I was looking for a good reference of AD and Exchange schema version numbers yesterday and thought it would be handy to combine all the bits of information I came across into a single post.

There are a couple of ways to find the schema version number, I prefer using “DSQuery” to “ADSIEdit” so I’ll be making use of “DSQuery” in the following examples.

To determine the version of your AD schema, we use “DSQuery” to find the value of the “objectVersion” attribute:

dsquery * cn=schema,cn=configuration,dc=yourdomain,dc=local -scope base –attr objectVersion

Here is a mapping between the “objectVersion” attribute value and the AD schema version:

To determine the version of your Exchange schema, we use “DSQuery” to find the value of the “rangeUpper” attribute:

dsquery * CN=ms-Exch-Schema-Version-Pt,cn=schema,cn=configuration,dc=yourdomain,dc=local -scope base –attr rangeUpper

Here is a mapping between the “rangeUpper” attribute value and the Exchange schema version:

NOTE: in both examples, it is assumed that your domain name is “youdomain.local”

Having attended Tech-ed Australia last week, I cant help but echo my friend and colleague Craig’s thoughts. Infact, I thought I would repost something from his blog. The original post can be viewed here

Last week I attended TechEd Australia in the Gold Coast.  I had a great time learning, connecting, talking, networking, teaching, socialising and presenting.  Having said that I left the Gold Coast both drained and a bit frustrated.

While there was a lot of content there, there was an awful lot of content that was not there.  I was lucky to be one of the speakers in the UC track.  There were 12 sessions allocated for the UC track.  Nine were focused on Exchange 2010 and three went to OCS 2007 R2.  Now, granted, Exchange is a flagship product and 2010 is an exciting release.  I would not take anything away from Exchange.  But OCS 2007 R2 needed much more coverage.  Rewind a year to TechEd 2007 and all the OCS 2007 R2 content was still under embargo so the result of the lack of sessions at TechEd 2009 is that R2 content has not really had a good airing at a large public conference in Australia.

This is not due to a lack of speakers – I submitted two other sessions that did not make the cut.  I know other external speakers who put sessions forward that did not get a slot at all.  I know the Microsoft UC guys could of done more sessions.  Nor is it due to a lack of things to talk about.  In pulling together content for our overview session Derrick Buckley and I drew content and inspiration from no fewer that 5 TechEd US sessions!  Oh the detail we could of gone into if we had had the time.  Edge Services, Conferencing Solutions, Group Chat Architecture and UC Applications could all easily be sessions in their own right.

So if we need more room in the UC track (among others) and we can’t trim back on the existing content because we need that too, what’s the solution.  Simple really.  TechEd Australia should be five days long, like the one in the US is.

Now, I know that events cost money and extending TechEd Australia to five days would not come cheap – but there must be a way.  One suggestion I would put forward would be to combine TechEd Australia and TechEd  New Zealand into one ANZ event.  Surely it would be cheaper to run one event for 4000-5000 people than two for 2500 each.  Also with fewer flights and nights of accommodation for the US speakers that hit Australia and New Zealand perhaps we could get more US speakers out here for the same money?  More days, more colleagues, more experts and more content.  It sounds like a winner to me.

Now – in reality this would probably mean canning TechEd NZ and just having one in Australia since there are no venues in NZ big enough to host an event that size.  I use to live in NZ and I would of crossed the Tasman to attend TechEd in Australia if need be, but I’m sure there will be plenty of naysayers.  Even now, if NZ builds a venue I would happily cross the ditch in the other direction to attend an ANZ TechEd in New Zealand.

I tweeted this thought the other day and got a few comments back from people who thought two more days would be great if their livers could hold out.  What say you Microsoft?

Today I attended the SEC208 session with Jamie Sharp which really provided a great overview of Microsoft Forefront Threat Management Gateway (TMG). If you use and like ISA server, you’ll love TMG.

Some of the great new things we can look forward to are web filtering, URL filtering and it also has built in Exchange Edge Server functionality which means if you have an Exchange Edge Server role deployed and also use ISA server, you can now consolidate these into a single server. Another cool thing is, like Exchange Server 2010, TMG will only be available in 64bit.

TMG is currently available as beta3, click here to download it. It is expected to be RTM towards the end of the year.

If you are attending tech-ed, make sure you get your Business Productivity Online Suite (BPOS) account setup.. I have been most impressed by BPOS.

So you’ve arrived in the Gold Coast, checked in, unpacked, visited the gym and checked out the pool (right?) now what? I was planning which sessions to attend over the next few days and thought it would be a good idea write a post about it.

Firstly, I would definitely recommend that you get to registration as soon as possible to avoid the rush! Registration will be open until 9pm tonight and then again from 7am tomorrow morning. Once registered you can also pick up your HP Mini Notebook (of course I am writing this post on it!), there is an “unpacking area” in the convention centre if you would like to dispose of the box and packaging.

There is a welcome reception at the exhibition hall betweenn 6pm and 9pm and the opening keynote is tomorrow at 08:15am. All this info is in the mini-guide.

As far as sessions go, here are some of the ones I am looking forward to attending:

Wednesday:

09:45am – 11:00am UNC201 – Introduction to Exchange 2010 with Johann Kruse and Roger Lawrence

11:30am – 12:45pm UNC302 – Exchange 2010 Architecture with Scott Schnoll

Thursday:

08:15am – 09:30am UNC305 – Exchange 2010 Voicemail with Mario D’Silva

5:00pm – 6:15pm UNC309 – OCS 2007 R2: Overview & Architecture with Derrick Buckley and Craig Pringle

Friday:

08:15am – 09:30am SEC310 – IAG… the success story with Jean-Pierre Simonis

11:30am – 12:45pm – UNC311 – Telephony in OCS R2 with Brendan Carius and John Smith

There are of course other events going on, one of which is Sydney UC and Melbourne OCS User Group get together on Thursday. click here for more info

Cant make it to tech-ed this year? no need for tears… many sessions are available on live meeting, click here for more info

and finally, yes, of course I will be tweeting all week! be sure to follow me on twitter!
