    Sometimes it’s necessary to figure out which Global Catalog (GC) your Exchange 2010 is using. Open EMC Go to Server Configuration, right-click each server and choose Properties and go to System Settings tab. You can also look for Event ID Event ID 2080 in the Application logfile and KB316300 gives you an idea what this means.

  • Evoko_Room_Manager1

    This has to be one of the coolest thing I’ve tested in my lab, the Evoko Room Manager. It’s a flat screen that you put on the wall next to your conference rooms and it will show you the room’s schedule and also enable users to change/add/end meetings – in a very nice design. The frame is either green if the room is green and red if it’s occupied. There are plenty of user guides available, other reviews available and [...]

  • I’ve come across quite a few Exchange migrations lately during mergers and acquisitions where the source domain had a bunch of users and instead of using ADMT (Active Directory Migration Tool) to migrate the user with SIDHistory they simply just manually created all the users in the destination domain (without mailboxes) and started using them. Then a few months down the road they start to think of how to migrate Exchange and the mailboxes. Well, since SIDHistory was not migrated [...]

This company also had gone through many changes so we had to verify that each accepted domain had the correct MX record specified on the DNS. The external domains were hosted on external DNS:es and the mailgateways were 3rd party. So instead of manually [...]

Nexa_PB-3

Maybe you’ve read the description of my home entertainment network. Some of you wanted to know how I configured the remote control thing. In part 1 I showed you how to remote control IR devices using iPhone running OpenRemote and Global Cache  iTach WF2IR. After this guide you will be able to switch on/off a lamp using your iPhone/Android. For this to work, I bought myself the Nexa PB-3 package (~$30)which enables you to switch on/off using the remote control [...]
