Enhancing your presentations

I stumbled across this link when looking for something entirely different, and picked up some good hints and tips about presenting effectively.  i thought I’d share it with you in case you’re the sort of person who has fear in your heart if you’re asked to stand up and present…

10 tips to enhance presentations

To better engage your audience, follow leading communications consultant Cliff Atkinson’s savvy tips for enhancing your presentation. Learn ways to interact with your audience so that your presentation is less of a lecture and more of a dialogue. Remove distractions that lessen the impact of your story, such as too many special effects in your slides, or equipment problems in your meeting room. Instead of all that glitz, learn innovative methods for focusing your ideas, coordinating spoken words with slide images, and creating an engaging narration.

And if you’re an expert presenter….. do you want to share some tips?

Filtering contacts from the GAL

 John mailed me with this conundrum:

We have a dozen or so contacts that we do not want displayed in the GAL. Instead, we use a secure custom address list to display these contacts. I cannot figure out how to change the filter on the default address lists in Exchange 2000/2003. In ESM, the modify button is greyed-out on the default address lists like “All Contacts” and the GAL. So I used ADSI Edit to modify the PurportedSearch attribute on the default address lists. This seems to work after running the RUS, but eventually the filter stops working and the default filter is applied again — even though my filter changes remain in AD. I go to ESM and run preview and the filter mod still works. But in Outlook, it doesn’t work. Where do I need to make this change so that it will stick?

Well …the generally ‘recommended’ approach would be to create a new GAL with the filter you want and then deny access to the default GAL.

You could:

1) Create a new GAL and use appropriate filter. Never touch ADSIEdit for these tasks.
2) Assign permissions. First, test; use individual user account of a test mailbox and a) deny access to default GAL b) grant access to the new GAL. If all goes well, deny everyone access to default GAL.

Trick here is to understand that Outlook will, among those it has permissions to, attach to the GAL that has the most number of items in it. Because default GAL typically has the most items in it, it’s imperative that they deny access to it.

Lastly, never delete default GAL object.

LCS 2005 Service pack 1

I was wondering why I couldn’t send a URL to my colleague the other day and thought that it was just a policy that we’d introduced internally.  Then I remembered that this was a new feature for LCS 2005 which is designed to stop the propagation of IM virii.

SP1has lots of useful extras like this.  You can download it here

Microsoft Office Live Communications Server 2005 with SP1 further improves business efficiencies by enabling information workers to communicate and share presence information with contacts in real time through a security-enhanced, enterprise-grade, integrated environment.

Live Communications Server 2005 SP1 improves on the features of Live Communications Server 2005 by extending the federation model, enhancing functionality, increasing security, and improving performance and infrastructure support. These improvements include:

  • Tools to enable Public IM Connectivity; the ability to add contacts, send instant messages, and share presence information with users of the three main public IM service providers MSN, AOL and Yahoo!.
  • Enhanced federation, which uses DNS-SRV resolution to simplify connecting to federation partners.
  • New optional spim filters for better control of unsolicited instant messages.
  • Support Microsoft Office Communicator 2005.
  • Support for multiple tree Active Directory forests.
  • Improved server API performance.

How to create Exchange folders with a script

I’ve found a web page which is quite useful if you have to create numerous folders in Exchange and would prefer to script the creation of the folder.  The Exchange SDK has quite a few scripts starting at this page that will give you a start.  The creating folders scripts are here.

Useful if you have a distributed organisation with similar folder heirarchy requirements.

LCS 2005 concurrent session limit

I often talk about LCS 2005 and how many more concurrent sessions we can support compared to LCS 2003.  We’ve greatly increased from the previous figures of 10,000 active sessions.  So when I was asked to quantify what I meant with Active concurent sessions after a previous blog entry.

Its important to distinguish between concurrent connections and concurrent sessions.  LCS standard and Enterprise edition can cope with up to about 25,000 concurrent connections.  This is limited by the type of hardware you’re using and the amount of processing power you have available.  To get beyond this, you need to scale out by adding servers, load balancing and creating user pools.  Then you can get to the million mark that we talk about during presentations.

Concurrent sessions are different.  They’re not really determined by the server, rather by the amount of active chats / audio / video / sharing activities that are actively going on at the time.  So this has an impact on your bandwidth and ultimately the message rate impacts the maximum number of sessions.  Here, you can use the capacity planning toolkit  and the resource kit to help you plan accordingly…
