What is Error 0xe0434f4d?

Error 0xe0434f4d displays when a remote computer runs an instance of the SQL Server 2005 but it fails to initialize. When the plan is started, this error displays in a status window on the SQL Server. Also, when the Update-OffilineAddressBook cmdlet is started in Microsoft Exchange Server, this error can occur.

Solution

Error Causes

Error 0xe0434f4d can occur for possibly two main reasons. The first one is when the System Attendant Service is not properly running, and the second when you don’t have the permission to run the update. Other causes are when the .NET Framework 2.0 security does not allow sqlplanlaunch access to run from a shared network. Another cause is when the Offline Address Book (OAB) is not found in the Configuration Domain Controller server that the server of OAB generation uses.

Further Information and Manual Repair

In case you didn’t know, the Offline Address Book generation server is a mailbox server, and in order to resolve error 0xe0434f4d, you will have to replicate the OAB object to the Configuration Domain Controller server. In order to do so, follow steps:

• Go to start and click on All Programs, then go and click on Microsoft Exchange Server 2010. Click on Exchange Management Console
• In Exchange Management Console, go to Server Configuration and click on Mailbox
• In the details, go to mailbox server that generates Offline Address Book and right-click it, then go to Properties
• In the Properties, click on System Setting and locate the domain controller name in the box that reads Domain controller servers being used by Exchange

Make sure the OAB object is reproduced in the Configuration Domain Controller Server. Follow these steps to do that:

• Go to Start and click on Run. Type Adsiedit.msc in Open box and press Enter. Right-click on ADSI Edit and click on Connect to
• Locate a list reading Select a well-known naming context, and from there select Default naming context. In a Select or type a domain or server window, type FQDN (fully qualified domain name) of the Configuration Domain Controller server which was determined in step 1, and click OK
• Expand Configuration [dc.domain.com], expand CN=Configuration, DC=domain, DC=com, expand CN=Services, expand CN=First Organization, and expand CN=Address Lists Container
• Click on CN=Offline Address Lists and make sure the OAB object is listed on the details pane

When the OAB generation server receives this, then it will connect to the Configuration Domain Controller server and will locate the OAB object. If the OAB generation server is unable to find the OAB object, then the error will return on the cmdlet. On SQL Server, you should change the .NET permissions to allow sqlplanlaunch application access to run from shared administration. For that, follow these steps:

• On ArchiveIQ Server, open System from the Control Panel and note down the computer name
• On SQL Server, log in as administrator and open the command prompt
• On the command prompt type, ‘C:windowsmicrosoft.netframeworkv2.0.50727caspol.ece –m –ag l – url file:\[Archive IQServer Computer Name]AlQRemote$*FullTrust and Press Enter. Type yes and press Enter again to confirm the permission changes.

As you know, Windows 10 comes with a pre-packed feature that allows you to rotate the screen at different angles, and to facilitate this feature, there are keyboard shortcuts you can use as well. However, from time to time, no matter how useful this feature is, users still experience a handful of issues. One of which is that they suddenly find their screen rotated or Upside Down even when they didn’t do a thing or adjust the setting. You may have pressed the shortcut on the keyboard by accident or some other program changed the setting on your computer without your permission – whichever the case is, this post will show you what you can do to fix the upside-down screen on your Windows 10 PC using the options laid out below.

Option 1 – Try using hotkeys

Option 4 – Check your monitor’s physical controls

There are monitors that have buttons in them that allows users to shift the rotation of the screen to 90 degrees. It could be that your monitor has these buttons without you knowing and you suddenly pressed them by mistake which caused your screen to rotate. Thus, you have to check your monitor for any physical buttons on the side and if you see a menu, navigate to its options and check if there are screen rotation options. To make it easier for you, you can simply search your monitor’s model online and see if these buttons exist. You could also go over your monitor’s manual if you still have it as it contains details with regards to screen rotation.

Option 5 – Update your Graphics drivers

• Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.
• From the drop-down menu, select the Update Driver option if you wish to update the driver or select the Uninstall device if you want to uninstall the driver and then follow the on-screen instructions to install the latest version of the driver.
• Restart your PC after the installation to allow the system to reinstall the driver.

As you know, one of the most highlighted features of Windows 10 is Windows Updates. It was offered to the customers as a service rather than a product with the release of Windows 10 under the scenario of Software as a Service which led to Windows Updates being set by default on Windows 10 and without an option for any users to disable it. Although not all users are happy with what Microsoft did, this is an ultimate step towards the greater good of all its customers since Windows Updates helps users in keeping their computers secured against all kinds of threats as well as provide them with the greatest and latest updates from Microsoft. So if you are one of those users who approved of the Windows Updates service, then read on as this post will guide you in running Windows Updates from Command Line either via Command Prompt or Windows PowerShell. For the complete set of instructions, refer to the options given below.

Option 1 – Run Windows Update via Command Prompt

Command Prompt in the Windows operating system exists for a very long time now compared to the comparatively new Windows PowerShell. That’s why it has similar capabilities to run Windows Updates. However, the highlighting point here is that you don’t have to download any module for Windows Updates. To get started running Windows Updates using Command Prompt, refer to the steps below.

• First, type “cmd” in the Cortana search box, and from the search results, right-click on Command Prompt and select the Run as Administrator option to open it with Administrator privileges.
• If a User Account or UAC prompt appears, just click on Yes to proceed.
• Next, type in the commands listed below, and don’t forget to tap Enter right after you type each one of them.
  • UsoClient StartScan – use this command to start checking for updates.
  • UsoClient StartDownload – use this command to start downloading updates.
  • UsoClient StartInstall – use this command to start installing the downloaded updates.
  • UsoClient RestartDevice – use this command to restart your computer after you install.
  • UsoClient ScanInstallWait – use this command to check, download and install updates.

