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.

Although there are several Windows 10 devices that are touchscreen-based, the mouse still remains to be an important part of usage for many users especially the ones who do some hardcore work on their Windows 10 computers or laptops. If you’re one of the users who often edit images or videos either for fun or work, using Touch is difficult as it’s a bit hard to drag on the screen so nothing really beats the mouse. However, as awesome as the mouse is, there are times when you encounter issues while using it. One of these issues is when your mouse pointer lags or freezes so in this post, you can try out a few tips that can help you resolve the issue.

Option 1 – Clean both the mouse and the mousepad

It might sound silly but it is a fact that either the mouse or the mouse pad themselves is the problem. Even though mouse balls are long gone, the laser lights that replaced them are not immune to some dirt which is why you need to clean the bottom of the mouse and then clean the mouse pad afterward.

Option 2 – Try changing the USB port

This is another basic thing you can do to resolve the problem since there are instances when USB ports where either your mouse is connected have gone rogue so you need to try switching to a different port and then see if the problem’s fixed or not.

Option 3 – Switch back to the default settings of the mouse

Switching your mouse back to its default setting is always a good idea since you are dealing with a pointer issue. To go back to the default settings of the mouse, here’s what you have to do:

• Click on Mouse and Touchpad.
• Next, click on Additional Mouse Settings located in the right pane.
• After that, click on the “Use Default” option under the Pointer tab.
• Then click on Apply and OK to save the changes made.

Option 4 – Try disabling Smooth Scrolling

You have to slow down both the horizontal and the vertical scrolling of the mouse in the settings which are called “Smooth scrolling”. This will help if you think that the websites you are visiting scroll up and down way too fast.

Option 5 – Try to update or rollback mouse drivers

If the first few options didn’t work for you, then it’s time to either update or roll back the mouse drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated the mouse driver then you need to roll back the driver. Whichever applies to you, refer to the steps below. The problem may be caused by a corrupted or outdated driver. So you have to update or reinstall the mouse driver. How? Follow these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the Mouse and other pointing devices and right-click on the mouse driver to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, disconnect the mouse and plug it back in to reinstall the mouse driver.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 6 – Try to check if your laptop is turning off the mouse

In case you don’t know, the power management can turn off the devices that are not in use to save battery power if you use a laptop. And this can also happen on USB-based devices like the mouse. Thus, you need to verify if your laptop is turning off the mouse.

• Go to Device Manager > Universal serial bus controllers > USB Root Hub > Power Management.
• After opening Power Management, uncheck the “Allow the computer to turn off this device to save power” option.
• If you have lots of USB Root hubs, you can try changing each one of them and see if it works or not.

Option 7 – Try updating the Graphics Drivers

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it.

Option 8 – Try setting the No Delay option for Touchpad

If you are using a laptop that’s touchscreen-based, you can try setting the delay to zero in the settings. To do so, simply go to Settings > Devices > Mouse and Touchpad. From there, you can set the delay before clicks to “No Delay”.

The New and upcoming HAF 700 Evo from Coller master is a beast of a case, but so is its price. The case itself is still not released but as sources say it will be soon, well at least we hope so. The price will be around $500 which is a little on the expensive side of things but the features it is bringing are very impressive.

HAF 700 EVO Size and its advantages

HAF stands for High Airflow and with this case, you are going to get it but first let us talk about other characteristics of the case. Firstly case is ATX full tower, pretty big going 24.64 x 11.45. x 26.22 inches in size but like all full tower cases it can hold all motherboard types including Mini-ITX, Micro-ATX, ATX, E-ATX. The large case size also lets you place a pretty big GPU, going to 19.29 inches (490 mm) in its length covering currently all available Graphic cards on market.

Being a very big computer case is not just placing motherboard and big GPU, there are other great advantages of it, firstly that you can go wild with your CPU cooler, going all the way to 6.5 inches in cooler height will satisfy all users and having 12x 2.5 or 3.5-inch internal bays will. And if even that is not enough you have 8 expansion slots available.

Inside HAF 700 EVO

Inside the casing you will also find 2 front fans with 200mm diameter, 2 rear fans sized 120mm, and 1 bottom fan of 120mm. You can also manually mount standard 120mm fans on top of the case for maximum airflow.

Front panel and outsides

The front side is filled with 4x USB 3.2 Gen 1 Type-A (5 Gbps), 1X USB Type-C (up to 10Gbps), 3.5mm both headphone and audio jack along with a reset switch. Also, the circle in the very front is a hi-resolution LCD customizable display, you know, just to add more flavor and personal touch to the case. Fron is also filled with glass panels emitting RGB light.

Of course, you must also have a Tempered Glass Side Panel and well weight of 53.57 pounds (24.3 kg), yup you read that correctly, beside its hefty price tag this cooler master beast also is pretty heavy. Granted all of the weight comes from the glass front panel it is still a little hard on moving and taking out of the box.

This is also the case where you will not need a single screwdriver, everything is made to be assembled with your hands alone pushing easy assembly into the front row.

Conclusion

So in the end what are my thoughts about this expensive and heavy PC case? Would I recommend it? The answer to that question could depend really on your budget, let us be really honest here if you can afford it, YES, wholeheartedly I would recommend the case, it is great, it feels great, it looks great and the airflow is amazing. However, if you are tight on a budget, there are other great cases with excellent airflow and you might want to skip this one.
