Can not go to internet after doing online update with YOU

Dear my friends... I use SuSE 9.2. My internet connection is through the LAN of the company where I work. Before doing update with YOU (YaST2) I could go to internet. I downloaded and installed all patches at the moment. Once, I restarted me computer then I can not go to internet anymore. I use DHCP and automatic DNS for my NIC. I can only do ping to it self this way: " ping 127.0.0.1 ". Please tell me what happened and what is the solution of my problem. Thanks in advance. __________________________________ Do you Yahoo!?
