HOTFIX is available for the "Operating System Deployment" feature of System Center 2012 R2 Configuration Manager

7:16 am in CM12 R2, OSD, PXE, sccm 2012 R2 by Kenny Buntinx [MVP]

 

All,

KB 2905002 has been posted to the hotfix servers to address two post-R2 issues:

This update resolves the following issues in Microsoft System Center 2012 R2 Configuration Manager.

Issue 1

After you enable the PXE Service Point role

(http://msdn.microsoft.com/en-us/library/jj217832.aspx)

on an instance of a specific distribution point, or you select the Deploy this boot image from the PXE-enabled distribution point property of a boot image, the Windows Deployment Service (WDS) stops running. Additionally, entries that resemble the following are logged in the Windows Application log:

Note This problem affects only distribution points that are installed on site servers.

Issue 2

When operating system image files are downloaded to Configuration Manager 2012 R2 clients, you may find that the download takes longer than it did in previous versions of Configuration Manager 2012 clients. You may see this behavior when the target client is running Windows PE or a full Windows operating system.

Hope it Helps ,

Multicast-enabled Distribution Points Stop Working after Upgrading to System Center 2012 R2 Configuration Manager

11:23 am in CM12, CM12 R2, ConfigMgr 2012, configmgr 2012 R2, ConfigMgr 2012 SP1, multicast, R2 by Kenny Buntinx [MVP]

 

If you upgrade your hierarchy  to System Center 2012 R2 Configuration Manager and you have distribution points that are enabled for multicast stop working, look for entries similar to the following in the mcsexec.log: Error finding namespace: 0xc1210106

Make sure that before you upgrade the site or hierarchy, to make sure that Cumulative Update 3 or later is installed.

However, if you have already upgraded the site to System Center 2012 R2 Configuration Manager and multicast is not working on distribution points, perform the following procedure on each distribution point that is enabled for multicast:

  1. Edit the properties of the distribution point, and click the Multicast tab.
  2. Clear the Enable multicast to simultaneously send data to multiple clients option, and click Apply.
  3. Wait for the multicast configuration to be removed from the distribution point. You can verify removal by checking the MCSSetup.log file.
  4. Select the Enable multicast to simultaneously send data to multiple clients option, and click OK.
  5. Wait for at least one hour to make sure that Hierarchy Manager has reinstalled the multicast server.

Hope it Helps ,

Configuration Manager 2012 SP1 and R2 : Send Ctrl-Alt-Del remotely is randomly not working in Remote Tools

7:15 pm in CM12 R2, ConfigMgr 2012, configmgr 2012 R2, ConfigMgr 2012 SP1, Remote, Remote Tools, tools by Kenny Buntinx [MVP]

 

Earlier this week, A customer of mine was trying to use the Remote Tools feature. Fancy feature , except that the helpdesk has connected to a computer via Remote Tools, chosen Ctrl-Alt-Del from the drop down menu, and nothing happens remotely. No problems on XP machines , but on some remote Windows 7 and windows 8 machines it would work and on others it won’t .

Before going deeper , I checked the following settings :

  • The workstation was in a “Logged Off” state.
  • Default Client policy is set to request permission to connect.
  • The user has the permission to use and take over the remote machines.

Again, this is a random occurrence.The worst that can happen and the logs look green like a golf court Smile with tongue out

Solution :

It took me a while figuring this out , but finally found the root cause . It was a group policy preventing doing this kind of stuff .

There is a group policy option for this simulation of keys… Look under Computer policies -> Admin Templates -> Windows Components / Windows Logon Options and then  set “Disable or enable software secure attention sequence” to ‘enabled’  You must then change “Set which software is allowed to generate the secure attention sequence”  to “Services and Ease of Access applications”.
