Internet Connection

I am replacing an older Dell Dimension XPS with a 2 year old Dell Dimension 4600. The newer unit was a relative's and they've gotten a newer computer. They connected to the net with a dial-up modem.  I connect to the internet via a cable modem to Comcast.  I have not had any trouble with the " old " unit and connectivity.  It took me some days but I was finally able to connect the two units and succesfully transfered all of my files and settings. I followed the instructions on Microsoft's pages to no avail.  And I was not able to transfer files by using the XP cd's.  Finally I used the tranfer file link in the accessories part of the start up menu and it worked fine.  My problem now is that even after transfering files I am not able to to connect the " new " computer to the net via the cable modem.  I have been around the world on ever Dell chat line availible only to be sent to links and then suggested that I call the $90/hr support desk.  Happily I have a warranty, but alas, they are closed on the weekends. When else do I have the time to call?  I have at the direction of the support link, reset the ipconfig and so forth.  I tried using the winsockfix mentioned in this forum.

 

I can switch between the "old" unit; still works great; to the new unit; no connection; and back to the "old" unit; continues to work great.  I was able to tranfer files from the "old" to the "new" with no problem.

 

Aside from the " page not found" message, the connectivity icon tells me that " unable to contact DHCP server."  I am about to find a bridge to throw the new 'puter from if I can't figure it out soon.  I'm considering wiping the whole hard drive and starting over.

Thanks
