When I was installing a fresh copy of Cygwin, I noticed that some tools didn't work as they normally would. They would bail out with an error.

dig: dst_lib_init: openssl failure

A quick search on Google shows that there's a dependency error. While the openssl libraries are installed, the openssl package is also required. After installing that package too, it worked again.

Since Windows 2000, you can use the convert tool to convert FAT32 partitions to NTFS, provided that enough free space is available to perform the conversion. Any drive can be converted "live" (although the system partition requires a reboot).

To run a conversion, you'll need the drive letter and the volume label. Fetch it using Explorer or by running a command on the command line:

vol C: Volume in drive C has no label. Volume Serial Number is A83C-E4E8

Next, run the conversion command. If you're converting the system partition, you will have to reboot to complete the conversion.

convert C: /FS:NTFS

This will perform the conversion. Note that it will probably take s  ...

Every two years, the self-signed SSL certificate expires, and has to be renewed in order to ensure your users can continue to connect to the server. This renewal is not difficult, and can be done in a few steps.

Go to the Windows SBS console, navigate to Network, then Connectivity

Click on the certificate icon, and choose view certificate properties to check the expiration dates. If it is expired, continue with the next step.

In Connectivity Tasks, choose to Set up your internet address, and follow the steps. At some point you'll need to enter your domain name (which should be set to the current). If required, adjust your prefix (by default: remote) Upon finishing the wizard, a new self-s  ...

By default, Lion's new Launchpad application is what it is: it contains all the applications installed on your Mac. With Launchpad-Control you can configure which applications are shown and in which order. It's a very neat and handy tool to configure Launchpad just the way you want it.

Create a folder with the contents you want on your ISO.

Open Disk Utility and use the New Image from Folder menu item to create an image. Ensure it is uncompressed and use the CD/DVD master option.

In my experience this creates HFS+ masters which are no good in Windows.

Open the Terminal

Assuming your new image is called ~/Desktop/Master.cdr (the file is on your desktop and called Master.cdr) type:

cd ~/Desktophdiutil makehybrid -iso -joliet -o Master.iso Master.cdr

This will create an ISO/Joliet .iso file.

When converting a DVD, be sure to use the option -udf instead of "joliet" to generate an UDF filesystem. This is particularly important with DVD video master  ...

You can clear the DNS cache on a Mac by using these commands (depending on the version of OSX you're running):

  • Tiger (10.4): lookupd -flushcache
  • Leopard and later (10.5+): dscacheutil -flushcache

Had some trouble on a Sony VAIO VGN-Z41WD which has been upgraded to Windows 7 by performing a complete installation. After installing just about every driver and after installing the necessary components for WWAN for 3G access to the internet, the software just bails out with an error stating it can't find the device.

A closer look in device manager reveals no sighting of said adapter. At first, I thought the device to be broken until I started thinking a little further. The manual states that devices can be turned on and off via the VAIO Control Center, meaning that the device could be presented but not powered on (thus, not appearing in device manager).

Only after installing the   ...

If you're running RDS on a vSphere server with VMware Tools installed, you may have noticed the evergrowing presence of vmwaretray DMP files in the user profiles. These are crash dumps from the VMware Tray icon, which is ran during every session.

The reason for this crash dump is an error which is caused by lack of read access to a certain key in the Windows registry by your regular (domain) users.

This key is called HKEY_LOCAL_MACHINE\Software\VMWare. Inc.\VMWare Tools.

Set the permissions on that key to read access for the users logging on to the server, and your problem should go away.

Hint: you may also wish to remove the icon altogether. This is done by setting a certain registry va  ...

If you're running RDS on a vSphere server with VMware Tools installed, you may wish to remove/hide the system tray icon. This can be done by setting a certain registry value.

The registry value is:

  • Key: HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware Tools
  • Value: ShowTray

Change the value to 0 will effectively disable the icon the next time a user logs on.

Never unsecurely transmit passwords and other sensitive info via e-mail again. Just use One Time Secret will ensure that the sensitive information can be viewed only once. This allows for easy and secure transmission of passwords, VPN keys and the likes.

You can remote-reboot your Polycom phones from the Asterisk CLI by sending a SIP NOTIFY command. This command instructs the phone to recheck its configuration, and therefore, will reboot when certain parameters have been set in your phone configuration provisioning.

Make sure the following directive is set in your provisioning config:

<specialEvent voIpProt.SIP.specialEvent.checkSync.alwaysReboot="1" />

You find this in sip.cfg, or you can set it in your own configuration (mine's called aaps-settings.cfg, but that's just an arbitrary name).

When setting this variable in your own configuration, be sure that it's set in the right context, like so:<localcfg> &l  ...

In SBS2008 and 2011, there's a wizard allowing you to move the WSUS repository to another partition/disk. However, it does not move the state database, which, over time, can grow a bit large. Luckily, one could manually move the database by stopping WSUS, detaching the database, move the files, reattaching it, and finally, starting WSUS again.

First of, stop the required services (WSUS and IIS Admin Service)

net stop "update services"net stop w3svc

Next, detach the database:

sqlcmd -E -S np:\\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query -Q "sp_detach_db 'SUSDB'"

Move the SUSDB.mdf and SUSDB_log.ldf to their new location. Then, reattach the database:

sqlcmd -E -S np:\\.\pi  ...

Each time Google Chrome gets updated, it leaves behind the old version of Chrome. While this comes in handy when you have to downgrade, it also builds up (precious) hard disk space. You can, however, manually remove the old installation files.

Google Chrome is installed by default in your local profile folder, at:

%USERPROFILE%\Local Settings\Application Data\Google\Chrome\Application

In that folder you will find the main executable (don't remove that) and the different versions of Chrome.

You can simply delete the lower version numbers so that only the highest version remains. This clears out on average 80-100 MB per folder (although it could very well be much more).

A neat plugin for Pidgin is Lock-n-Roll.

Download here:

It automatically sets your status to Away, and sets a predefined status message, upon locking your computer (or when it gets locked via screensaver).

The problem is related to incorrect hinting of the webserver, tricking IE7/8 into believing you are in fact downloading a ZIP-file, rather than an Office 2007/2010 file. The reason for this is because these files are in fact XML-files, compressed to a ZIP, but have a different extension, indicating it's not a regular ZIP-file.

There are two ways to fix this. The best way would be to change the webserver (if possible, ask the administrator of the webserver you are downloading from) to add the correct MIME-types, so the webserver provides correct hinting. How this is done, depends largely on which webserver is being used.

When using Apache2, there are two ways to resolve the issue. Either ad  ...

There's an obscure issue with Access 2003, not being able to open an MDB from a network location via Explorer. It outright refuses to open the file, so when attempting, nothing seems to happen.

This is caused by security measures in Access 2003, where you normally have to confirm to open the file, which fails. However, I'm guessing this is not by design that it does not open at all.

A workaround is to create a shortcut to said file, then edit the shortcut so it reads:

"C:\Program Files\Microsoft Office\OFFICE11\MSACCESS.EXE" /NOSTARTUP "MyFile.MDB"

Adjust the installation path and file location to your needs.

This way, Access gets started first, with the file as parameter, so it gets op  ...
