check your network connection. do you have a link light? can you ping the domain controller? did this ever work? what may have changed? if link light but no ping, check for valid ip address...(from command prompt, ipconfig <enter&gt try ipconfig /release ipconfig /renew if no ip address comes up...try setting static ip address to help troubleshoot...if linklight and ping both work, check gateway settings. try swapping network jacks and try changing media type settings on the network card. maybe lock it down to 10MB half duplex or up to 100MB full duplex...
