Ok i have a windows 2k machine on a network without a domain.  I have tried different NIC cards and cables and every possible thing but software.  I can run a ping and ping our routers and even open other computers on the network.  BUt I cannot get to the outside world ( msn.com or whatever).  I have already repaired internet explorer 6 and are currently trying to repair any files useing the sfc/scannnow or whatever that command is.   ANy ideas?  Thanks in advance

Hi kleigh,

Reset your winsock and tcp/ip stack:

Greetings,

ipconfig =
ip = 206.95.46.28
net = 255.255.255.128
gate = 206.95.46.126
dns = 206.131.229.9
     = 4.2.2.1
if I ping those addresses they show no host
no dhcp
no route
no wins
broadcast

that IP address is www.experts-exchange.com
If you can ping by IP and not name... more than likely a DNS problem.
check your dns settings and servers... can you ping them?
Are they local or ISP servers?

Insert the IP address I gave earlier and press enter.

Have you checked to make sure your DNS settings are correct in your Network Configuration? No typos, primary and secondary running correctly, etc...
Also check the Advanced DNS settings (by clicking advanced on the network properties where your IP and DNS are setup)
Are you running DHCP or Static settings?
Have you been attempting to ping the DNS by IP or computer name?
Netbios may work, without your DNS being correct.
