I am trying to get a fresh installation of Win2000 Pro (retired company computer, Dell Optiflex GX240) to 1)  connect to the internet via DSL and 2) connect to a home network.  This is with a fresh INSTALL of the OEM-supplied OS disks.  The computer can connect to my home network with static addressing (IP and Subnet made to match the IP ADDR of the other machines on the network changing the last number) but not with dynamic addressing.  But internet is not found via Internet Explorer with dynamic or static addressing.  I also tried connecting the ISP-supplied DSL modem directly to the computer and that also does not work. 

I am doing this for free for a fellow employee, so cannot take it to a SHOP (which is what my ISP help line suggested this weekend).

There might be a clue in the behavior of ANOTHER machine on the network.  Less pressing is my own problem getting an eMachine running Windows XP to connect to my network using dynamic addressing.   I can get on with static addressing made to match the other IP addresses and Subnet Mask on the network, but then, I cannot get internet on that machine.  The problem is similar to the Win2000 problem described above, so I though I would mention it.  But I am sure it is not a problem with the router, as I have tried different ports, different cables and the problem stays with the one XP machine (and the Win2000 belonging to my co-worker).  The other machines on the network are 1 running Win98 and 3 running XP.  Win 95C also works.

Thanks for reading. Thanks for being here.
Larry Try a new Network Card.Make sure you have not configured these computers to logon through a domain name (as they would in the corporate network).  Right-click My Computer, select Properties, select Computer Name.  Under Workgroup, they should all have the same name:  calling them all "Workgroup" is handy.

Since you have:  1 running Win98 and 3 running XP.  Win 95C also works", it's not the router.  You didn't say if these 5 are DHCP.
