Microsoft still does not enable NTP time sync by default on their servers. You can very easily manually enable it using the Windows Time Service, which supports time synchronisation from an NTP time server.

Open up an elevated command prompt on your server to begin.

To specify one or more NTP time servers:

w32tm /config /syncfromflags:MANUAL /manualpeerlist:0.europe.pool.ntp.org

Time sync does not automatically start, so you have to restart Windows Time Service:

net stop w32timenet start w32time

To query the status of the time sync:

w32tm /query /peers

You should get some output like this:

#Peers: 1Peer: 0.europe.pool.ntp.orgState: ActiveTime Remaining: 57.2511002sMode: 1 (Symmetric  ...

The Cisco VPN client v5.0 does not work out-of-the-box on Windows 7 and 8. Starting the VPN will result in an error:

Error
Reason 442: Failed to enable Virtual Adapter

This is because of a malfunctioning installer, creating an invalid connection to the Cisco VPN Adapter. To resolve, follow the steps below.

Open regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA.

Look for the DisplayName value and change it to remove all leading characters up to and including %;:For x86, the value change from something like @oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter to Cisco Systems VPN Adapter

For x64, the value would change from something like @oem8.inf,%CVirtA_D  ...

Currently, vCenter Server 5.1 is not supported on Windows Server 2012. Trying to install usually results in several errors, but they can be resolved with some workarounds and things to consider. This post is a gathering of (some of) those things.

First of, be sure to install .NET 3.5 using the Server Manager. It can be found as a feature. The installation delivered in the vCenter installation cannot be installed.

It's best to install the required components (SSO and Inventory Service) separately to ensure the installation of the different components goes smoothly. You will have to type in and remember the SSO passwords though.

Upon installation of the vCenter Server, it will insta  ...

The Windows Recovery console allows you to boot into a CLI which you can use to resolve issues when Windows no longer boots. Normally, you would start the console from the installation CD/DVD, but you can also install it so the installation media is no longer required. Instead, you get an additional option in the boot menu where you can select it.

To install it, insert the installation media, open up a command prompt and run these:

x:cd \i386winnt32.exe /cmdcons

This will install the recovery console. If you get an error about a too new version, you may have to slipstream the latest service pack into your installation media. You can also run the installer from a local path (i.e. copy t  ...

By default, Azure blocks all access to your SQL Azure database, unless you specifically add firewall rules for your IP. In some cases you may need access from any IP in the world (e.g. when you want to use Remote Desktop Manager through Azure and require access from any IP). In this case, you have to adjust the firewall so access from all IP's are allowed. Here's how.

Warning
Allowing public access to your SQL database effectively opens up access from anywhere, increasing the risk of unauthorized access. Do not use this with in a production environment, or with sensitive data. Change the login and password to your database to something very complex.
In case of Remote Desktop Manager, enable  ...

You can change the delimiter of a for-loop by changing the value of the global variable $IFS. By default this is set to a space.

For example, if you want the delimiter to be a new line, set it like so:

Occassionally, Windows 7 has a tendency to automatically create an excessive amount of various tunnel adapters, ranging from isatap, 6to4 and Teredo. The result is a slowdown during startup because of all the interfaces, and ifconfig's output gets cluttered.

You can manually remove the interfaces through Device Manager. Start it up (run devmgmt.msc), then turn on hidden devices:



Under Network adapters, you'll find the whole list of adapters, starting with Microsoft 6to4 Adapter or Microsoft ISATAP Adapter, followed by a number. You can manually delete ("uninstall") all but the unnumbered adapters.

There are also ways to automatically uninstall these adapters, which is recommen  ...

When attempting to send and receive e-mail in Outlook 2010, you may get the error:

Error
Outlook data file cannot be accessed (0x8004010F)

This occurs when the Outlook profile is somehow corrupted.

You can attempt to resolve the issue by re-setting the delivery location in your Accounts, but sometimes this does not work, and the delivery location remains unset. In this case, you have to create a new Outlook profile, recreate your e-mail accounts in it, set the delivery location and reopen any other Outlook data files.

Since a recent update of OSX, there's an issue with the Java-plugin not being active, even though Java Control Panel says it is. This is because in Safari the plugin is still set to inactive.

To resolve, surf with Safari to www.java.com/nl/download/testjava.jsp. You see the Java website with in the center the notification that the plugin is not active. Click on the text to re-active the plugin.

If you've lost the password to the Trend Micro OfficeScan web console, you can attempt to reset it to something known by editing a certain file using notepad.

Find the file C:\Program Files\Trend Micro\Officescan\PCCSRV\Private\ofcserver.ini. Open it with notepad and look for the parameter master_pwd. Change its value so the parameter reads:

master_pwd="!CRYPT!523F7DC2E525044E2800FCDEA7E5D78B70C0A4165387060525E3EE66D5D2D2F460EA361E712B5F871FD473C7A6C"

Using this hash changes the root password to trendmicro. Restart the OfficeScan Master service (via Services) to apply the new password.

With newer versions (10.0), you may also have to edit the file C:\Program Files\Trend Micro\O  ...

If you don't know the password of your Trend Micro OfficeScan client, you can still do the uninstallation by changing a value in the registry.

  1. As an elevated user, start up regedit.
  2. Navigate to the key HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\Misc.
  3. Find the value Allow Uninstall and set it to 1.

You should be able to uninstall the client without a password prompt.

Almost forgot about these, and as I've never posted their links before, there they are:

  • XPize is a GUI enhancer for XP
  • Vize is a GUI enhancer for Vista

Both run on the same engine. These tools can almost completely change the appearance and visual styles of XP and Vista.

Starting from Windows 7, there's a folder %systemroot%\WinSxS which is part of the Windows Side-by-Side system. Incidentally, this folder can become quite large, usually because installing updates or new applications often installs new versions of components in the WinSxS folder while keeping the old versions. There is a way to clean up these old versions by running the command:

dism /online /cleanup-image /spsuperseded

Additionally you can also use the disk cleanup tool to remove old service pack backup files.

If a host cannot be managed via vCenter or from vSphere client, you can still use the CLI (on the host itself or via network using SSH or vSphere CLI/RCLI) to partially manage the VMs on the host.

For this to work you must have already enabled the local console, Tech Support Mode and/or SSH access:

Enabling root SSH login on an ESX host (8375637)

Tech Support Mode for Emergency Support (1003677) (ESXi 3.5 and 4.0 only)

Using Tech Support Mode in ESXi 4.1 and ESXi 5.0 (1017910)

Once logged in, you can use these commands to control the VMs. Note that there are differences between ESX and ESXi.

The Computer Maintenance service in Windows 7 sometimes has a tendency to automatically remove desktop shortcuts to network locations, which can be really annoying. You can turn off this service locally or via GPO to prevent the shortcuts from being removed automatically.

Through Control Panel → Troubleshooting. On the left, select Change Settings, then choose to disable Computer Maintenance.

The policy setting is located at Computer Configuration\Administrative Templates\system\Troubleshooting and Diagnostics\Scheduled maintenance. Set the policy setting Configure Scheduled Maintenance Behavior to disabled.

Note that you need the Windows 7 (ADMX) Templates (download: http://w  ...

Windows Fax has some shortcomings concerning how address lists are being used. The original design was to allow the Windows Fax client to use Outlook's address lists whenever Outlook was installed. However, due to incompatibilities between 32-bit and 64-bit, there are some issues where the fax client would not use Outlook, even though Outlook has been installed properly. Unfortunately, if such is the case, there's no real solution, other than switching the architecture of the OS or upgrading to a newer OS. I've jotted down a short and simple matrix of OS and Office versions to indicate which combination is known to work properly with Outlook's address lists.

If Windows Server backup occassionally gives you a timeout, and you get the following error:

Error
The shared protection point operation failed with error 0x81000101.

This error is caused when the volume shadow copy is taking more than 10 minutes and is timing out. You can try to increase the timeout value to fix this issue. This is done by adding a registry key:

Fire up regedit.

Navigate to key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\SPP.

Create a new DWORD value with name CreateTimeout, set its value to the number of millis.
For 20 minutes this would be decimal 12000000 (20·60·1000).

Try re-running the backup. The timeout should no longer occur.   ...
