internet connection sharing question

i'm running win2k pro on both pcs, one of them has two lans with ICS enabled...

the problem is that the client cannot access the net - file sharing works and both pcs see each other in network neighbourhood, but if i ping the client from the host and vice versa i get a timeout error on all 4 pings. the router pc can access the net fine, it's the client that doesn't see the internet.

i'm using a crossover cable to connect the client to the host and i think that might be my problem - any help?

Use Winroute (4.2) and all your troubles are over!

maybe they are not in the same ip subnet? ex, the ICS computer has 192.168.0.1 and the other one has 192.168.1.12, change the other one to 192.168.0.12 and maybe that will work...

thanks for the replies!

the ICS ip is 192.168.0.1

the client ip is 192.168.0.108

both run zonealarm pro, but even if i turn it off on both, nothing works. i'd be glad to use winroute, but is the built-in firewall as good as zonealarm? plus it's really expensive and i don't feel like searching for a crack ... i read on the newsgroups that many people with win2k pro have this problem... not in 98... yet another way microshit screws us?

how does the internet go into the host computer?

is it ASDL/cable modem -> ethernet1 on host, then on ethernet2 on host to (via crossover)ethernet 1 on client?

everything is exactly like you said, only instead of an ASDL/Cable modem i'm plugged into a wall jack at uni - could that be a problem?

i thought that when you use a box as a router, the clients send requests to the router, which in turn sends requests to the site, gets the stuff and routs it back to the client. is that so?

The Microsoft's ICS is a nice idea, but it simply didn't work for me even though I did everything by book, so I had to install WinGate back then. Now I'm just using hardware router.

Well, maybe some guides would help you.

double check ethernet 1 and ethernet 2 on the host pc are NOT defined as a network bridge (doubt that will be the case though)

otherwise contact the uni tech support and ask them, if they go on about havin 2 pc's just say ones a mates laptop and you want to back up files on the main pc!

double check both etherner cards on the host pc have the right drivers etc as well

Do you have the same subnet mask? 255.255.255.0 on both?

Posted by whiskers on Sep-01-2003 19:14:

all right, i installed wingate but it doesn't work

the problem is that both pcs see each other on the LAN and i can access files, BUT they don't reply to pings... and what's even more baffling, is that the server accesses the internet absolutely fine, YET pinging websites gives me a timeout request... ARGH, why can't the pcs reply to tcp/ip pings????

When I was in college they gave us a 4 port hub for the room if we had more than one computer hooked up (each roomate having one). There were several guys who had more than one computer each. One guy even got an 8 port hub from the res hall cause he and his roomate each had 3 PCs.

I don't know what their policy is where you are about number of computers but I would guess the net support guy there is probably the easiest way to go since he/she/it can troubleshoot from both ends.

all right, thanks guys, i think i'm gonna get a hub, it'll save me lots of pain. hope it works though, because the main router or whatever they have here assigns my computer name to my account name, so if i wanna connect another computer to the net, i'd have to restart it... but whatever, we'll see what happens. thanks for your help.

If it assigns a single computer with an IP address, get a Cable/DSL router and after you have set one of te computers up with their funkiness have the router clone that PCs MAC address. It should work like a charm then. I got a DLink router for my mom for 20 bucks at best buy.

I am sure the net guys would be able to get you set up without being overly sneaky though. I would guess that a lot of college students these days have more than one computer.

FUCK, this is bizarre!!! just got a hub, set it up in minutes. everything's working fine... then on that same pc that couldn't access the net earlier all connections stop working EXCEPT for aim and ONE IE window, all other windows would give me a "server cannot be found" error...

restart - nothing works at all. i can see my lan, can access and ping the other machine, but I CANNOT SEE the internet and i cannot access my hub from this machine (although it DOES reply to pings)!!! (i have to log in @ 192.168.0.1). all the correct hub lights are on and blinking... i rechecked all settings, uninstalled and reinstalled the card (including switching pci ports)... i'm practically tearing my hair out here...

wtf is wrong? all settings are correct, it was working, and i didn't touch anything! what is it? faulty cable? faulty card? then how come LAN filesharing works??? plus i swapped the cables between the working pc and the non-working one and nothing changes... what is wrong???/ ARGGGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!

Find out what the DNS server address is on campus from a net tech.

Then manually enter that into the DNS tab in your net prefs (dunno where it is in windows off hand).

Your symptoms look to me to be a clear indication of no DNS lookup. If you can access things like AIM it is not an issue of being able to connect, it is an issue of resoving the domain names into IP addreses. AIM and MSN use a nmber of static IPs to connect to their services.

MrS

the problem is that i can't connect to anything anymore. aim just sits there saying "connecting to server" and never gives me a "cannot connect" error. i found some message on google groups of a guy having the same problem on a 10-pc network, but the thread doesn't have a solution. and both pcs have identical settings for masks/dns/ip obtaining etc.

hehe, the ironic part is that in my week of being at uni i

a. spent more time troubleshooting my network than doing homework
b. learned more about computers on my own rather than in classes (i'm a compsci major)

but fortunately, i was able to realize that since reinstalling tcp/ip didn't help, there must've been a deeper problem...

so in case some of you encounter this same idiotic trouble, here's what you should do:
