Ok, this morning, Comcast did their switch for the internet service in my area.

when I turned on the comps. I could connect to the internet fine, but now my home network is hosed??? If I shutdown both computers,

turn off the cable modem, and boot up, then I am fine on the home network again ????

Setup:

Two computers (windows XP pro)

NIC from each computer goes to the hub and upload port of the hub is the cable modem input.

TCP/IP set for automatic detection of IP address and DNS server (same as always before)

NIC configured for: Client for Microsoft networks, File and Printer sharing, and TCP/IP

Any ideas what I should try to get both my home network and the internet working again?

(I have run this setup for nearly a year and a half with no probs... only change is the Comcast service switch)

Thanks in advance!
 
So you don't have a NAT router in this setup?
Were you paying for multiple IP addresses?

Maybe they farked the setup and you aren't getting two addresses any more.
Which would mean your machines wouldn't have IP adds on the same net any longer.
 
Check the IP addresses your machines are receiving.
I'm betting they aren't on the same network anymore, or that you are only receiving one now.
 
w00t!

this from Woodie in the OS forum:



<< I'm suspicious of DNS settings...it sounds like:

When Cable is down:
machine1 tries to find machine2, DNS fails rapidly, so switches over to broadcast, and immediately finds machine2.

When Cable is up:
Machine1 tries to find machine2, DNS succeeds or takes a long time to time-out, so machine1 never switches to broadcast to find machine2.

Can you ping the other machine by name? w/ and w/o the Cable being up? Are you using the FQDN for the other machine? Does that make a difference?

You could install NetBIOS (protocol) on both machines, and make it the default protocol. Then disable NetBIOS over TCP/IP. More secure, and would take the cable service out of the loop for LAN connectivity.'

That solved it.... thanks to all of you for the help...
 
under protocols, it was called "NWLink IPX/SPX/NetBIOS Compatible Protocol

PS: Chalk another one up for Comcast "Support"... They had no clue how to get me goin'
 
I see. You installed IPX. Or NWLink, MS's version of IPX/SPX. Thats fine too. NetBEUI is not an installable option in XP. Can still be installed but you have to jump through some hoops and get it off the CD. IPX/SPX serves the same purpose if you leave NetBIOS enabled and disable it for TCP/IP. Takes care of your local file sharing. Not quite as secure as NetBEUI since it is a routable protocol but I wouldnt worry about it. NetBIOS is more of a service than a protocol. Thats my opinion anyway. You'll find different definitions if you look it up. It's installed by default however and is not, by itself, a network transmission protocol. NetBIOS hops on the back of a protocol. In your case IPX/SPX. That is the default netware (Novell) protocol, or used to be before Netware 5, just as an FYI.
 
thx ktwebb!

I haven't ever had to deal with any of the networking "innerds" before, so this has been a bit overwhelming.

However, I do like learning about it and your insight is welcome.
