To work around this problem, obtain an IP address from the DHCP server before you open the PPP connection. If this problem has already occurred, disconnect the PPP connection, and then renew the IP address from the DHCP server before you open the PPP connection. Sometimes, you may have to restart the computer before you can renew the IP address.

To renew the IP address, follow these steps:

1. Click Start, click Run, type CMD in the Open box, and then click OK.
2. At the command prompt, type ipconfig /release, and then press ENTER. The IP addresses will typically both be 0.0.0.0.
3. Type ipconfig /renew, and then press ENTER. The DHCP server will now provide the correct IP address.
