Getting WWAN to work on a VAIO after upgrading to Windows 7
by lunarg on November 15th 2011, at 16:38
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 b  ...
 
vmwaretray DMP files in user profiles
by lunarg on November 14th 2011, at 15:29
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.

Remove VMware Tools icon from system tray

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.

Remote-reboot Polycom phones using SIP NOTIFY
by lunarg on November 4th 2011, at 14:51
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).

Notice
