Recover lost Bitlocker Recovery Key (also for non-AD computers)
edited by on May 13th 2015, at 14:34

If you accidentally have misplaced or forgotten your Bitlocker Recovery key, but still have access to the system (with an elevated account), you can retrieve the recovery key quite easily through the command line:

Open an elevated command prompt and type:

manage-bde -protectors -get C:

Replace C: with any drive that has Bitlocker enabled. Note that if it's not the system volume but some other drive that's encrypted, you need to unlock it first before you can retrieve the recovery key.

Call redirection on your cellphone (for Proximus)

The dial codes for setting up call redirection on your cell. These codes are specifically for Proximus (Belgian carrier), but may work with your carrier as well.

RedirectionActivateDeactivateReactivate
immediate**21*number###21#**21#
after 15 secs**61*number###61#**61#
when busy**67*number###67#**67#

It's recommended to specify the number in international notation (+country), even for national calls.

Reactivation means it's activated with the number you specified last time.

 
Trend Micro Officescan: silent install via AutoPCC utility
edited by on May 8th 2015, at 14:29
The Trend Micro OfficeScan client can be installed on a workstation via the network (using an UNC-path) through the AutoPCC utility. The client can simply browse the OfficeScan server, locate the autopcc.exe utility, and run it, performing an installation of the OfficeScan client on the computer running the utility. By default, the installation of the client is not silent, meaning the user will see windows and dialogs appearing. Fortunately, it is possible to make AutoPCC to perform the installation completely silently, leaving the user almost unaware that an installation of OfficeScan is occurring.

To change this setting, log on to the OfficeScan server, and browse to the OfficeScan instal  ...
 
Samsung Galaxy S5 cannot connect/find 5ghz Wifi network
edited by on May 8th 2015, at 13:16

If your Samsung Galaxy S5 may not find or be able to connect to a specific 5Ghz wireless network, you may want to check which channel the network is operating on. The S5 has problems when trying to connect to DFS-channels (Dynamic Frequency Selection).

DFS-channels are basically every channel from channel 52 and up. Try setting your AP to a channel between 36-48 (inc.), and then try reconnecting your S5.

 
VMWare vSphere client on high DPI settings
edited by on May 6th 2015, at 09:20

You may have noticed that running the VMWare vSphere client on a display with higher DPI settings causes problems with the mouse cursor alignment when working inside a VM. This is because of a mismatch between the DPI settings of the VM and the DPI settings of your computer.

To resolve, right-click the shortcut to the client, go to the Compatibility tab, and enable Disable display scaling on high DPI settings.

The downside of this method is that there will be misalignment of some parts in the client, but it is still workable and moreover, it solves the mouse issue in a VM.

 
Change location of Kodi's data directory (workaround)
edited by on May 5th 2015, at 13:05
By default, Kodi (formerly known as XBMC), stores its data directory in the user's home folder (Mac/Linux) or roaming profile (Windows). Sometimes, this may not be desirable, especially when you have only a limited amount of space available on that particular drive (such as having a Windows installation on an small SSD). In that case, you may want to move the entire data directory (including the profiles, thumbnail caches and database files) to another drive.

There are various ways to achieve this, but I found out the most easiest (and also complete way) is to simply move the entire folder to another partition or disk, then symlink that folder to its original location. That way, you won't h  ...
 
Internet Explorer tries to "save" any and all websites and HTM/HTML files
edited by on May 5th 2015, at 12:47
In rare cases, Internet Explorer (any version) tries to always "save" any and all website pages, and locally opened HTM/HTML files. Additionally, you cannot open the About Internet Explorer dialog box (it is either grayed out or nothing happens). There isn't a single cause for this so I tried listing some things you can try to resolve the matter.

Avast is known to cause this because of its SandBox module. Try disabling it, or (temporarily) uninstall Avast entirely.

Security bulletin MS14-021 provides an update, KB2964358, which can cause this if not all previous security updates for IE have been installed. Uninstall the patch, then install all security updates (accept this one),   ...
 
Windows Update error 0x80072EFD
edited by on May 5th 2015, at 09:37

If Windows Update (or Microsoft Update) produces error code 0x80072EFD, you are most likely blocked by a firewall or a proxy.

  • Check any firewall that may be blocking access to the update sites. This includes any software-based firewall on the server, as well as network firewalls and content filters.
  • If you have configured a proxy, check whether the proxy is reachable and does not block access. If you don't have a proxy server (anymore), it may still be configured. See this article on how to check and resolve.
 
Adding ESX host to vCenter: Cannot install the vCenter agent service
edited by on April 29th 2015, at 16:49
When attempting to add an ESX host to vCenter, you may get one of the following errors:

Error #1
Cannot install the vCenter agent service: Cannot upload agent.

Or:

Error #2
Cannot install the vCenter agent service: unknown installer error

Below is a list of most common errors:

Check whether the host is accessible through port 902/tcp. Check the firewall settings and/or routing between the ESX hosts and the vCenter server.

Check whether there is sufficient space on the ESX disk. If there's not enough space, this often gets logged in /var/log/syslog.log during the installation of a VIB.
Usually the problem occurs with the tmp partition (i.e. scratch disk) being full or almost full. You n  ...

Completely restarting VMWare ESX (management) agents
edited by on April 29th 2015, at 14:00
Sometimes it may be required to do a full restart of agents and services on a VMWare ESX host. You could do a full reboot, but this requires all VMs to be shut down or moved to another host. Fortunately, it is also possible to do a complete restart of services on a host without affecting the VMs running on it.

There are two ways of doing this, depending on whether you have direct access to the host, through console or through a remote management system like HP's iLO or Dell's iDRAC, or have to do it remotely.

Note that using the Restart management agents function from the console is not the same as a full restart of all services.

Use this method if you have access to the host directly thr  ...
 
Enable SSH server on a VMWare ESX host
edited by on April 29th 2015, at 13:18
There are two ways to enable the SSH server on a VMWare ESX host, through the vSphere client or through direct access through the console.

Use this method if you have access to the host directly through console, or when you can use a remote management system such as HP's Integrated Lights-Out or Dell's iDRAC.

If you can't log on using the vSphere client, this is the only way to enable the SSH server.

Log on to the console using the root account.

In the menu, go to Troubleshooting, then enable the SSH server.

Log on to the ESX host through the vSphere client. You can also log on your vCenter server to enable the service.

Click on the host (in vCenter or when logged in directly on the ES  ...

Configuring port forwarding on Dell Sonicwall
edited by on April 28th 2015, at 15:24
This article is a quick reminder (for myself) on how to properly configure port forwarding on a Dell Sonicwall firewall.

First, create the address and services objects you need for the port forwarding. In case of multiple addresses or services, create a group and add all objects in that group.

Address object for a local server



Service group with multiple services



Predefined objects, such as the WAN IP are already present and do not have to be created again. Also, the advantage of using these predefined objects is that they are dynamic: e.g. if the WAN IP changes, the policies and rules that use this object will not have to be changed.

Once the objects are in place, they can be refer  ...
 
Adding shared contacts folders to the Outlook Address Book
edited by on April 28th 2015, at 13:53
When attempting to add another user's (shared) contacts to your own Outlook, you'll notice that you won't be able to access these contacts from the Outlook address book. Additionally, when right-clicking the shared contacts folder, you'll notice you can't choose to display the contacts in the Outlook address book.



The reason for this is that Outlook simply does not allow it. Quoted from an Exchange engineer:

Engineer from exchange server
By the current outlook design, it’s not possible to implement the shared contacts folder in the Outlook Address Book. The Outlook Address Book tab feature is ‘by design’ unavailable for shared contacts folders and this is hard-coded in the Outlook   ...
 
Certain smartcard readers not detected after upgrade to OS X Mavericks
edited by on April 27th 2015, at 10:59
Smartcard readers that use the OpenSC PCSC daemon in order to work may no longer work after upgrading your Mac OSX to Mavericks (10.9). This is because of a problem that occurs with the PCSCD after the upgrade. Affected card readers are all that use this daemon for its communication. Examples are most ACR38U-based card readers, certain Vasco DIGIPASS readers, and some others.

The solution is to re-install the PCSCD package, which will fix corruption and make sure the daemon is started properly, enabling the card reader again.

Download the PCSCD-autostart package from the Vasco website.

Install this package. Note that you may have to circumvent the built-in application security, as  ...
 
VMWare SRM install error: Failed to Clear Inventory Service Registration
edited by on April 23rd 2015, at 11:05
When upgrading or reinstalling VMWare Site Recovery Manager (SRM), you may run into the following error:

Error message
Failed to Clear Inventory Service Registration

This error can occur when you attempt to upgrade/reinstall SRM, and have decided to clear out the SRM database, or when you have done a reinstall of vCenter, the inventory service, or have cleared out the Inventory Service database.

There are two ways around this.

Keep the old SRM database instead of overwriting it, but after the installation, you will manually have to clean up the existing database, since you wanted to clear out the old data in the first place.

Alternatively, and more easily done, is to remove the database  ...
 
Difference between AutoComplete and Suggested Contacts in Outlook
edited by on April 22nd 2015, at 14:01

From KB 2682333:

Outlook also adds a folder to Contacts labeled Suggested Contacts. Addresses get added to this folder as you send or reply to messages addressed to people who don’t exist in your Contacts folder. Outlook doesn't look in Suggested Contacts for names during the AutoComplete process. It only stores addresses that you might want to add to your Contacts. You can double-click an entry in Suggested Contacts and a Contact Form opens that allows you to save it to your Contacts Folder.