Note: Keep in mind that the commands in Command Prompt listed above are only meant for Windows 10. On the other hand, if you are using an older Windows version, you can try using the following commands instead:

• wuauclt /detectnow – use this command to start checking for updates.
• wuauclt /updatenow – use this command to start installing the updates detected.
• wuauclt /detectnow /updatenow – use this command to check, download and install updates.

Option 2 – Run Windows Updates via Windows PowerShell

If you run Windows Updates in the Windows PowerShell, it will require you to install the Windows Update module manually. Hence, you have to get the Windows Updates downloaded and install Windows Updates.

• Search for PowerShell in the Cortana search box and then run it with administrator privileges.
• Once you’ve opened the Windows PowerShell, type the following command and hit Enter.
  • Install-Module PSWindowsUpdate – use this command to install the Windows Update module for Windows PowerShell.
  • Get-WindowsUpdate – use this command to connect to the servers of Windows Update and download the updates if found.
  • Install-WindowsUpdate – use this command to install the Windows Updates you’ve downloaded to your computer.

In case you don’t know, Microsoft hooks up every machine that is running Windows 10 with an Advertising ID which helps them in providing Windows 10 users with relevant ads. These ads are delivered to users in the Action Center, Start Menu as well as the ads inside the UWP Applications. What makes these advertisements relevant is that they keep track of your browsing trends, likes and dislikes, with the help of the Advertising ID. However, if you are not fond of advertisements and you do not want this feature of Microsoft to track your usage, worry not for you actually have the option to disable targeted ads on your Windows 10 computer by turning off the Advertising ID. And you can do that during Windows 10 Setup or using the Group Policy Editor. For more details, refer to the instructions provided below for each one of the methods.

Option 1 – Turn off Advertising ID during Windows 10 setup

If you are about to install Windows 10, then during the installation process, your computer boots into the Install and Configure Windows 10 screen with Cortana that assist you during the setup. Once you reach the last page which is “Choose privacy settings for your device”, you will see the Advertising ID of your computer. Under the Advertising ID, you have to disable or toggle off the “Apps can use advertising ID to provide more personalized advertising in accordance with the privacy policy of the app provider” option. After you disable it, click on the Accept button to proceed with the installation. After that, the copy of your Windows 10 you are using will have the Advertising ID disabled by default.

Option 2 – Turn off Advertising ID via Group Policy Editor

• First, tap the Win + R keys to launch the Run utility.
• Then, type “gpedit.msc” in the field and click OK or tap Enter to open the Group Policy Editor.
• Next, navigate to this group policy setting: Computer Configuration > Administrative Templates > System > User Profiles

“This policy setting turns off the advertising ID, preventing apps from using the ID for experiences across apps. If you enable this policy setting, the advertising ID is turned off. Apps can’t use the ID for experiences across apps. If you disable or do not configure this policy setting, users can control whether apps can use the advertising ID for experiences across apps.” Note that setting the radio button to Enabled or Not Configured will turn off the data collection of the Advertising ID.

• Finally, exit the Group Policy Editor and then restart your computer to apply the changes made successfully.

The “Unknown Hard” error that keeps on appearing in Windows 10 can put users in an unpleasant situation. This kind of error leads to the freezing of the taskbar, blackening of the screen, and sudden disappearance of the icons on the Desktop. And each time you try to open Windows, the system will only give you an error message saying that it’s a critical error and some applications like Start and Cortana won’t work. Upon analysis, it seems that the “sihost.exe” is not responding and that it is the one that’s causing the c000021a Unknown Hard error to pop up. Sihost.exe files represent the Shell Infrastructure Host which is an essential component in the Windows operating system. The Windows Shell Infrastructure Host is primarily responsible for handling some graphical elements of the operating system interface such as the Start menu and the taskbar transparency. And so if the Shell Infrastructure or Sihost.exe has stopped, has been removed, or corrupted, you will most likely have issues with the overall functionality of the Windows operating system and you’ll get the Unknown Hard error In addition, the ctfmom.exe Unknown Hard error may also occur due to incompatible drivers installed on your PC. Ctfmom is a process that identifies inputs such as handwriting, languages, and many more. It’s the one that controls the functions of background behavior. To resolve this issue, you need to first try to identify which application is the one that’s running the sihost.exe file. And if needed, you need to either update or reinstall or completely uninstall the problematic application.

Option 1 – Try to run the System File Checker

The SFC Scan or System File Checker, us a built-in utility in Microsoft Windows that can be found in the C:\Windows\System32 folder. This tool allows users to scan and restore any corrupted system files in Windows that might be causing the Unknown Hard error to appear. Before you use this tool, make sure to find out whether the sihost.exe on your computer is a Trojan that you have to remove or if it’s a file that belongs to a trusted Windows application. Once you have that sorted out, follow the steps below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 2 – Try to use System Restore

You can also try using System Restore. This is one of the ways you can use it to back up your PC. Since restore points are created automatically each week by System Restore, you can use System Restore to restore your computer back to an earlier good point in time.

Option 3 – Try to troubleshoot the error in a Clean Boot State

Putting your PC in a Clean Boot state can help you diagnose and troubleshoot the issues in your system. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the Unknown Hard Error.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.
