My URL is changing (ever-so slightly)

Hi All,

Just a heads up to any returning readers out there. I have decided to change my URL. (its a small change). Here are the new details:
New URL:
http://ivan.dretvic.com

Old URL:
http://ivan.dretvich.com – the trailing ‘h’ has been dropped.

They will both work but hyperlinks will now default to the new one.
RSS should still work as well.

If anyone has any problems with this change please let me know so I can rectify it.

Regards,
Ivan

Adobe have come to the mercy of IT administrators by introducing an auto updating feature for Flash Player. This is excellent news but now we need to get it to work in the real world

Exchange 2010 test scripts

This is a scribble of items that I feel I should test and may hopefully help others when they do their testing. I will be updating this post when do come up with additional tests – and potentially some PS scripts as well that help in the testing. Read more »

Upgrade Exchange 2010 SP1 to SP2 on a single server environment

I have read a number of documents online regarding the installation of Exchange 2010 SP2 where most are quite comprehensive however they lack in clear explanation of what to do in a single server environment. Below are the steps I used to install Exchange 2010 SP2 on an Exchange 2010 SP1 UR4 single server environment that also had Forefront for Exchange installed.

Before we begin I must say this entire setup process is using the Command Line Interface. Its a very basic setup so don’t be scared of doing things using the command line. Read more »

How to clear old unused distribution lists from Exchange 2010 programatically

If you are an Exchange administrator you would most likely have hundreds of distribution lists in your organisation and no idea which ones are being used. Well I had this problem and decided to do something about it. I set out to see who was actually using these DL’s and remove all the ones that have not been used in months. I will be looking at Static DL’s. If you use Dynamic DL’s then the concept will be the same however some of the syntax may differ slightly.

High level overview of steps

Here are the steps I went through on a high level to identify and remove unused Distribution Lists in my Exchange 2010 SP1 environment:

  1. Increase Exchange MessageTrackingLogs from the default of 30 days to 90 days
  2. Export list of ALL distribution lists
  3. Export list of ALL active distribution lists based off Exchange Tracking Logs
  4. Compare the results and output the inactive DL’s
  5. Hide all unused DL’s from the GAL
  6. Delete all unused DL’s from Exchange
