Well I'm still working on the 2007 install. I will be installing Communicator shortly to incorporate some of the cool features.
In the meantime all kinds of emergencies today. The main one was a virus outbreak at a client who still uses Symantec for AV. We tried to talk them out of it but oh well. A quick way to find out which computer is infected is to go into the firewall. In this case it's a Cisco ASA. From there you can do a show connection protocol tcp port 25. This will show you every computer that's trying to connect by blasting out email. I ignored the server and spam filter and found the one workstation that was infected fairly quickly. I then dispatched a tech and he is cleaning it up.
