Computer Group Membership Change Without Rebooting
I was working with a client this week where we had a need to create a special Group Policy Object for a pilot scenario. This GPO needed to be filtered to only apply if the computer was a member of an AD Security Group. We could add the machines into the group, but we needed to not be forced to reboot all of the machines in order for the group membership to be effective. After doing a bit of searching I found out how to do this…use the “klist” command. This is native to Windows 7 and Windows 8…and to Server 2008 and later. It is not included in Vista…and I’m not sure about Windows XP (but you should be looking at getting off of XP anyway!). The command to trigger this is:
klist –li 0x3e7 purge
Klist with the purge switch forces the computer to refresh the Kerberos tokens…which also effectively recognizes the group membership changes. The “0x3e7” is the part of the logon id that identifies the computer account (Local System).
Top 20 Sessions of MMS 2013
I knew that the Microsoft Management Summit was going to be very busy this year…especially after getting three breakout sessions and one “birds of a feather” session on my speaking schedule. (I’m still honored to be asked to speak at all…much less to speak multiple times.) I dramatically underestimated the level of exhaustion that would result from that schedule! I was very surprised to see the results of the session evals after the conference ended. My unspoken goal was to have a session ranked in the top ten for the event…I hadn’t even mentioned that goal to my wife. Even with that goal in mind I was still very surprised to see the eval results at the end…to have the highest rated session of the event! I’m still in shock…and very excited! One of my other sessions is also tied for 12th for the event!
I know all of the speakers would join me in thanking the attendees for taking the time to rate the sessions. We appreciate the feedback…and that data is part of what Microsoft uses to determine who is invited to speak again. Below are the top 20 sessions for the event based on the average of the “overall satisfaction” question. One other interesting note when you look at the top 20…how many times you see Johan listed. Six out of his seven sessions were in the top 20…including half of the top 10! Wow!
All of the sessions from MMS are available on Channel 9, and I’ve included direct links to the top 20 below.
