I'll be proctoring the "Configuring Configuration Manager 2007 Security including PKI" labs this coming Wednesday. I'll be at both the 1:15PM and 3:00PM sessions. I'll do a write-up here afterward going over some of the common problems that were brought up during the labs and will try to provide some solutions. Chances are if someone's hitting them in the lab, there will be people running into them in the "real world." If you're attending either of those sessions, feel free to come and say hi to me. :)
