No, not the Big O’s hit (if you don’t know who the Big O is, ask your parents <g>), but the dreaded:
Hmmm, lost/corrupted/hosed the secure channel. What next? I know, logon locally, take the computer out of the domain, put it into a workgroup, then restart, rejoin the domain, restart yet again; all is sweet! Nope, bzzzzt! Fail. It looks like it has worked, but what you have most probably done in the background is destroyed the original SID (Security IDentifier) of the computer and created a new computer object in the domain; all group memberships, ou membership, SCCM 2012 object history … gone!
The more correct way? Read on. First, go to your Admin tools; either ADUC (Active Directory Users and Computers) or ADAC (Active Directory Admin Center – new from Windows Server 2008R2 on), right-click the offending Computer object and Reset Account! This sets the computer password to computername$ and allows the computer to reset that password when the secure channel is restored. Next, logon locally:
Then, open an Administrative PowerShell prompt:
Uh oh … more red hints, I see lots of these, deliberate errors I tell my students (well, that’s what my old sergeant said in the Army!). Lets try that using the correct command:
That’s better! Supply the correct credentials, and:
The returned value is Boolean, True means all is working, we’ve rejoined the domain and have preserved the SID, the object history in SCCM and all is sweet, until next time.
If you want to do this remotely (certainly saves walking, or in the worst case, driving to the workstation, refer to this TechNet tip: http://technet.microsoft.com/en-us/magazine/ff700227.aspx

Import-Module ConfigurationManager ? Nope, won’t work, at least not without jumping through a few hoops. Looking at the helpful red hints (I get lots of these!), the module is not found in the default path.
From a PowerShell prompt, you need to change to the ….\bin directory, then import a .psd1. Using the -verbose shows the import progress, much better than staring at a screen, wondering what’s happening in the background 🙂
Ready to go? Not quite. As you can see, we must now connect to the drive that represents the site, in this case, S01.
Last thing to do, update the help file:
PS SO1:\>update-help -module configurationmanager
Adding the -module makes sure I only update the cm module, not all modules.
Now we can start using the new Cmdlts. Not too hard, just a bit fiddly. Good luck with the more than 470 cmdlts available.
Oh, and don’t forget, you need PowerShell 3.0 (or above) and the SCCM 2012 R2 console installed on the machine as well. Time for you to play!

That bit of “text speak” should have translated to “Are You Ready For R2?” in your own mind, hopefully it did! R2 means the second release of Windows Server 2012 and it will a huge impact on those looking at Certification on Microsoft products. If you are currently studying for a Microsoft Certified Solutions Associate (MCSA) in Windows Server 2012 then you’ll need to read this post and be prepared to add some additional items to your study list.
Effective January 28th 2014, the following exams contain R2 content:
