Group,

I spent a considerable abount trying to figure out what is going
on with my network partially working and partially not.

I setup a Win2k3 server, DNS, and DHCP. The server is allocating
IP's to the clients however not routing them to the Net. I have all
clients set to the default gateway and have the appropriate forwarders
set for the server. For one brief moment yesterday it worked.

Now the only client in the group ( a laptop running XP Home ed. ) gets
through to the net. My Win2k and XP Pro clients don't get through. They
do get an IP and register in AD. However I did notice that the XP Home
machine isn't registering it's full name (cpu.compxyz.loc). It's just
registering
(cpu.) and it gets Net? The other machines running 2K and Pro register they're
full name (cpu.compxyz.loc). They don't get net.

I suspect the server thinks it's a pre 2K machine and uses NetBIOS to let it
through? When the XP Home is connected I can run a "show NAT translation"
on the router and see that no machine is getting a global outside IP..

Any ideas or suggestions would be a big help. Thanks in advanced.

Try:

1. On a Win2k or XP Pro machine, ping 4.2.2.1. If you get a time out, you
have a routing issue.

2. If you get an echo response in #1, ping google.com. If you get a host
not found error or timeout, you have a DNS issue.

3. If both #1 and 2 are successful, open Internet Explorer. Click
Tools/Internet Options - Connections tab. Select Never dial a connection
and click LAN Settings. Clear all check boxes - OK. Click Apply and close
IE. Open a command prompt and run ipconfig /flushdns. Open IE.
