Your global TCP/IP settings may conflict with the TCP/IP settings for your connection to Safe-t.net.

Note:
Be sure to write down any settings that you change while performing the following steps. If your computer is connected to a network and you are using the TCP/IP protocol to access the network (in addition to the Internet), you may need to change the settings back after the problem has been resolved.

To edit global TCP/IP settings

1. Click Start, point to Settings, click Control Panel, and then double-click Network.

2. On the Configuration tab, click the TCP/IP protocol, and then click Properties.

3. On the IP Address tab, make certain Obtain an IP address automatically is selected.

4. On the Gateway tab, make sure no gateway address is installed.

5. On the DNS Configuration tab, verify that Disable DNS is selected.

6. Finally, press the OK button. This takes you back to the original Network dialog box. Press OK once more. At this point the system will prompt you to restart your computer.
If these steps solved the problem then there was a conflict between the global TCP/IP settings and the settings for Safe-t.net.
