Service Management and Service Quality Management. The training is based on an introduction and overview of the main principles, concepts and relationships in the field together with a basic knowledge of the ISO/IEC 20000 standard and the terminology of the quality approach to IT Service Management.

And after that the plans are to take a course at some accredited center to become eligible for professional series exams. The sweetest plan is to take this course somewhere in Northern Europe during the trip with my family – I’d love to spend a few days on study either in Denmark or Norway while traveling there that I expect to repeat next summer:)

Alright, now it’s time to buckle down to make these plans a reality!
