IP adress/wireless internet problem, will not renew

Hello experts,

When I try to connect to the wireless internet I get the following message: "Windows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address".

When I enter "ipconfig /all" in the command window, I get the following result:

C:\Documents and Settings\Sander>ipconfig /all

It seems to me (as a noob) that my IP adress is not normal... I already tried activating the dns client, RPC and DHCP in the services.msc, but that didn help.

Can anyone help me out on this one???
