I installed the ITMU the other day and deployed the upgraded SMS advanced client to all my client's workstations. The install went very well (after a major issue) and we have good reports. I had intended to work with the other Brian Tucker here on myITforum for documentation / notes from the field, but due to several client obligations he was unable to lend a hand. I have finished the documentation and also created a blogcast which shows what you get after the ITMU installation and some of the things you have to do yourself. The documentation is only 14 pages (9 are related to the Microsoft Webcast Q&A) and gives step by step instructions on how I setup the ITMU. Not only do I list the steps, I give the names I gave my new collections (along with the SQL queries), information on the issues I ran into, log files to check, links to related Microsoft documentation and also lists all the questions asked during the Microsoft Webcast last Friday. Chris Mosby and I both had the same idea during the webcast!
The blogcast is finished, but I want to think about it for a day and make sure it shows everything I want to explain. As for the documentation, you will have to wait for it to be published on myITforum. I will submit it in the next day or so, but I have to wait my turn for it to be published. Unless of course Rod wants to help me out and post it quick......
