In case you have issues on your Windows 2003 concerning VSS, Microsoft has an update rollup available for download to fix certain issues with VSS:

Ever since the official announcement of the iPhone 4S, I'm reading basically everywhere on how disappointed the fans were about the iPhone 5 not being announced, but instead the iPhone 4S was...

To all those sites and fans (which in my opinion aren't really fans): why are you nagging about the iPhone 5? There never ever was an official announcement or rumour about the iPhone 5 ever being announced or released. The iPhone 4S is the next generation of the iPhone. So what's it's not called the iPhone 5? It's only a name, invented by those spreading rumours in the first place. It never was announced by Apple at all. So cut the cr*p and move on...

When adding additional backup disks to your Windows SBS 2011 server backup, you may get an error stating:

The filename, directory name, or volume label is incorrect.

The problem occurs with the SBS console and when running the Server Backup snap-in.

You can work around this issue by manually adding the backup disks via the wbadmin command line tool.

Connect the disk you wish to add to the system. Open up a command prompt.

Fetch a list of available backup targets by running:wbadmin get disks

You need the DiskID displayed of your backup disk.

Add the disk to the backup pool by running:WBADMIN ENABLE BACKUP -addtarget:"{DiskID}"

Replace the DiskID with the one you have,   ...

The following was tested on a Windows 2003 R2 with SP2, but it should work on every system with w32time installed.

Open up a command prompt (start, run, cmd.exe, you know).

Then punch in these lines:

net time \\your-server-name /setsntp:some-ip-or-pool.ntp.orgnet stop w32timenet start w32time

The way NTP works, the sync does not occur immediately, but it should be visible within a few minutes after w32time has started again.

If it doesn't work for you, check whether your time zone is correct, and whether the time of your server and the real time differs with over 3600 seconds. Ntpd would not sync if the difference was over an hour.

To query the current NTP servers  ...

Since Windows 7, the Quick Launch bar has been removed from the taskbar, and the pinning of applications has been introduced as a replacement. Not everyone likes this new feature, or perhaps you want to have the old Quick Launch bar back anyway. Well, it can be restored, albeit with a bit of a workaround.

The Quick Launch bar in earlier versions of Windows in fact nothing more than a folder containing shortcuts. With this in mind, it's in fact quite easy to add the Quick Launch bar, in this case as a regular folder.

First, unlock the taskbar. You need this to move over the Quick Launch bar once it's added, and to access its settings to actually make the toolbar look like the old Quick Laun  ...

When running virtual Windows 2003 systems (e.g. in VMware), it's sometimes necessary to increase the size of the disks to add more storage to your machine. Starting from Windows 2008, you can perform an online increase of NTFS partitions using Storage Manager. In Windows 2003, it's also possible to perform an online extend by using diskpart from the command line.

First, make sure to extend the physical volume (e.g. by increasing the virtual disk size in VMware). Then open a command prompt and run diskpart without parameters.

To extend, you have to select the physical disk and volume. To know what to select, you can view the available disks and volumes.

List and select the physical disk:

If you wish to restrict SMTP access via IP addresses or a network range, one way to do it would be via Postfix configuration. You can set up restrictions using a Postfix hash-table or via a cidr file. You can choose one or both methods to perform the restrictions. The end-result will be the same.

Create a text file with the addresses you would like to reject. You can choose whatever file name you wish. E.g.: /etc/postfix/smtp_client_access

Its content should be something like: REJECT Stop mailing us192.168.0.2 REJECT Stop mailing us192.168.1 REJECT Stop mailing us

Next, postmap it by running:

postmap /etc/postfix/smtp_client_access

Then add/edit this in your

IP autoconfiguration (also known as APIPA) configures a network interface with an IP address if no fixed IP has been specified, and there's no DHCP server on the network. In this case, an automatic IP will be assigned out of a private range (usually 169.254.x.x). APIPA exists on all Windows version (safe Windows NT).

In case you wish to disable APIPA on a certain interface, you can use the Windows registry to do this. By default, APIPA is enabled on all interfaces, unless it is explicitly disabled.

Fire up regedit. Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\Tcpip\Parameters\Interfaces\adapter clsid, where adapter clsid is the ID of your adapter. If you only h  ...

When running a Synology, take care when you require (or don't want) public (a.k.a. guest) access to shares.

To allow access, first check whether the guest account is not disabled. I found out it was disabled after joining the device in a Windows domain. Disabling the account is a good way to effectively cut off all public access.

If you require guest access on some shares but not on all, be sure to set the ACL for Guest in Privileges Setup to No Access for shares that have to be locked down. Not explicitly setting this will allow public access on that share.

If you're planning on running WordPerfect 9 on a Terminal Server, be sure to provide full access for your users on the registry key HKLM\Software\COREL (64-bit: HKLM\Software\Wow6432Node\COREL).

This fixes the Cannot initialize error when starting WP as a regular user.

Apple has decided that the latest release of their OS, Mac OS X Lion (10.7), is no longer available as an install media. New systems have a recovery partition (called a Recovery HD) with the installation files, and those with earlier versions of the OS (Leopard and Snow Leopard) have to buy it via the App Store as a download.

The last scenario is in fact a hassle if you ever want to reinstall your Mac: prior to installing Lion, you have to install Snow Leopard, then all the updates, before finally downloading Lion. It would be so much easier if one could just install Lion from scratch.

Luckily, there's a way to create an install DVD yourself very easily: the install image is available insi  ...

If you are not able to configure Outlook using the Microsoft Online Sign-in Tool for some reason, there's a way to do it manually.

For this to work, you need the following:

a working internet connection (duh);

your username and password;

your storage location (usually closest to your HQ).

First off, we need the mailbox store server. To find this, you have to log in to Outlook Web Access. Your ICT department should already have given you information on how to do this. If not, use one of the following urls, depending on your location:

Asia Pacific (APAC):

Europe, the Middle East, and Africa (EMEA): https://red002.mail.emea.microsoftonline  ...

If the Show Desktop icon is deleted from Quick Launch, the procedure below will recreate the file.

Open Notepad and enter the following text:


Save the new file as Show Desktop.scf (note the SCF extension) then drag and drop the icon on the Quick Launch bar or whatever location you want the shortcut to appear.

It is possible to enable auto-logon for a computer running Windows, even if the account required is password-protected, or when it's a domain account.

To enable it, you need to set some things right in the registry:

Fire up regedit, and navigate to the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon.

Edit the entry DefaultUserName, and set it to the account you wish to log in with.

Edit the DefaultPassword, and set it to the password required to log in. If the value doesn't exist, create it (its datatype is REG_SZ).

If no DefaultPassword is specified, Windows automatically changes the value of AutoAdminLogon from 1 to 0, effec  ...

A new type of rootkit has recently been seen. While most modern rootkits use the MBR and unused sectors of a harddrive, this one also misuses NTFS metadata to inject malicious code into a running OS.

By default, Thunderbird shows the namespaces of IMAP folders as a seperate folder containing the subfolders belonging to that namespace. An example of this is when you use Google Mail and have IMAP access configured.

An add-on exists for Thunderbird which gets rid of the namespace folder and sorts all subfolders in the root tree:

This is particularly useful for Google Mail where the sent mail, trash and other system folders are stored in a namespace called [GMail]. This way, these folders are stored directly in the root of the tree rather than in a subfolder named after the namespace.

In case of an infection with phony anti-spyware software (such as Anti Spyware 2009), where the EXE file association has been corrupted, use these Registry fixes to reset them to default behaviour.

Be sure to select the right file for your system. XP, Vista and 7 all have different settings.
