[FIXED] Dism Error: 0xc1420117

I was getting the error message “Error: 0xc1420117” when I tried unmounting a wim file.

To give you a little background about my machine…

It’s is a Windows 2012R2 server with WDS, MDT installed. I installed MDT I needed to install Microsoft ADT which also includes Dism.

If you open a command and run dism the program just runs.

After a little bit of fooling around, I noticed the system had TONS of dism files on it. To resolve the issue you need to run the most up-to-date version. A way to check which dism files are on your computer is to open a command prompt and type:

  • dir C:\dism.exe /s /a

The output will look similar. Notice how the file in the C:\deploymentShare\Servicing\x64 has the most recent file where as the Windows\System32 dism file was made back in 2014.

dism-001

Using the most recent version of dism I then ran the commands:

  • dism /Cleanup-Mountpoints
  • dism /unmount-wim /mountdir:C:\dismmount /discard

NOTE – My mount drive is “C:\Dismount”

Hopefully, this will help you successfully fix your Dism Error: 0xc1420117

How to fix 8007071a -The remote procedure call was cancelled

Are you getting the error code “8007071a -The remote procedure call was cancelled” when you try and force group policy updates to machines?

8007071a-01

The reason why this is most likely happening is due to the firewall. It is blocking your ability to do this remotely. To allow you to remotely force a gpupdate there are a few services that you need to allow through the firewall.

I would recommend that you do this also through Group Policy! Here are the items you need to open up on the firewall:

  • Remote Scheduled Tasks Management (RPC)
  • Remote Scheduled Tasks Management (RPC-EPMAP)
  • Windows Management Instrumentation (WMI-In)

8007071a-02

 

Apply this to the OU at or above where you are trying to force the update. You now need to tell the person to reboot or open a command prompt and type “gpupdate /force”.

Doing one of those two things will allow you to right click an OU and force update going forward.

8007071a-03

You should now see that the computer will pass the update!

Upgrading Windows 2008R2 DC to Windows 2012R2

When you try to upgrade a Windows 2008R2 Dc to Windows 2012R2 you will notice that you most likely can’t.

Depending on your setup you will most likely get one or two of these errors.

  1. System Devices: Microsoft Emulated S3 Device CapThe S3
    1. This is a non-critical error if you are running the system on a first generation Hyper-v virtual machine. Video driver isn’t supported in Windows 2012r2.
  2. Active Directory on this domain controller does not contain Windows 2012 ADPREP /FORESTPREP updates.
    • The domain needs to be prepped. The link Microsoft provides might give you some insight but does not contain the correct info.
    • The link they provide is: http://go.microsoft.com/fwlink/?linkid=113955 – This link isn’t correct. See info further down in the post.

Here’s what the report looks like. It’s located on your desktop after a failed upgrade.

report-dc-upgrade

As you can see the link only talks about upgrading from really old OS’s to 2008/2008R2 domain controllers and not 2012r2.

At step 4 it says to run adprep from the OS disk to prepare the machine.

  • D:\sources\adprep\adprep /forestprep

ADPrep is no longer found in this directory! It now can be found in:

  • D:\Support\Adprep

forestprep-01

It will run and you will be presented with some info. The main parts are:

  • All Dc’s Must be Windows 2003 or later
  • Can’t be reversed
  • Hit “C” to continue
  • Hit “ENTER” to EXIT

The command output is a few screens in length. Here is the output of the command in my test DC.

forestprep-03

forestprep-04

Now guess what! You also have to upgrade:

  • Domain:
    • adprep /domainprep
  • Group Policy
    • adprep /domainprep /gpprep
  • RoDC
    • adprep /rodcprep

These commands are similar to the first ADPREP command you entered.

Here is the output from those commands:

forestprep-05

The group policy should already be updated but I like to still run the command to make sure:

forestprep-06

Again you shouldn’t need to run this command but I do it anyways to make sure:

forestprep-07

Rerun the install and you will see you can now hit “NEXT” after the compatibility report!

windows28-dc-upgrade

Voila! Your Upgrade is underway!

FIX – Application pool cannot be deleted because it contains 1 applications.

Are you getting the error message: There was an error while performing this operation. Details: Application pool “<name>” cannot be deleted because it contains 1 applications?

The only way I could figure out how to delete it was using Powershell.

How-to-delete-web-pools_000

How-to-delete-web-pools_001a

How-to-delete-web-pools_002

Here are the Powershell commands:

  1. import-module WebAdministration
  2. iis:
  3. ls *optional* This just shows you the AppPools folder exists
  4. cd AppPools
  5. dir
  6. del *name_of_Web_Pool*
  7. Will ask you if you really do want to remove the App Pool. “Hit A for “Yes to all”.
  8. ls – This will allow you to verify the AppPool is gone.

You can now go back into IIS and verify that the AppPool is no longer there!

How to find the SID of a User (Local/Service/Domain/Microsoft)

There are 4 main SIDs that I know of:

  1. Local User
  2. Service
  3. Domain (AD user)
  4. Microsoft User (Part of Windows 8/10) – Users authenticate against Microsoft servers.

To Find them on the local machine you need to go to Regedit and find:

  • HKLCM
    • SOFTWARE
      • Microsoft
        • Windows NT
          • Current Version
            • Profile List

In “Profile List”, you will find the SIDs of the computer.

SIDs can have two “looks”. Many people call them:

  • Short SIDs
  • Long SIDs

The short SIDs tend to be for local users and services whereas the long ones are used for Domains and Windows Users.

sid-001b

If you look at the “ProfileImagePath” you can figure out what user or service the SID resolves to. In the screenshot above:

  • S-1-5-18 -> “SystemProfile”
  • S-1-5-19 -> “Local Service”
  • S-1-5-20 -> “Network Service”
  • S-1-5-21 – [Long SID] -> My account.
