Windows Vista cannot obtain IP-address from my Internet Service Provider

/0 Comments/in /by

Under certain conditions a PC running Windows Vista is unable to obtain an IP-address via DHCP from the Internet Service Provider (ISP). The problem occurs if the ISP is running a non-Microsoft DHCP server. Among ISPs it is common to work with, for example, ISC DHCP-server which is the most common DHCP-server in the world.

The problem and a possible solution is described in the following Microsoft article:

http://support.microsoft.com/?scid=kb%3Ben-us%3B928233&x=13&y=10

If you don’t want to edit your registry another simple solution is to buy a simple broadband router (internet sharing device) that does Network Address Translation (NAT). By doing this, the broadband router is obtaining the IP-address from the ISP, not the Windows Vista PC. In addition, you will be able to connect more than one PC to your Internet connection and those PCs will be protected by the firewall that most broadband routers have builtin.

A new mail notification that occurs on the system tray looking like this:

Mysterious new mail icon in system tray

Nothing will happen when you hover the mouse over it or clicking on it. It is hard to understand which software this icon belongs to.

The answer is Vodafone Mobile Connect which is a software used to connect with 3G mobile networks as well as WLAN/Wifi networks using built in devices in your computer. It is being shipped with HP Compaq laptop computers for example.

The icon indicates that you have new unread SMS messages in your mobile device. To read the SMS click on the red Vodafone Mobile Connect icon in the system tray. You can see a bit of the red icon in the right edge of the picture above. Then choose “Show” and then “SMS” in the Vodafone Mobile Connect software.
